Optical Windows

Witness samples allow testing without handling the actual part, to ensure the coating process is accurate before moving forward with the optical component. Read more...

ICC windows can reach high level precision like s/d 10-5; flatness 1/10l@633nm; parallelism less than 5min; bevel 0.1-0.25mm; Ra <1nm based on testing devices of ZyGO, AFM, 15sec gonimeter, and 2D imaging system. Here is our featured goods. Read more...

FTIR transmission windows - round,square,drilled, and customized. Transmission spectroscopy is one of the basic techniques for IR analysis. The sample and wavelength to be analysed determine the choice of window material, path length and window arrangement. Read more...

ICC's infrared material(Silicon,Germanium,ZnSe,BaF2,CaF2,MgF2,fused silica) bar comes out of the furnace with ICC factory's code. All components clean by ultrasonic after inspection, vacuum package perfectly.Share with email with related department much better! Welcome RFQ! Sample is available for you. Read more...

flame detector

Usually the most popluar material should be sapphire and ultraviolet fused silica, and some special security application need coated hard-AR/AR Germanium, optical silicon, and uncoated calcium fluoride window. Read more...
