Components

Spherical lenses

The main components of optical devices are spherical lenses - elements bounded by either two spherical surfaces, or spherical and flat surfaces. Spherical lenses are used to transform the shape of radiation beams and build images of objects.

Aspherical lenses & mirrors

It is possible to process axially symmetric and non-axially symmetric surfaces, Fresnel lenses and rasters, as well as surfaces whose shape is described by power polynomials (freeform). The maximum deviation of the aspherical surface from the best fit sphere can reach several millimeters. Surface control is carried out directly on the machine using an UltraComp profilometer with a sensitivity of at least 10 nm. The diameter of the processed surface is up to 200 mm.

Spherical and hyperhemispherical domes, cowls

Protective windows shaped as spherical domes are used to solve some specific problems. Usually, the domes are used in devices operating under high pressure, with high velocities of incoming air or liquid flows. According to their configuration, the hoods can be smaller than hemispheric, hemispheric and hyperhemispheric.

Cylindrical lenses

Cylindrical lenses are used to increase the viewing angle in one direction in anamorphic optics, to form a linear front of light propagation, to shape a beam of various types, to correct the astigmatism of the optical system, etc.

Wedge-shaped and plane-parallel windows and mirrors

Plane-parallel windows are used in optical devices as protective windows, light filter substrates, and compensators for spherical aberration. The use of wedge-shaped windows can be similar, and their specificity lies in the ability to deflect the beam and/or exclude the appearance of flare from the second surface.

High-precision processing of sapphire

Sapphire, due to its unique physical properties, can be used for the manufacture of optical products operating under extreme conditions, i.e. when exposed to high temperatures, pressures, mechanical loads, corrosive environments and radiation. For the successful application of such optical products, the quality of the polished surface is critical.
