      Product Description

      Constant Deviation Spectrograph ( C.D.S ) HLSI

      Description :

      Collimating Tube : ( material : Brass Pipe ) O.D: 50 mm I.D,: 44 mm for fitting collimating lens. It is provided with rack & pinion arrangement and slit.

      Slit is of circular type.

      The jaws of the slit are optically ground.

      It is provided with Holfmanns Diaphragm.

      Telescope Tube :  ( Material : Brass Pipe) O.D,: 50 mm, I.D,: 44 mm for fitting telescope lens.

      It is provided with rack & pinion arrangement for proper focusing of spectral lines.

      Eyepiece: (Ramsden Type) : magnification : 10 x

      In eyepiece holder a conical pointer is fitted in the focal plane of eyepiece.

      Corrected achromatic doublet are fitted in the lens holders of collimator and telescope tube.

      Double dia : 44 mm, F.L: 350 mm (14).

      The Collimator and telescope tubes are fitted in cast iron blocks which are mounted on a machined cast iron blocks which in turn are mounted on a machined cast iron plate.

      Suitable gap  is provided between collimating lens and prism table to accommodate high resolving instrument like Fabry- Perot Etalon.

      Prism Table is fitted on the machined cast iron plate and actuated bt tangent screw to provide smooth rotation of the C.D.S. prism placed on it.

      Prism Table is covered with a box of a aluminium casting having two gates.

      One gates allows light coming from collimator to enter into C.D.S. prism.

      Another gate allows light to be collected by telescopic objective after light being dispersed from C.D.S. prim.

      A calibrated drum  (Calibrated for visible region i.e.from 4000 A-7000 A) is attached with the prism table assembly.

      Accuracy of calibration 5 A
