Ultraviolet light is light with a wavelength shorter than ≈ 400 nm, the lower limit of the visible wavelength range.
For handling UV light, special UV optics are required. Important material parameters for UV applications are a low bubble and inclusion content, good homogeneity of the refractive index, and the potential for polishing surfaces with very small roughness.
Some optical fibers can be used in the near-ultraviolet spectral region, although with relatively high propagation losses. Fiber delivery of ultraviolet light is usually not feasible for shorter wavelengths and/or high optical powers. Due to this limited reflectivity, Ultraviolet optics have to be designed with the smallest possible number of reflecting surfaces.
Proper manufacturing ultraviolet optics techniques and close attention to cleanliness are required to make the best UV optics possible. If improper grinding or polishing techniques are used, there is a potential for the substrate to have roughness and possible micro-fractures. The visual inspection of the substrate surfaces may look good, but when UV coatings are applied, a typical outcome is grazing or micro-fractures in the coating.
Laser Optics are optical components designed for use with lasers or within laser systems. Laser Optic manufacturing often feature damage thresholds that are compatible with certain laser types. Laser Optics utilize specific substrates, coatings, or a combination of the two to achieve high performance at designated laser wavelengths. Laser Optics includes optical components such as optical lenses, optical filters, optical windows, or mirrors that have been optimized for transmitting or reflecting lasers.
Laser Optics are utilized across automotive, commercial, medical and military industries.
PFG has specialized in manufacturing standard and custom laser optics for many generations. Optimized for all the most common laser systems including CO2, Fiber, PFG coating technology assures the highest damage thresholds and transmission. Laser optics include focusing lenses, high power and super flat mirrors, protective windows, output couplers, and high damage threshold coatings.
Manufacturing precision optics is a very precise business that involves computer-controlled polishing machines. While manufacturing processes have changed over the years and automation has largely replaced the traditional craftsman-style optician.
