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
Raman spectroscopy is an analytical method based on the detection of scattered light from a sample. Only a small fraction of scattered light is suitable for Raman spectroscopy — around 1 in 10 million incident photons induce a Raman scattered photon. Generating enough scattered photons for Raman spectroscopy purposes requires a high intensity light source. … Continue reading
To conduct data analysis of nucleic acid samples, typically DNA, a reasonable amount of DNA material is essential. Today’s standard approach is to replicate very small samples of specific DNA to obtain sufficient quantities that allow detection or identification, for example in biomedical or forensic laboratories. The common method is the polymerase chain reaction (PCR). … Continue reading
Iridian Spectral Technologies proudly announces that their article “Optical Filters Enhance PCR-Based Detection of COVID-19” is the cover story in the latest issue (January/February 2022) of BioPhotonics. Wavelength-specific filters help to separate fluorescence and excitation light, resulting in less background noise, which facilitates accurate results in real time. The optical filters providing the wavelength selectivity … Continue reading
