Alluxa

Alluxa was founded in California in 2007 by a group of experts with many years of experience in thin-film and measurement technologies. It is worth noting that the multiple identical coaters were designed and built in house; thus, this team of some 90 employees can perform at an optimum level that is achieved nowhere else. Each coater covers the entire production process. The combination of modern automation technology and online monitoring, algorithms developed in house, and patented plasma coating processes facilitate individual hard coating processes that allow reproducible results due to full automation.

Comprehensive control over the entire coating process is what distinguishes Alluxa from its competitors. The factory is vertically integrated to focus its efforts on the sole design and manufacture of optical filters; from chamber design & assembly, to software deposition programming, to optical metrology and post-coating fabrication  The result is a highly specialized, and focused, expertise which can tackle the most challenging of thin-film problems. Furthermore, chamber and process redundancy mitigate chamber to chamber variations and eliminate any risk associated with equipment downtime.

A specially developed series of flat-top ultra-narrow band filters with a FWHM of <0.1 nm demonstrates excellent transmission/blocking behavior. Typical transmissions lie above 92% in combination with a broadband deep blocking performance of up to OD6. This is all thanks to the monitoring system developed in house for formats of up to multiple of inch in diameter, which can be considered to be at the technological forefront.

Edge filters, notch filters with broadband transmission and low ripple, dichroic elements (upon request, even available with a planarity of <0.1 waves/1”), multiband filters, and custom job coatings in the UV to the IR are all an integral part of the spectrum.
