optimum silicon carbide lens

Ultraviolet - Wikipedia

Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency of approximately 30 PHz) to 400 nm (750 THz), shorter than that of visible light but longer than X-rays.UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.
