Gooch & Housego 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.
Superpolished substrates feature surface roughness lower than 1 Å, scratch/dig <5/2, and inspection upwards of 320x 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.
In keeping with the high standards of our superpolished surfaces, most of our optics are supplied with polished or acid etched diameters or bevels. These extra touches add to the level of cleanliness and durability that can be achieved.
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.
