Fused Silica Precision Discs

UV-Fused-Silica-Windows-precision-custom-500x250.jpg

Newcastle Optics supply precision UV Fused Silica windows and flats. Fused Silica is ideal for precision optical flat windows due to its low co-efficient thermal expansion, low refractive index of refraction and high transmission. Used for laser and precision instrumentation they are custom AR coated for the UV ultraviolet to infrared regions.

Custom optical coatings are provided and AR coatings for laser windows, for the power density of your beam to a precise laser damage threshold specification. The windows can be supplied with interferometer graphs from our metrology department using the latest tri-optics software.
