Catalog excerpts

An easy-to-use, precise metrology instrument for angularity, parallelism, perpendicularity, straightness of precision components, machine guide-way and many other applications. Nikon Autocollimator 6B-LED and 6D-LED both employ 70 mm aperture lenses to produce clear reflected images, ^ey also feature extremely accurate double line reticles for improved detection. Both give readings of angular displacement to 0.5 seconds of arc using an easy-to-read large-diameter micrometer drum. • Efficient measurement because the autocollimator needs only the setting of a target mirror and collects...

Bright & dark viewfield The Autocollimator 6B-LED is a bright viewfield instrument in which a black crosshair image is visible on a bright viewfield, while the Autocollimator 6D-LED is a dark viewfield instrument in which a bright crosshair image is visible on a dark viewfield. Autocollimator 6D-LED is very effective when measuring with a small plane mirror or a low-reflective plane surface. LED illuminator Both can operate on two AA batteries, enabling the instruments used in the environmentwhereAC power is not available. *No battery charging capability Case forAutocollimator Aluminum...

Check the angular accuracy of rotary tables Check the deflection of elastic or springy materials Check the parallelism of end surfaces Check the angle of work pieces Measure the accuracy of rotary tables or dividing heads using polygon mirrors. The octahedral mirror measures in units of 45°, and the dodecahedral mirror in units of 30°. Affix the mirror the specimen and read the angular deflection using the autocollimator. Small vibrations may also be detected in this manner. Compare the difference between the crosshair images reflected from the surface of the specimen and from a standard...
