Dorsey 16H Horizontal Beam Optical Comparator

This ultra precision optical comparator utilizes an integrated zero backlash, high resolution scale and a free state, normalized zero stress stage. These features allow 16H optical comparator to attain inherent accuracy and repeatability values as high as .00001" without electronic compensation. This extremely accurate and versatile measurement instrument features our proven cast iron “ultra precision” stage system. Integrated fiber optic surface illumination, and an electronic rotary screen protractor combine to make this the most accurate and versatile horizontal benchtop optical comparator available at any price.
