At Alluxa, we are continually striving to improve our products by researching and developing novel thin-film technologies. Therefore, we welcome any custom optical filter requests for non-standard spectral shapes, unusual coating materials, tunable filters, extreme blocking, or any other challenging technical specifications.
Iridian Spectral Technologies offers LiDAR laser sensor systems with common laser wavelengths including 532 nm, 905 nm, 1064 nm, and 1550 nm. These filters provide more signal with less background and are ideal for laser sensor applications, including airborne laser scanning and other methods of capturing 3D data of large areas.
In astronomical observations, optical filters are able to provide the wavelength selectivity needed to enable telescopes to discriminate signal from background information. These filters often require larger sizes, higher uniformity, and excellent surface quality and surface figure.
Iridian offers over 20 years of experience in producing industry leading optical telecommunication and datacom filters for terrestrial systems. Commercial satcom networks will consist of constellations of 100’s to 1000’s of satellites in an interconnected low earth orbit (LEO) mesh. Many of these systems rely on an optical intersatellite link (OISL) architecture to connect satellites via laser based optical communications. Optical filters provide wavelength selectivity to these systems addressing different functional needs from solar rejection windows to beam steering wavelength selective dichroic filters.
DSI provides three specialized coating process technologies designed to accommodate the many demands placed on thin film coatings. Each process offers the ability to provide unique solutions, higher performance, increased volume, and much more durable coatings.
DSI offers its expertise on high quality testing capabilities for many types of resources such as in-house produced materials, as well as independent verification of external coated and uncoated samples for vendor/supplier surveillance, process analysis, and qualification testing. Each quality system is ISO 9001:2008 certified and ITAR registered and compliant. Environmental testing is also available and is performed in accordance with military specifications.
Abrisa Technologies offers a broad spectrum of glass machining services that can fit nearly every application-specific customer requirement. With CNC processing and other glass fabrication equipment, this company can manufacture a wide variety of glass parts ranging from simple to the most complex designs. Some of the offered processes performed in-house include notching, slotting, grooving, edge grinding, stepped surfaces, hole drilling, circle grinding, polishing, and sandblasting.
Acton Optics & Coatings offers bandpass, band rejection, long pass, neutral density, reflective, and solar blind filters for spectroscopy, elemental analysis, environmental monitoring, biotechnology instrumentation, space exploration, and in general research areas.

Discover The New Bandpass Filter BP 850-80 HT From Schneider-KreuznachSchneider-Kreuznach is pleased to present the new BP 850-80 HT infrared filter as an addition to its range of bandpass filters. This filter has been specially developed for applications with powerful infrared high-power LED’s (850nm), which are becoming increasingly popular. Cameras equipped with these LED’s can deliver night-time images up to 20-30 meters. The Schneider-Kreuznach infrared filter in combination with an 850nm LED light source produces strong and shadow-free infrared illumination that is visible to many sensors but invisible to the human eye. Therefore, it is perfectly suitable for the use in surveillance systems and industrial applications.

![1]( "What Are Thin-Film Optical Filters?")
What Are Thin-Film Optical Filters?Thin-film optical filters are made by depositing alternating thin layers of materials with special optical properties onto a substrate, such as optical-grade glass. As light makes its way through the optical filter, its direction changes as it passes from one layer to the next, resulting in internal interference.
