- quartz waveplate
quartz waveplate and achromatic waveplate is made from different materials(crystal quartz and magnesium fluoride). Since the dispersion of the birefringence can be different for the two materials, it is possible to specify the retardation values at a wavelength range
- caf2 lens
caf2 lens exhibits good transmission from 150nm to 7.0 microns in the IR and is often used in cryo cooled thermal imagers.
- calcium fluoride lens
Calcium Fluoride exhibits good transmission from 150nm to 7.0 microns in the IR and is often used in cryo cooled thermal imagers.
It exhibits low absorption and has high damage thresholds making it suitable for excimer laser optics.
- calcium fluoride window
The calcium fluoride Window is made from calcium fluoride Window material, which has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. It has little hygroscopic susceptibility and high thermal expansion coefficient. The calcium fluoride Window is applicable for wide rang spectrum, and it is particularly useful for excimer laser application.
- Plano Concave Lens - Sapphire
The Plano Concave lenses are made from Sapphire material, which are manufactured with one concave surface and one plane surface. These lenses have negative focal lengths. These lenses diverge collimated incident light. They form virtual images which are seen through the lens. They are often used to expand light or to increase focal lengths in existing systems.
- Plano Convex Lens - Sapphire
The Plano Convex Lenses are made from BK7 material. It presents a curved interface and a planar interface. They are for instance the microlenses situated on top of a wafer, but can also encountered in macroscopic optical systems
- BBO Crystal
BBO Crystal is also an excellent crystal to be applied to frequency-double,-triple and -quadruple the high power acousto-optic and electro-optic Q-swithced and mode-locked Nd:YAG and Nd:YLF laser. More than 4W U V output at 355 nm and 2W output at 266 nm are stably generated.Udiing specially designed optical system,conversion efficiency>50% is obtainded for frequency doubling 532nm.In addition ,greater angle-cut BBO Crystal in an external resonant cavity,the Deltatrain ,an all-solid state laser system made by LAS Laser Analytical Systems GmbH.
- Sapphire
Sapphire is one of the two gem varieties of corundum, the other being the red ruby. Although blue is the most well known hue, sapphire is any color of corundum except red. Sapphire may also be colorless, and it also occurs in the non-spectral shades gray and black.
- Quartz Waveplate
Waveplates (retardation plates or phase shifters) are made from materials which exhibit birefringence.The velocities of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices.This difference in velocities gives rise to a phase difference when the two beams recombine.
