Narrow Band Pass Infrared Filters
Narrow Band Pass (NBP) Infrared Filters are designed to isolate a narrow region of the infrared spectrum and are used in a variety of applications where precision detection of a specified wavelength is critical. Example of NBP IR Filter Spectral Transmission Graph Umicore has a wide range of off-the-shelf Infrared...
How do Infrared Filters work?
The emission of Infrared wavelengths occurs naturally at all times of the day and year. However it is ‘invisible’ light that spans a very broad spectrum, so to make practical use of IR radiation we need to somehow detect, control and manipulate it to provide coherent data. Think of a simple kitchen sieve. We put our vegetables into...
Markets & Applications
Infrared Filters can be used in a variety of applications and for a wide range of uses. Advances in technology and the expectation of an even more connected world, driven by the Internet of Things (IoT), Industrial Automation, Electrification of Vehicles, and Remote Monitoring of Preventive Safety Systems, have seen a rapid increase in...
