PRODUCT:  KRS-5

                                                                                 

Introduction:

Thallium bromo-iodide(KRS-5) crystal, is mixed by thallium bromide and thallium iodide crystals, with non hygroscopic property, and has a wide infrared transmission range, especially in the air it can transmit quite wide infrared wavelength range, at 0.5~40μm area, its transmission can reach above 70%, it is a kind of excellent infrared material。


Applications:

It is a perfect material for making infrared optical windows, prisms, lens, Fourier infrared spectrometer window etc.,
