Research Optical Bench

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.
