Key Features
Autocollimator mounted on stand with swivel arm
Accurate manual fine adjustment with arcsec sensitivity
Stand with hand wheel for convenient swivelling and a scale helping to find the angular position
Second autocollimator for transmission measurements in ground plate
Measurement times of less than one second per sample with pass/fail information
Measurement in reflection for outer prism angles
Measurement in transmission for internal deviation angles
Tilt and rotary sample table with height adjustment for different sample sizes
Sample table comes with three different interchangeable three ball supports
Applications
The Comparison Goniometer is used for angle measurements of any plano optics in production quantities with high speed and consistent accuracy:
any prism angles
wedge angle
90°-angle of prisms
measurement of small or antireflex coated samples
parallelism of plane plates
deviation angle through wedges and prisms
pentaprisms angle
mirror tilt
