RANGE OF EXPERIMENTS TO BE CARRIED OUT :
- To measure the small angular difference of the object by using angle decker .
TECHNICAL DESCRIPTION :
This is also a type of an autocollimator. It contains a small illuminated scale in the focal plane of the objective lens (collimating lens).This scale in normal position is outside the view of the microscope eyepiece. The illuminated scale is projected as a parallel beam by the collimating lens which after striking a reflector below the instrument is refocused by the lens in the field of view of the eye-piece. In the field of view of microscope there is another datum scale fixed across the centre of screen and the reflected image of the illuminated scale is received at right angle to this fixed scale and the two scales, in this position intersect each other. Thus the reading on the illuminated scale measures angular deviations from one axis at 90° to the optical axis and the reading on the fixed datum scale measures the deviation about an axis mutually perpendicular to the other two.
