UV to IR lenses are available in all shapes and sizes that can be found in other categories, but they are specifically optimized for each wavelengths range. For UV lenses to reach good imaging properties for shorter wavelengths a selection of materials are used like fused silica or CaF2. In visible spectrum from 400 to 700 nm wavelengths materials fused silica, N-BK7 or other SCHOTT standard glasses. For IR spectrum Solaris Optics usually uses fused silica, Si or Ge.
To further improve the quality of lenses, dedicated coatings are applied that can reduce reflection in working wavelength range or transmission in undesirable spectrum.
The applications for ultraviolet optics are very broad and include laser optics, fluorescence detection and various diagnostic tools in medicine, biology, art and archaeology.The applications for VIS lenses include any optical devices relying on the human vision that don’t implement any intermediate digital modifications to light (microscopes, spectacles, telescopes). The applications for infrared optics are very broad and include thermal imaging, infrared spectroscopy, and remote sensing. The near infrared spectrum (NIR) is also used in photography and surveillance.
