Ultraviolet (UV) Dome Lens

Most optical glasses can effectively transmit visible and near-infrared light. However, in the near ultraviolet region, most glass absorbs light to some extent. If the optical system must transmit ultraviolet light, the most common materials are fused silica and fused silica. Some heavy flint optical glasses have a low transmittance in the dark blue wavelength range and have a slightly yellow appearance.

One of the characteristics of quartz glass is that it has high light transmittance for ultraviolet, visible, and infrared rays. Quartz glass made from ultra-pure silicon dioxide (SiO2) as raw material has a total metal element content of only 1% × 10-6, therefore the UV transmittance is the highest, especially for shortwave UV; The wavelength of 180nm has a transmittance of up to 80%, and the wavelength of 190nm has a transmittance of up to 90%, making it an ideal ultraviolet material.
