Knight Optical’s Domes for Pyranometers

13 Nov 2020

Offering optimum protection for Pyranometer devices, our Optical Domes provide both high transmission and extreme endurance for devices subjected to harsh environments. As well as a range of stock, we also offer custom-made Optical Domes to meet the precise needs of each and every application.

 Here at Knight Optical, we have, and continue to work with many leading brands within the solar industry over our 28 years in business, and as a result, our Optical Domes have become the components of choice for engineers working on high-precision projects such as Pyranometers. This is partly thanks to the optical knowledge of our Technical Sales Advisers and our in-house capabilities in guiding our customers' projects from conception through to success with on-spec, long-lasting components for optimum performance.

 Our Optical Domes are available in a wide range of options to meet a diverse range of requirements. From the ultraviolet (UV) through to Infrared (IR) spectrum, our custom-made Optical Domes can be manufactured from a variety of substrates (including Sapphire) to meet your project's specified waveband. These material options include, but are not limited to, BK7 (or equivalent), or NBK10 for visible applications, UV Grade Fused Silica for UV applications, Silicon for 3-5 micron in the Mid-IR band and Germanium for 7-14 micron Longwave-IR band.
