Penta Prism

Penta Prism is a five-sided prism containing two reflecting surfaces at 45° to each other, and two refracting faces perpendicular to the entering and emerging beams.


Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).It's a negative uniaxial crystal and mostly used as visible and near IR polarizers. It has high birefringence,..

Borofloat Windows

We can make kinds of Optical Windows from Borosilicate Glass, Borofloat, Quartz (Fused silica) and other Chinese substitution materials. This borofloat window can bear high or low temperature impact very well.

Beamsplitter Plate

The common Beam splitters are used to split or combine laser beam. However Polarization Beamsplitters are used to split or combine two perpendicular polarization laser beam.

Plano-Concave Lens

Plano concave Lenses have one concave surface. It has negative focal length. It is often used to expand light or to increase focal length in existing systems.

Rochon Polarizer

Rochon polarizer is one of the earliest designs, which is made of two birefringent material prisms cemented together. Both ordinary and extraordinary beams propagate collinearly down the optic axis in...

In optical second-harmonic generation coherent optical radiation of frequency 2ω is generated, through the use of a medium with the appropriate nonlinear susceptibility, from incident coherent optical radiation of frequency ω. For the process to take place efficiently, the phase matching condition (colinear geometry) k(2ω)=2k(ω) k(2ω)=2k(ω) must be fulfilled, where k(ω)and k(2ω)are the wave numbers, […]
