Product Description

SPECIFICATIONS OF FABRY-PEROTINTERFEROMETER

MECHANICAL PARTS

Lead screw dia.: 17 mm; Pitch: 1 mm;Threaded length: 200 mm 

Lead screw and its nut are optically lappedto maintain constancy for the pitch.  

Interferometer is provided by three scales.

Linear scale (0-150 mm graduated in mm) isattached with the left hand side of the bed of interferometer.

Graduated disc (0-100 div.) may be peepedthrough glass window provided with the head of the interferometer.  One division of graduated disc = 0.01 mm

A graduated slow motion drum (graduation0-100 div.) is fitted on right hand side of the interferometer.  One division of slow motion drum = 0.00001mm.

i.e. Least count of interferometer : 10-4 mm

 

OPTICAL PARTS :

 

Partially coated mirrors (2 Nos.) areheavily coated (metallic coating). Interference pattern formed by D1 & D2 lines of sodium are clearlyvisible even by naked eye.

 

Mirrors are made of optical glass havingstep, i.e., one face is of dia. 23 mm (which is coated face); other face is 27mm and Thickness 12 mm. 

 

Surface figure of coated face: Better than l/10

 

Mirrors reflectivity: @ 80% 

 

Coating material: Al. with protective coatof SiO2

 

SPECIFICATIONS OF TELESCOPE

 

Objective is an achromatic doublet of dia.25 mm and F.L.: 50 mm and Telescope magnification: 10x
