Calcium fluoride (CaF2) crystals have a wide transmittance range (within 0.13 μ M~10 μ It has the advantages of good transparency within the wavelength range of m, low stress birefringence (no obvious intrinsic birefringence above 200nm), uniform refractive index, stable mechanical properties, no deliquescence, and strong resistance to radiation damage. It is an ideal material for making various optical windows, prisms, lenses, and other optical components.
Attention:
The hole spacing for punching holes on 30mm and 32mm diameter window panels is 19mm, with an aperture of 1.8mm; The hole spacing for drilling 41x23x4 rectangular window panels is 30.5mm, and the aperture is 1.8mm.
