Precision Optics 

We produce and manufacture customized high precision optical components including high precision windows, prisms and other related products The materials are the Magnet Optic Glass, BK7, Quartz glass, other optical glass and crystal.

Optical prisms
Optical prisms are blocks of optical material with flat, polished sides that are arranged at precisely controlled angles to one another. They are used in optical systems to deflect or redirect beams of light. They can invert or rotate images, disperse light into component wavelengths, and separate states of polarization. There are several basic types of optical prisms.

Right Angle Prism
Right Angle Prism
Right Angle Prism 
Rectangular prisms are used to deflect a beam of light through 90 or 180 degrees. This can be used as component to create various optical devices. BK-7 can be used for a range between the visible and infrared light. fused-silica can be used for a range between ultraviolet and infrared light. We offer a wide range of different materials and different degree of precision prisms.
 Material: Glasses 
 Dimension Tolerance: ± 0.1 mm 
 Angle Tolerance: R < 30 arc seconds 
 Surface Flatness: λ/8 
 Surface Quality: 20-10 scratch-dig 
 Clear Aperture: 90% of edge dimension
Wedge Prism
Wedge Prism 
Wedge is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.
 Material: Glass 
 Dimension Tolerance: ± 0.2 mm 
 Wedge Angle Tolerance: ≤3 0 arc sec 
 Surface Flatness: ≤ λ/4 over the clear aperture 
 Surface Quality: 20-10 scratch and dig 
 Clear Aperture: > 90% of dimension 
 Chamfer: 0.25-0.5 mm
 Coating: Anti-reflection

 

* High Precision Window
High precision windows are used to isolate different physical environments while allowing light to pass relatively unimpeded. Window types available are plane windows and round windows. Common materials of construction for optical windows include BK7 glass, crown glass, calcium fluoride, germanium, sapphire, UV grade fused silica, and zinc selenide.
