OverviewThe 6B-LED and 6D-LED autocollimators are manual, high-precision optical instruments for non-contact angular measurement and alignment verification. The 6B-LED produces a bright-field image behind the reticle; the 6D-LED provides a dark-field image for higher contrast and reduced sample glare. Both models support rapid, repeatable checks of straightness, flatness, small angular deviations and rotational accuracy.
Applications- Verification of linear alignment and straightness
- Detection and quantification of small angular deviations and runout
- Measurement of convex and concave curvature and calculation of radius of curvature
- Assessment of component flatness and surface comparison against reference flats
- Measurement of feature heights and rotational accuracy of rotary tables and dividing heads
- Comparator checks and deflection measurement on parts with very small movements
Product highlights- Two models: 6B-LED (bright-field) and 6D-LED (dark-field) to suit sample contrast and glare conditions
- Brightfield or darkfield contrast enables simultaneous two-axis measurements for fast alignment
- Large adjustment ring corrects image curvature and enables quantification of curvature radius
- Retrofit LED illuminator unit available for improved illumination control
- Fast, repeatable operation with high angular resolution for industrial inspection tasks
