Optical Hexagonal Prisms (Light Guides)

The light guide uses total internal reflection theory, which can replace the non-uniform light source with a uniform light source regardless of its spectral characteristics. Compared with the square structure light pipe, the hexagonal structure light pipe can reduce the light loss by 30% - 40%. Light sources with small numerical aperture (NA) values require longer light pipes to homogenize the light, while light sources with high numerical aperture (NA) values may use shorter light pipes is enough.

Deflecting Optical Prisms

Deflecting prisms can

1) Change the direction of the original light path

2) Meet different special mechanical structure design

3) Achieve minimum spacing

Roof Prisms

Roof prisms can be used in applications that require deflection of an image or laser beam by 90 degrees. When passing through the prism, the image is reflected from right to left and top to bottom. The hypotenuse of the prism utilizes total internal reflection (TIR) to reflect the image passing through the prism.

90° Anti-reflective Coating Light guides

The light guide uses total internal reflection theory, which can replace the non-uniform light source with a uniform light source. 90° transmissive light guides are designed for applications that require uniform light distribution. Available materials and coatings will be selected according to different spectral requirements.

TIR Prisms

Small-sized TIR prisms are a kind of cemented optical prisms with three optical parts, and one of them is a spherical lens. It is difficult and crucial to glue and grind the air layer, but we make it competitive. It is used for small projectors, micro projectors like oral-scanner etc.

Right Angle Prisms

Right angle prisms can be used as 90° mirrors due to total internal reflection (TIR). When light is incident from one right-angled face of the prism, the light undergoes total internal reflection at the glass-air interface of the inclined face and exits the other right-angled face. Right angle prisms can deflect incident light by 90°, thereby replacing mirrors. Right angle prisms can also be used as 180° retroreflectors. When the input light is incident from the inclined face of the prism, the light will undergo total internal reflection at the glass/air interface of the right-angle face. A second total internal reflection occurs when passing through the next right-angle surface, and finally emerges from the inclined surface in a direction parallel to the incident beam. As with retroreflectors, the 180° deflection of the optical path is independent of the angle of incidence.
