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.

| Company | Product Description |
 Dowlish Ford Ilminster TA19 0PF United Kingdom |  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. |
