Question

Constructional difference between autocollimator and angle dekkor

Answer 1

Autocollimator:

• Projection and refraction of a parallel beam
• Change in direction with change in the incidence angle
• Used to check internal right angle
• Linear displacement is directly proportional to tilt of the reflector
• The focal length determines sensitivity
• Used for machine tool setting

Angle dekkor:

• A type of autocollimater
• The illuminated scale is projected as a parallel beam
• Not a precision measuring instrument
• Used to measure the angle of the component
• Used to configure angular settings for machinery
