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.

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 equipped 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 A)
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=100mm
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=100mm
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=100mm
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.

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.
