Introduction:
CASTECH offers windows either in multitudious substrates (Optical glass, Fused Silica, CaF2, BaF2, Ge, Si, ZnSe) or coated parts with multiple anti-reflection coating options covering wavelength range of Ultraviolet (UV), visible, or Infrared (IR). Millions of stock and custom precision windows are manufactured by different processing methods such as double-sided polishing, conventional polishing and ion beam figure(IBF) to guaranty high surface figure, low scatter, and high laser damage threshold to satisfy even the most demanding requirements.
Features:
- Material from DUV to FIR
- Custom dimensions and shapes
- Diameter from 0.5 to 600 mm
- Flatness: λ/10@632.8nm ( λ/40 by IBF)
- Standard and custom AR coating options available
- High laser damage threshold
