Optical Thin Film Coating

Optical Thin Film Coating – PFG Optics

PFG Optics thin-film optics is the branch of optics that deals with very thin structured layers of different materials.In order to exhibit optical thin film coating, the thickness of the layers of material must be on the order of the wavelengths of visible light. Layers at Optical Thin Film Coatingthis scale can have remarkable reflective properties due to light wave interference and the difference in refractive index between the layers, the air, and the substrate. These effects alter the way the optic reflects and transmits light. This effect, known as thin-film interference, is observable in soap bubbles and oil slicks.

In manufacturing, thin film layers can be achieved through the deposition of one or more thin layers of material onto a substrate (mostly glass). This is most often done using a physical vapor deposition process, such as evaporation or sputter deposition, or a chemical process such as chemical vapor deposition.

Thin films are used to create optical thin film coating.

Laser Optics Manufacturing – production of high quality precision optics

Laser Optics are optical components designed for use with lasers or within laser systems. Laser Optics manufacturing often feature damage thresholds that are compatible with certain laser types. Laser Optics ManufacturingLaser 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.

UV Optics – Manufacturing Ultraviolet Optics

Ultraviolet light is light with a wavelength shorter than ≈ 400 nm, the lower limit of the visible wavelength range.UV Optics Manufacturing

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.
