Kingsview Optical has extensive coating facilities covering all aspects of optical vacuum coating and optical thin films at our site in the UK. This includes multilayer broadband anti reflective coatings to full mirrors. The coating designs are done onsite using Essential Macleod design software which complements our other services such as optical design and mechanical design.
Types of Optical Coating
Multilayer Antireflecive – Custom designed to suit where high performance is required
Single layer anti-reflective – Cost effective magnesium fluoride coating
Mirrors – Including aluminium, chrome, silver and gold
Enhanced Mirrors – Dielectric enhanced where high performance is necessary
R&D Optical Coating
We have 4 different optical coating chambers the first 2 are smaller in size but very suitable for R&D coating runs where the numbers are low. Our Leybold 560 we use primarily for multi-layer anti reflective coatings. Our Edwards coats using thermal evaporation which we use to coat primarily mirrors and prism. We have the capability to coat most metals such as Aluminium, Silver, Gold and Chrome etc.
Production Optical Coating
Then we have 2 larger chambers where the majority of our work is put through. Both of these chambers are 900mm in diameter and are brought to vacuum using CTI on board cryo pumps and compressors. These chambers allow large numbers of parts in one firing so suitable for mass production with economical per part cost. In 2014 we updated our optical vacuum coating control system with a brand new Siemens PLC with custom code written for our application and a new E.B Gun power supply from Temescal. This has fully automated the process leading to more consistent coatings and layer stacks of up to 50 being routinely produced.
Full on site metalwork machining support which really helps when parts need custom coating jigs which really helps our delivery times and drives down costs.
With our dark room specifically developed for reticule production we can coat components and then in the next room produce reticules through photolithography with every stage manufactured in house.
