Details
Optical crystals & glass, such as Quartz,
YVO4, Calcite, a-BBO, LiNbO3, Undoped YAG, Sapphire, CaF2, MgF2,
BK7, etc. are widely used in IR optics and UV optics. NEWPHOTONS
manufactures high transparency and low loss optical windows,
prisms, lenses and parallel planes by these optical materials.
NEWPHOTONS has strong capability in fabricating
optical components with various optical materials. The most
important material properties to consider for an optical element
are transmission versus wavelength, index of refraction, thermal
characteristics, mechanical and chemical characteristics and cost.
We also provide AR-coating and HR-coating for various optical
components.
To select the right materials seems overwhelming
important. We provides free services to select the right optical
components for your application.
