UVB is generally defined as the wavelength range from 290-320nm, but it is the range between 290-305 nm that is most important.
Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8-12 µm wavelength range.
The additional lens may be made from a material or material system that transmits and focuses both the first band of wavelengths and the second band of wavelengths.
In some cases, the lens system includes a first region for focusing a first band of wavelengths onto a focal plane, and a second region for focusing a second band of wavelengths onto the same focal plane.
Likewise, the second region may or may not focus the first band of wavelengths onto the focal plane, and in some cases, may or may not even transmit the first band of wavelengths onto the focal plane, but this is not required.
