Achromatic Lens Kits
For applications where multiple focal length doublet lenses may be needed, achromatic lens kits provide a convenient selection of equivalent diameter lenses from which to choose. Our achromatic lens kits are offered in one and two inch diameters.

Mirror
Broadband Dielectric Mirrors
These mirrors have the same exceptional specifications as our laser mirrors except that they use special multilayer coatings to achieve a very high degree of reflectance for both s- and p-polarizations over a broad wavelength range. For white light or tunable laser use these mirrors provide the ultimate in high reflectance and insignificant polarization effect.

Prism
Retro-Reflectors
Retro-reflectors, or corner cubes as they are sometimes called, have the property that light incident on the face of the prism is deviated by 180 degrees independently of its angle of incidence. This means that any light incident on the surface will be reflected back along the same path that it came from.

Beamsplitter
Laser Polarizing Cube Beamsplitters
These are thin film polarizers constructed as a cube. Thin film polarizers utilize the polarization which occurs on reflection from a plane surface. By combining a large number of such surfaces in a stack it is possible to obtain useful extinction ratios. The s-polarization is more than 99% reflected while the p-polarization can be suppressed in the reflected beam and become 95% transmitted. Thin film polarizers can be optimized for a particular wavelength to give superior performance for laser applications.
