Optical coating filters are unique or thinner layers of substantial put on a visual component such as a lens or mirror, altering how the optic reflects and transmits light. One category of optical coating is an anti-reflection coating, which decreases undesirable surface reflections and is typically used on spectacle and photographic lenses. Another kind is the high-reflector coating, which can yield mirrors that reflect greater than 99.99% of the light that falls on them. More complex visual coatings display high reflection over some range of wavelengths, and anti-reflection over another content, letting the assembly of dichroic thin-film optical filters.
There is a variety of optical coating equipment at its disposal, offering users solutions tailored to their precise applications. Technologies include:
- Ion-Assisted E-Beam deposition
- Magnetron Sputtering
- Resistance Evaporation
- Hybrid Technologies
The design and manufacturing of these optical coating filters meet your most challenging requirements. Series of Wavelengths from 193nm to 14 microns, on an extensive diversity of substrate materials including filter glass, BK-7, borosilicate glass, Silicon, Sapphire, Germanium, Fused Silica, Calcium Fluoride, Zinc Sulfide, Zinc Selenide, and more.
These filters are computer-controlled, internally custom-built, and have the latest deposition techniques. Ion beam compaction produces high-density coatings, decreasing environmental effects and removing voids in the layer, increasing hardness.
There is an extensive back-catalog of optical covering formulas for substrate things, from optical glass and crystalline materials to simple nickel-plated metals. Also, the thin-film coatings work with oxide and fluoride dielectric multilayer-coating materials, including SiO2, MgF, TaO5, and HfO2. It also compromises improved and protected metallic layers of silver, gold, and aluminum. Usually, the coating line-up covers an insignificant wavelength range from 193nm – 14µm.
