Optical components

FOCUS Inc. is primarily active in the production of precision optical components of any type. Optical components made by FOCUS Inc. meet the following specifications:

·       spherical lenses (planoconvex, planoconcave, biconvex, biconcave, positive and negative meniscus)

·       spherical achromatic lenses - double or triple cemented lenses (planoconvex, planoconcave, biconvex, biconcave, positive and negative meniscus)

·       ball lenses

·       cylindrical lenses

·       optical flats, plan-parallel plates and high precision interferometric plates

·       optical windows

·       precision prisms of various types (rectangular, Dove, unilateral, Littrow etc.) and diffraction gratings substrates

·       colour filters, neutral density filters, interference filters

·       mirrors (plane, spherical concave, spherical convex, cylindrical concave, cylindrical convex etc.)

·       highly reflective (HR), antirefection (AR), dichroic, beamsplitter coatings

·       custom-designed optical components

·       laser-optical components: high-energy laser mirrors, high energy output couplers, high-energy beamsplitters etc.

·       optical components made from certain types of crystals



We process the following optical materials:

·       Optical glasses (Russian-made, Schott, Ohara, Corning, Sumita. Hoya)

·       Sitall (Russian equivalent of Zerodur)

·       Silicon (Si)

·       CaF2

·       BaF2

·       MgF2

·       Fused silica (VIS, IR, UV)

·       GGG

·       Phosphate glasses for laser active elements

·       Laser garnets

·       Alexandrite

·       Crystalline quartz

·       GaAs

·       Colour filter glasses (Russian, Ukrainian, Schott)



Optical components made by FOCUS Inc. meet the following specifications:

·       Linear dimensions, mm

from 1 to 600

·       Linear dimension tolerance, mm

to 0.001

·       Surface quality (scratch/digs ratio)
