METHOD OF MANUFACTURING SINGLE LAYER INTERFERENTIAL OPTICAL FILTER Russian patent published in 2001 - IPC

FIELD: optical interferential spectral, more particularly quantum electronics, spectroscopy, and the like. SUBSTANCE: thin layer of amorphous material with refractive index n is disposed between two substates, substrates with material are heated to softening temperature of layer material and are simultaneously compressed over surfaces thereof, compression being carried out till optical layer thickness becomes multiple to kλ/4 wherein k is 2,4,8. During compression of substrates, one plate is simultaneously turned through reversible relative to other plate. EFFECT: simplified technology of manufacture of and improved quality of the tilter. 2 cl
