Ultra Thin Substrates Specializes in ultra-thin optical substrates and wafers, including polishing 1" glass wafers down to 25 microns with a path toward 15 microns. Tight TTV and parallelism within a few microns enable high-precision optics for photonics, MEMS, and sensor applications.

End to End In-house capabilities span ingot slicing, coring, CNC shaping, and planetary lapping and polishing, delivering end-to-end production under one roof. This reduces lead times, supports consistent quality, and suits customers seeking a single-vendor source for custom optics.

Shape Flexibility Can handle non-standard substrate shapes beyond round wafers, such as squares, hexagons, and rectangles, opening opportunities for niche photonics, micro-optics, aerospace, and custom assemblies.

Quality and Delivery Strong emphasis on collaboration, responsive customer service, and on-time delivery backed by highly skilled, cross-trained craftsmen. Positions Mark Optics as a dependable supplier for defense, medical, and industrial instrumentation that depend on schedule and performance.

Strategic Partnerships As a small, agile Southern California manufacturer with growth potential, Mark Optics can pursue strategic partnerships, contract manufacturing, or white-label arrangements with larger optical OEMs and distributors to scale capacity, diversify customers, and expand market reach.
