When signal light is very precious, any background light that reaches the detector of an optical system can greatly compromise signal-to-noise ratio. If the signal is low, then the background must be maintained at an even lower level, and so background light must be minimized. For instance, in a Raman analytical system only one in … Continue reading
In designing a filter solution, the filter manufacturer takes the values requested by the user and adds additional design margin to account for both functional effects (such as wavelength shift due to angle variation, thermal induced wavelength shift, etc.) and filter manufacturing effects (such as edge steepness, non-uniformity, wavelength targeting – see Iridian’s technical note … Continue reading

Optical filters produced by Iridian Spectral Technologies play a key role in earth observation. These filters enable space-based remote sensing cameras to distinguish specific spectral bands that provide unique insights to agriculture among other applications. Read more about this topic in an article written by Panagiotis Vergyris, Ph.D. entitled “Photonics applications emerge for agriculture,” appearing the latest issue … Continue reading
To achieve a desired optical functionality for an application, it is critical that key use parameters are well defined when specifying the filter. Understanding the filter function and use conditions enables the filter design team to create a filter that both meets the functional requirements as well as the commercial constraints (cost, lead-time, volume) of … Continue reading
In this video from SPIE DCS2022, Jason Palidwar (Product Group Manager – Aerospace and Specialty Optics of Iridian Spectral Technologies) discusses Iridian’s optical filters for remote sensing. These include components for earth observation (EO), IR gas sensing, and LiDAR. This video discusses how these filters provide “More Signal and Less Background” to customers’ instruments and … Continue reading
