IR blanks are used in night vision and thermal imaging solutions for imaging, defense and industrial monitoring equipment. We mainly process silicon and germanium. We have professional skill in processing optical infrared blanks by CNC machining and generating capabilities.
Luoyang Silicon is a factory only for Silicon and Germanium. We have 10 years experience.
Growing the silicon ingot, we can control the ingot quality, to achieve better transmittance for MWIR 3um-5um
