Where to Buy Superpolished Optics

Optical elements are typically provided with relatively high optical quality, but there are superpolished components with unusually high quality, e.g. with sub-angstrom surface roughness.

superpolished optics

Shalom EO offers superpolished optical components with ultra-low surface roughness made from substrate materials including UV fused silica, BK7, sapphire, ZnSe, ZnS, germanium, silicon, CaF2, MgF2, YAG and others,in the forms of lenses, windows, mirrors and substrates.

Shalom EO developed an unique and low-cost processing for a classical polishing line, and a strict inspection system utilizing an Atomic Force Microscope (AFM) measuring system, Zygo interference flatness test instruments and critical coating testing in the process of manufacturing, resulting in a roughness <1 Å, together with high flatness, low scattering loss and low absorption and high surface quality. With such remarkable qualities, our products are suitable for applications ranging from DUV lasers, high power lasers to laser gyro systems. Custom optics with various dimensions and optional High Reflection (HR) coatings or Anti-Reflection (AR) coatings are also available.

superpolished optics

G&H has been producing superpolished surfaces for over 40 years and is the world’s original provider of superpolished optical components. We have evolved our proprietary process to handle high volume and specialized R & D requirements.

Typical applications are cavity enhanced absorption spectroscopy, ring laser gyroscopic systems, ultrafast laser research, and ultraviolet laser systems. Possible substrate materials are BK7, crystal quartz, fused silica, and Zerodur®.

Superpolished substrates feature surface roughness lower than 1 Å, scratch/dig <5/2, and inspection upwards of 320× magnification. The result is extremely low scatter, losses and defects – a requirement for any high performance laser application. The substrates offer an impressive 1/20th wave or better surface accuracy.

To complement our superpolished surfaces we offer ion beam sputtered (IBS) coatings which achieve very low levels of total loss (absorption and scatter), and exceptional environmental stability.

superpolished optics

Edmund Optics offers superpolished laser window substrates where both surfaces have <1 Å r.m.s. surface roughness. The low scatter surfaces are ideal for UV and high power laser applications. We use UV fused-silica substrates with polished bevels and edges. Our in-house manufacturing enables custom versions with dimensions from 6 mm to 76.2 mm and different shapes; the surface roughness can be even <0.5 Å.
