Product Types
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.

Bandpass filters (BPF) are used to transmit one or more bands of wavelengths while blocking (or reflecting) adjacent wavelengths over extended ranges. |
|
|
|
|
Beamsplitter filters are typically used to split one beam into two beams through transmittance and reflectance. |
|
|
|
|
Coarse wavelength division multiplexing (CWDM) filters multiplex and de-multiplex wavelength signals in metropolitan networks, access networks, enterprise networks and cable networks. |
|
|
|
|
EPFs are used in telecommunications applications where wavelength band separation or optical add-drop multiplexing (OADM) is required. |
|
|
|
|
Tri-band optical filters are used for wave division multiplexing (WDM) in fiber to the home or business (FTTx) applications. |
|
|
|
|
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. |
|
|
|
|
Iridian offers a full range of multiple band pass filters in the visible and near IR wavelength ranging from 400nm-2500nm. |
|
|
|
|
Single Cavity Etalon Filters are narrow bandpass filters (typically with FWHM < 0.5 nm) that are well-suited for wavelength-locking applications |
|
|
|
|
Solid Etalon Filters have a well-defined periodically spaced frequency grid and are typically used for wavelength locking or dispersion compensation (all-pass filters). |
|
|
|
|
Bandpass filters (BPF) are used to transmit one or more bands of wavelengths while blocking (or reflecting) adjacent wavelengths over extended ranges. |
|
|
|
|
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 |
|
|
|
|
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. |
|
|
|
|
Optical edge pass filters (EPF) are needed to isolate transmitted wavelengths from blocked wavelengths often in a sharp transition. |
|
