Design Philosophy

Our equipment is designed with a modular framework. This permits the user to select the needed functional devices and have them work well together. This way, custom equipment, matching the requirements of the application, can be assembled efficiently. Changes in capability can also be made during the functional fife of the equipment.

Equipment Selection

We routinely manufacture several series of equipment that perform the same basic task. Each series has its own characteristics with different performance levels. This is true for XYZ manipulators, translators, linear-rotary feedthroughs. etc. If in doubt. please contact us to discuss your particular application. Perhaps we can suggest a successful and more cost-effective way to obtain the desired result. In most manipulator applications, the sample size, degrees, and range of freedom, and need of accuracy and rigidity determine the exact specifications of the equipment required. Increasing levels of versatility tend to increase the needed bellows size and thus the required superstructure. This can escalate into larger equipment and greater cost. Careful establishment of the needed requirements will minimize the cost of the equipment and assure performance consistent with your expectations.

Layout Drawings

Layout drawings are available for all our standard products. These provide the dimensions required to ensure the equipment will fit in or on your system. Many of these drawings are shown in this catalog. All our media (models, .STEP files, pictures, manuals and more) can be found here: PRODUCT MEDIA

Manipulator Terminology (FB Manipulator shown)
Terminology

We have adopted the following functional definitions when used in reference to our equipment.

Manipulator (X, Y, Z)

A manipulator is a 3- axis (X. Y, Z) positioning device. For most applications, the instrument hardware is mounted outside the vacuum chamber. with a welded bellows providing a flexible vacuum curtain. The X axis passes in front of the vertical, mechanical structure, or “backframe,” with the Y axis moving to and away from the backframe. The Z axis is perpendicular to the X and Y axes and moves up and down directly against the vacuum pressure differential. The polar axis is the same as the Z axis. The polar axis is also referred to as theta (θ).

The limit of X and Y travel is normally a circular pattern. The range is indicated as a vector sum. This means a± 1/2″ range of X and Y allows the polar axis to be moved anywhere inside a 1″ diameter circle. The sum of the X and Y vectors is limited to .5″. Square pattern XY stages are available as options on some models.

Translator (Z)

A translator is a single axis positioning device, utilizing a bellows as a vacuum seal. They are also referred to as a “Z only” stage. This axis is normally perpendicular to the chamber. This causes the Z axis to work directly against the force from the pressure differential.

XY Stage

The XY stage provides the X and Y axes only. No Z motion is available.

Polar Rotation (θ)

The polar axis is the same as the Z axis, above. Rotation about the polar axis is commonly achieved by mounting rotary feedthrough at the center of the traveling flange of a manipulator or translator. This degree of freedom can also be achieved with a differentially pumped rotary seal.

Azimuthal Axis (α)

The azimuthal axis (α) is perpendicular to the polar axis (θ). Sample azimuthal rotation refers to rotation of the sample about an axis normal to the sample face and perpendicular to the polar axis.

Flip (β)

Flip motion is the changing of an axis normal to the sample face from parallel (or coaxial) to the polar axis to coaxial with the azimuthal axis. The range of this change of axis may be 90°, 180° or full 360°.

Tilt (γ)

Tilt refers to changing the polar axis with respect to the X, Y and Z axes. This is usually done at the traveling flange of a 3-axis manipulator (or other exterior mounting stages). Tilt range is often limited by the bellows I. D. and the O.D. of the probe passing through the bellows. The maximum angle practical is about ± 7°. When used in this manner, translation in X, Y and (slightly) Z will occur with adjustment of the tilt angle. Tilt stages are available in single or dual-axis units.

Bolt Pattern Orientation

Our equipment is manufactured with the primary axis straddling adjacent bolt holes on the mounting flange (American Standard). Most equipment can be supplied with the axis passing through a bolt hole axis (European Standard) on request. Some equipment is field adjustable.

 

Custom or Modified Equipment

Our goal is to provide researchers with the high-quality equipment needed in their endeavor. Our modular design philosophy allows us to tailor standard instruments to a particular application at a minimum cost. Often, fully meeting a customer’s equipment requirements means making a modification to existing instrument design. It may mean designing a new unit to the customer specifications. We accept this challenge as being part and parcel of our commitment to assist the researcher. Indeed, many of our new equipment designs are outgrowths of responding to specific customer needs. We have even interfaced with our equipment and sample handling with that of many other manufacturers.

We strive to supply this design and manufacturing service as efficiently as possible, both in terms of price and delivery. We encourage you to contact us so we can communicate your equipment needs. We are comfortable bidding to your specifications. Our standard policy is the customer reviews and approves the design drawings before custom equipment is manufactured.

FM Series Compound Precision Manipulators

The FM series compound precision manipulator combines the XY stage from the FB manipulator series with the Z stage from the EMT precision translators. This combination works well vertically or horizontally. The FM series is available with horizontal mounting packages with custom-rated counterbalance springs to maintain “instrument”‘ positioning. The Z stage can be separated from the XY stage.

The FM series compound precision manipulators are XYZ units utilizing two bellows. A large I.D. short bellows located at the base of the unit is used to provide the XY operating range. A smaller I.D. bellows supplies the Z axis travel. XY bellows I.D.’s of 2″, 2.5″, 3″ and 4″ are standard, with inside diameters to 6.3″ I.D. possible. These units are available with ±0.5″ or± 1″ of X and Y travel. They can be supplied with Z travel of up to 36″ or more, with Z bellows I.D.’s of 1.04 “, 1.39″ and 1.87″ standard. This approach provides considerable savings over the single large I.D. bellows systems, where a clear bore is not required, and significant Z travel is needed.

A non-rotating tubular probe can also be provided with a stabilizing linear bearing at the base of the Z stage. This results in a more stable probe assembly, with a shorter effective “lever arm.”

This probe option provides a centerless, ground, hollow. stainless steel tube extending through the center of the manipulator bellows. This probe is mounted to the traveling flange with a double-sided flange and can be easily removed for equipment installation. This tube is stabilized by a stainless-steel linear bearing mounted at the base of the Z travel system. This bearing dramatically improves the stability of the probe.

In addition, differentially pumped rotary seals can be fitted to these manipulators. They provide an additional degree of rotary freedom for the customers’ equipment. The probe bearing can be modified to allow probe polar rotation as well as polar axis linear travel. This system provides an –excellent method of utility delivery without utility line motion in a vacuum.

EMT Series Precision Translators

EMT series translators provide a single axis (Z only) motion. These translators are based on the EM-200 series manipulator Z drive. They are calibrated in 0.001″ increments with 0.100″ travel per turn with a coarse side scale. They are available with four different bellows I.D.s. The standard base (stationary) flange is 2.75″ 0 .0., with larger O.0.s optional (required on longer travel units). The traveling flange is 2.75″ 0 .0. Both flanges are supplied tapped as standard, but we can supply clearance holes with appropriate neck assemblies to accommodate those applications which require it.

Assemblies are available with or without axis tube probe/bearing assembly.

The 2.75″ and 4.5″ 0 .0. flanges are rigidly attached to the traveling and base structure in a special way. The “Super Grip System” holds the flange about its perimeter by means of a tongue and groove, providing positive, rigid attachment with the greatest lever arm possible. The flange (and thus the bolt pattern) is adjustable to any orientation.

The EMTX Series translator is available for applications where longer strokes and/or larger payloads are required.

Tilt Systems

Tilt stages allow a precise angle alignment to be established (and repeated) between two flanges. When the base flange of a tilt stage is attached to the chamber flange (or traveling stage of a positioning device) and a probe is attached to the tilting flange, probe angle and tip position can be changed.

Tilts can also be used as an inexpensive method to align docking systems and actuate sample transfers. The TLT series was designed for that purpose and is constructed for cantilever (horizontal) loads. TLT tilt stages are available in single and dual-axis units.

VXT Series Virtual Axis Tilting/Positioning Assembly

The VXT series precision tilt was developed to hold and position larger excitation sources or special detector systems.

Typical applications include positioning of larger electron guns, UV or X-ray sources, as in ESCA-XPS applications or RHEED studies. The extreme flexibility of positioning allows for concise targeting.

This device provides five independent degrees of freedom. The critical freedom is the ability to “pivot” the source/detector about the target. with a point on the target surface becoming a focal point or “virtual axis” point of the motion of the VXT.

The arc radius guides are custom-made to suit specific target-to-flange distance requirements.

The stepping motor option can provide automated arc-scan motion.

The VXT is particularly suitable for payloads up to 35 lbs in vertical operation.

When using an X-ray slit source or a polarized excitation source. a differentially pumped rotary seal can be mounted to the VXT and the source on top. This configuration allows the source to be rotated about the polar axis and then scanned about the virtual axis focus point.

RNN Series Differentially Pumped Rotary Seals

Differentially pumped rotary seals (RNNs) provide 360° of continuous rotary freedom through the vacuum wall of a UHV system. The RNN has two stages of differential pumping isolated by graphite-impregnated, expanded, Teflon seals on special sealing surfaces. A pre-loaded ball bearing set accurately controls the rotating stage position. This allows the unit to be successfully used with manipulators and other precision positioning devices.

RNNs are available with worm drive fine adjust option. This allows for easier and more accurate angle adjustment. RNNs are also available with anti-backlash stepping or synchronous motor drive.

RNNs with up to 12″ I.D. are listed. Larger I.D.s have been built with excellent performance. Please consult factory for special applications.

RNN Series Specifications

■ Models with clear inside diameters of 1.53″ to 10″ standard (see table). Larger sizes on request. All units are bakeable to 150°C

■ Stationery and rotation flanges, tapped

■ Flange face-to-flange face distance approximately that of two Con Flat-type flanges of the corresponding size

■ 2 stage differentially pumped
