Being specialized in production of material of our Synthetic Optical Crystals which have fine grain, good for lenses, leave everything in our hands.

CaF2  
 

The single CaF2 (Calcium Fluoride) crystal has the superior features such as the wide transmittable wavelengths from 0.15µm-10µm, the low refractive index, the low dispersion and the unique optical dispersion (Abbe's number: 95). Also due to chemically and physically stable crystal with excellent waterÅAchemical and heat resistance characteristics, it can be used as lenses, windows and prisms for application in the wide wavelengths, from the ultraviolet to the infrared region.


MgF2  
 

The single MgF2 (Magnesium Fluoride) crystal having the transmittable wavelengths from 0.11žm to 7.5žm is mechanically stronger than CaF2. It is used as lenses, windows and prisms for application in the wide range of wavelengths from the ultraviolet to the infrared region. Also you can specify the axes.


BaF2 Now under trial production
 

The single BaF2 (Barium Fluoride) crystal having the wide range of wavelengths from 0.15µm to15µm, is much superior than CaF2 in infrared region. It is used as lenses, windows, and prisms for appliation in the wide wavelengths from ultraviolet to infrared region. Do not cool or heat suddenly since it is weak against heat shock.



Others  
 

Also LiF, CeF3, SrF2, LaF3, CaF2(Eu), BK7 Lenses, Synthetic Quartz Lens and others are available. Contact us for detail.
