Product Description


Product Code : AB241

RESEARCH OPTICAL BENCH:


The Bed is a heavy cast iron with a strong central rib, thoroughly seasoned and aged before machining and grinding of its upper surface. Total length 180cms; 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 170cms. Accuracy of calibration # 0.01%.

THE CARRIAGE: Four carriages are provided to carry the standard experimental accessories. Under- surfaces of carriages are machined true to fit the machined bed surface, and these machined surfaces are then jointly interground to give perfectly smooth sliding surfaces. While inter-ground tests are surfaces are then jointly interground to give perfectly smooth sliding surfaces.

While inter-ground tests are carried out to ensure elimination of lateral shift during slide movements. Stainless verniers fitted to the carriages read the scale to.01cm. The Biprism carriage is also provided with fine cross motion read by vernier to.01cm. Clamping arrangement is provided.

(a) OPTICAL SLIT: With finely ground stainless jaws, oil-ground & optically tested. Manipulation of jaw movement free from any spring control ensuring maintenance of original accuracy even after prolonged use. The following adjustments are provided for the slit and its carriage.

  • a) Linear adjustment along the bed, read by vernier to .01cm
  • b) Fine vertical adjustment by slow motion screw.

(b) BIPRISM HOLDER: Provided with the following adjustments:-

  • 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.

MICROMETER EYE PIECE: Provided with following adjustment:-


  • a) Quick linear adjustment along the bed read by vernier to.01cm.
  • b) Fine micrometer vertical adjustment
  • c) Micrometers cross motion of Eyepiece along a 30-0-30mm scale read on a micrometer head to.001cm. Micrometer head fitted with anti-back-lash device.
