METHOD OF MAKING OPTICAL-MECHANICAL MODULE Russian patent published in 2010 - IPC G02B7/00 C03C27/04 

FIELD: physics.

SUBSTANCE: method of making an optical-mechanical module involves making a dimensional workpiece from optical material and a proportional rim from metal, preparation of joining surfaces, putting solder between joining surfaces of the workpiece and rim, positioning the workpiece and the rim using tools and subsequent indium soldering. Material of the optical element and the rim is selected from a list of materials with adhesion to indium. Joining surfaces of the workpiece and rim are prepared by polishing to a roughness value R_Z≤0.1 mcm. The joining surfaces of the workpiece and rim are heated to temperature higher than melting point of indium. Solder is smeared onto the surfaces and then cooled. The soldering process is carried out under pressure which facilitates compensation for reduction in volume of the solder during phase transition.

EFFECT: making optical devices based on permanent joints of optical materials with a metal rim with high strength, are resistant to vibration effects and work in a wide temperature range.
