The Bed is heavy cast iron with a strong control rib, throughly seasoned and aged before machining and grinding of its upper surfaces. Total length 180cm with a machined full length platform for the scale. The scale is from lifetime stainless steel fitted on its machined platform on the bed. Divided in mms to a length of 170cm. Accuracy of calibration ± 0.01%

The Carriages:
Five carriages are provided to carry the standard experiement accessories. Under surfaces of carriages are machine true to fit the machined bed surface, and these machined surfaces are then jointly inter ground to give perfectly smooth sliding surfaces. While inter ground tests are carried out to ensure elimination of lateral shift during slide movements. Stainless Steel verniers fitted to the carriages read the scale of .01cm. The Bi-prism carriage is also provided with fine cross motion read by vernier to 0.01cm. Clamping arrangement is provided.

The standard experimental accessories fitted to the carriage are:

(i) Optical Slit : Manupulation of jaw movement free from any spring control ensuring maintenance of original accuracy even after prolongeduse . The following adjustments are provided for the slit And its carriage.

a) Linear adjustment along the bed, read by vernier to 0.01cm.
b) Fine vertical adjustment by slow motion screw.

(ii) Bi-prism Holder : Provided with following adjustment:
a) Linear adjustment along the bed, read by vernier to .01cm
b) Fine vertical adjustment by slow motion screw.
c) Fine cross motion by micrometer screw read by Vernier to .01cm
d) Quick radial motion along the horizontal axis
e) Fine radial motion along the horizontal axis.

(iii) Micrometer Eye Piece: Provided with the following Adjustments
a. Quick linear adjustment along the bed read by vernier to.01 cm
b. Fine micrometer vertical adjustment
c. Micrometer cross motion of the Eye piece along a 30-0- 30 mm scale read on a micrometer head to .001 cm. Micrometer head fitted with anti back lash Device.

(iv) Auto Action Lens Holder : With automatic Spring action for equal opening and closing of both sides. Rest specifications of carriage are same as above.
