55861 Experimental Set-up has been designed specifically to determine the wavelength of the laser using grating and to determine the slit width. The set-up consist of an Optical bench, Diode laser, Optical screen, Double convex lens, Slit, Diffractio...

SPECIFICATION

The set-up is complete in all respect and requires no other apparatus. Practical experience on this set-up carries great educative value for Science and Engineering Students.

OBJECT

To determine the Wavelength of the Laser using Grating.
To determine the Slit Width.

FEATURES

The Complete Experimental Set-up consists of the following :

OPTICAL BENCH : 100cm long steel rods ½” dia forming a bench with and supports having leveling screws. One of the two steel rods is graduated. It has four riders two with transverse motion & two fixed.
DIODE LASER WITH POWER SUPPLY.
- MAXIMUM OUTPUT : 0.5 mW
- WAVE LENGTH : About 670 nm visible red
- POWER SUPPLY : Included with ON/OFF switch working on 230 mains.
OPTICALSCREEN : about 10cm x 10cm with graph on it and can be fitted into rider.
DOUBLE CONVEX LENS: 50 mm dia & F.L. 10cm.
OPTICALSLIT : Optically true, precision ground stainless steel jaws. The jaws open uniformly all along through the milled head.
