OptiAngle® is a PC-based Optical Test Station that can accurately measure angular displacements, centration errors and other parameters of optical components and systems. To achieve this, the system incorporates visual autocollimators and CCD-Cameras connected to PC-frame grabbers.
 
User-friendly Windows-based software guides the user, improves dramatically the measurement accuracy and provides advanced data management. A large variety of modular optical and mechanical accessories extends the range of applications. This modular approach enables OptiAngle® to be configurated or upgraded according to the operator’s requirements.
 
Since the basic principle of OptiAngle® is to detect and measure displacement or distance between two crosslines viewed through eyepiece and CCD-camera, the applications are derived from the optical set up of the instrument.
 
Measuring capabilities include:
 
PLANO OPTICS
 

wedge angle;

90°-angle of prisms;

parallelism of plane plates;

mirror tilt;

deflection angle through and prisms, etc;

pentaprisms;

prisms angles in connection with a swiveling autocollimator holder;
 
SPHERICAL OPTICS
 

centration errors measured in transmission and reflection while the sample is freely rotated
 
CD-DISC AND CD-ROM OPTICS
 

alignment of CD-optical heads;

wobble of rotating glass discs; Compared to the visual optical testing, the image processing software provided with OptiAngle® offers a lot of advantages:
 

increased accuracy by approx. factor 10;

measurement of rotating samples;

it enables the measurement of small or anti-reflex coated samples;

simultaneous measurement in X and Y directions;

extremely fast measurement: 1-2 seconds;

high reproducibility of the measurement results irrespective of the operators qualification;

the measurement results can be stored and printed out;

existing autocollimators can be upgraded;
