In order to achieved a desired optical functionality in an application, it is critical that key use parameters are communicated. Understanding the filter function and use conditions allows the filter design team to create a filter specification that will ensure the...
Filter specs vs Functional specs – the pitfall of double margining
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...
How Premium GFFs Improve EDFA Performance And Optimize Module Design
Iridian’s premium GFFs deliver higher-level performance than traditional GFFs to meet stringent PPEF specifications, as well as provide additional functionality. By Xiaolun Zeng and Michelle Derouin, Iridian Spectral Technologies Gain flattening filters (GFFs), used...
Optical Filters for Remote Sensing: Live from SPIE DCS2022
In this video from SPIE DCS2022 Jason Palidwar (Product Group Manager – Aerospace and Specialty Optics) discusses Iridian’s optical filters for remote sensing including earth observation (EO), IR gas sensing, and LiDAR and how these filters provide “More Signal and Less Background” to our customers’ instruments and systems.
