Iridian's proprietary design and deposition technologies result in optical filters and thin film coatings that outperform others in the industry. Our energetic deposition systems are used to fabricate thin films that are dense, robust and have relatively low stress levels. The resulting thin film filters have physical and optical properties that are ideally suited to the most demanding filter applications.

In fluorescence analyses, it is essential that the light source be segregated from the emitted spectrum from the fluorophore so as not to interfere with the analyses.
Fluorescence Emission Filters
Fluorescence analysis of bio-medical samples requires optical filters that can detect the emission of photons after a molecule has been excited.
Fluorescence analysis of bio-medical samples involves the use of light at a particular wavelength to excite a molecule to a higher level of vibrational energy.
Gain Flattening Filter (GFFs), also known as gain equalizing filters, are used to flatten or smooth out unequal signal intensities over a specified wavelength range.
Linear transmittance filters are used for wavelength identification applications, employing a transmittance that changes linearly over a specified wavelength range.
Any standard product from Iridian's extensive line of thin film optical filters and coatings can be customized to suit unique needs and specifications.
Solid Etalon Filters have a well-defined periodically spaced frequency grid and are typically used for wavelength locking or dispersion compensation (all-pass filters).
Stray Light Absorbers (also known as "black" absorbers or beam dump filters) are used to reduce stray light in instruments by essentially absorbing all the light incident upon them over a given wavelength range.
Wide band pass filters are used to pass one or more very wide wavelength ranges - these filters are typically use to pass a selected set of widely spaced wavelength channels
