Technical Specification
FEATURES :-
The Complete Experimental Set-up consists of the following :
01 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.
02 LASER DIODE WITH POWER SUPPLY. MAXIMUM OUTPUT : 0.5 mW WAVE LENGTH : About 670 nm visible red
POWER SUPPLY : Included with ON/OFF switch working on 230VAC ±10% AT 50Hz.
03 OPTICAL SCREEN : about 10.25” x 5.5” with graph on it and can be fitted into rider.
04 DOUBLE CONVEX LENS : 50 mm dia & F.L. 10cm.
05 OPTICAL SLIT : Optically true, precision ground stainless steel jaws. The jaws open uniformly all along through the milled head.
06 DIFFRACTION GRATING: Hilger & Watts Type, 15000 line per inch/6000 lines per cm.
07 LENS HOLDER : FOR DIFFRACTION GRATING
