Cutoff Filter - A filter that does not pass light of wavelengths shorter that the cutoff wavelength and passes a wide band of wavelengths above the cutoff wavelength. The cutoff wavelength is specified at some point along the transition from maximum transmission to 0 transmission. The same filter can have different cutoff wavelengths depending upon the specified % transmission. The same filter may be specified as a 500nm cutoff filter with the 50% transmission point as the reference or a 485nm cutoff filter if the specification is the 5% transmission point, where the transmission at 485nm is 5%.

manufactures, develops and markets a variety of synthetical
crystals to meet different scientific and industrial needs...
• Crystal Growth
The Czochralski crystal growth method
is the method that is used to produce the majority of commercially available single crystals.
This method yields fairly large crystals with low defect concentrations...
• Crystal Growth
Flux method (growth from high temperature solutions) is the
method that is used to the growth of single crystals of incongruently
melting compounds...
• Fabrication
After removal from the growth station, the crystal is cut, the ends are polished, and the defect-free region of low stress are carefully mapped using interferometer ...
