Wafer sizes range from 50mm diameter to 300mm diameter. Coating thicknesses range from 0.5 microns to 10 microns. A photoresist is a light-sensitive material used in several industrial processes, such as photolithography and photoengraving, to form a patterned coating on a surface. Blanket photoresist coatings may also be patterned per customer specifications. Coating thickness and […]

High Quality Apertures for Medical Endoscopes The smallest aperture size we’re able to resolve is about 2um. Typical substrates inclue N-BK7, B270, D263, fused silica, and sapphire, but we can use other specified material as well. Typical aperture coating utilizes our proprietary black chrome: Very durable, low reflecting in visible with Rave <5% , OD […]

Opto-Line International has been creating custom precision patterns on optics since 1967 We are not your standard, stock reticle company. Instead, Opto-Line manufactures your unique, custom patterns on optical substrates per your requirements. From reticles and apertures to multi-density resolution masks and almost any pattern imaginable, our photolithography and thin film coatings practices are optimized […]

For many years, Opto-Line has supplied high-end EMI grids on IR substrates, reticles, and custom patterned optics for defense systems including scopes, laser range finders, target designator systems and other critical applications.

Opto-Line’s team is highly experienced in crafting reticles, ellipses, metrology targets, and many other custom patterns for the Optometry & Opthamology industries. “We are realizing things that Opto-Line can do for us that we never even thought within our reach.” Alfredo Dubra Associate Professor of Ophthalmology, Stanford University
