Our Resolution Test Targets Meet all MIL Standards Still widely used as an accepted method to test the resolution of optical imaging systems including microscopes, cameras and image scanners, resolution test targets are a specialty of Opto-Line. For more information about how we can help meet your test target needs, we invite you to call […]

Specializing in custom precision optical patterns for all areas of research and development, Opto-Line helps clients reach their R&D goals. Our custom patterns are often vital components in the R&D phase of a product. We have a long history of partnering with companies across an array of industries to help them achieve their product goals. […]

Our durable black chrome has a Rave <5% over the visible spectrum and has been a tried-and-true coating for decades. But it is not only the coating that separates Opto-Line from other companies but the precision we can accomplish in the detailed patterns. Please contact us to find out how we can partner with you […]

Opto-Line patterns on a myriad of substrates including all glass material and other IR materials including geranium, silicon, zinc sulfide, quartz, and sapphire. The largest substrate size that Opto-Line can pattern is approximately 12.5” diagonal. The smallest part that can be manufactured is about 1mm x 1mm.

Opto-Line International Creating Custom Precision Patterns on Optics Since 1967 Opto-Line is not your standard, stock reticle company. We 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 to create your […]

Opto-Line uses the following methods for our customer’s custom Multi-Density Resolution Masks: Half Tone: By using very small dots and changing the amount of the dots, we can create varying densities that typically fulfill our customers’ needs. Continuous: Discrete, individual depositions of Inconel are used to create each density. In this case, Opto-Line requires separate […]

Reticles are a common type of pattern we handle, but they are just the beginning. Beam Splitters, slit apertures, 1951 resolution test targets, and everything in between can be made to our customers’ specifications. We’d love to hear from you. Please tell us more about your custom optical pattern needs.

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 […]
