Large Optics (100mm+)

Struggling to find large diameter lenses?

We've got them. Specializing in hard-to-find optical elements, Ross Optical offers one of the biggest selections of standard large lenses, 100 mm in diameter and above.

Large diameter optics are critical for precision instruments such as telescopes and imagers, but very few companies today carry these elements. Ross Optical sources achromats, plano convex lenses, and a wide range of other large optics through a reliable global network of optical manufacturers. We also provide inventory solutions including JIT delivery and vendor-managed inventory. 

Not seeing the part you need? We can create a custom lens or assembly to meet your requirements. We can also perform custom optical coatings for large lenses, including anti-reflection, V-coating, Rmax, and beam splitters.
