Angle Dekkor By Zesco India

Angle dekkor having a two axis graticule Micro optic and manual operated Should be provided with dark field graticule Allows to have a clear image from low reflectivity surfaces and from surfaces as small as 3mm. Direct Reading to 60 secs ...

Details:
It contains a small illuminated scale in the focal plane of the objective lens. (Collimating Lens)
This Scale is normal Position is outside the view of microscope.
The illuminated Scale project as parallel beam by the
collimating lens in the field of view of eye piece.
In the field of view of microscope there will another scale fixed across the centre of screen and reflected image of the illumined scale is received at right angle to the fixed scale.
Two scale in position will intersect with each other.
Thus the reading on the illuminated scale measures the angular deviations from 90 degree to optical axis and the reading on the fixed datum scale measures the deviation.
