Positioning Equipment

The OPTITEST line offers a wide range of accessories to solve positioning and alignment problems. In addition to the standard positioning equipment presented below, TRIOPTICS is supplying special holders and stands made according to specific customers requirements.

Clamp Fixtures

The clamp fixtures are mounted on a base plate with 4 fixing screws and 4 pressure screws. The pressure screws prevent a loosening of the fixing screws and allow a certain levelling within a small range.

Two Axis Adjustable Holder

This unit provide two axis fine adjustments for azimuth and elevation. It also incorporates clamping screws to securely hold the autocollimator.

Autocollimator Stand

Coarse Travel Stand (Type A)

Features

The Autocollimator Stand A is a simple stand featuring a precision rack and pinion slide mechanism for height adjustment of the autocollimator. The Stand A is equiped with a clamp fixture D 38 mm.

Further provisions are made for mounting of a tilt table D 100 mm. Alternatively a rotary table D 100 mm or a combination of tilt and rotary table can be mounted on the Stand A.

Applications

The Stand A is designated for angle measurements of plano optics as wedges, windows, prisms, etc.

Fine Travel Stand (Type B)

Features

The Stand B has two travel mechanisms: a coarse travel and a coaxial ultra-fine focusing mechanism. The ultra-fine mechanism is especially useful in applications where a smooth, precise motion of optical instruments or subsystems are required. The bottom body of the stand contains a clamp fixture for a collimator D 38 mm and an adjustable mirror for beam deviation. A second clamp fixture D 38 mm attached to the travel mechanisms is used to hold autocollimators and telescopes.

Further accessories can be attached to the Stand B:

• tilt table
• rotary table
• precision self-centering rotary holder for centration measurements

Applications

The Stand B is ideal for measurements in transmission (centration errors) or reflection (radius, centration, etc) of spherical optics. Angle measurements of plano optics are also possible of course.

Fine Travel Stand (Type C)

Features

The Stand C is similar with Stand B, however, two transversal translation stages with micrometer are supplimentary provided. One of this stage allows to transversally move the clamp fixture with the optical instruments (mostly autocollimators or telescopes). The second stage is used to translate a reticle (mm scale) mount for measurement purposes.

Applications

The Stand C is ideal for measurements in transmission (centration errors) or reflection (radius, centration, etc) of spherical optics. The two additional micrometer stages are used for focal length measurements.

Tilt and Rotation Tables

Tilt Table D=100 mm

Three fine adjustments screws allow the tilt along two axes. Two threaded holes M4 are provided for attaching further accessories. The tilt table designed for measurements in transmission have a central hole D=15mm.

Rotation Table D=100 mm

The rotation table features complete 360° rotation. After clamping the table in the selected position, a tangential micrometer enables a fine rotation adjustment.

Tilt and Rotation Table D=100 mm

The tilt and rotation tables are modular and can be mounted together with the tilt table either on top or at bottom.

Self-Centering Holders

Trioptics Self-Centering Lens Mounts reliably center and hold optics and cylindrical objects. The centering accuracy is far above the commercially available self-centering mounts. To ensure the precise axial position of lens cells and mounts, the three support rods have an accurately ground step. This secure not only a repeatable radial centration but an exact axial positioning as well.

Ultra-Precision Rotary Holders

The Self-Centering Rotary Holders are designed for best possible centration and rotation accuracy required in measurement of centration errors of optical components and systems. The Self-Centering Rotary Holders incorporates an indexing mechanism at 90° for centration measurement with Trioptics automatic optical stations OPTOMATIC and OptiAngle. This indexing mechanism can be simply switched off when used in other applications.
