Filter Processing Dicing Technician

Iridian Spectral Technologies manufactures high performance optical filters for a range of applications including telecommunications, bioscience, spectroscopy, space and entertainment. The filters are deposited onto glass substrates and cut into shapes as needed. The Dicing Technician will operate the dicing saws used for precision cutting of filters with rectangular shapes.

Applications Engineer/Physicist

The company currently has a vacancy in its group of Applications Engineers. The focus of the position is on the design, manufacture and performance of thin film optical filters.

Handheld Raman vs “Fingerprint” Applications and the Different Optical Filters that Enable Them

Raman spectroscopy is a powerful and increasingly ubiquitous analytical tool capable of identifying molecular constituents of samples under test and, when combined with microscopy, exploring specific cellular structures and functions. Non-invasive, non-contact, requiring no sample preparation or chemical tagging – it is no wonder that Raman has established a presence as an invaluable analytical technique both in labs and in the field.

The Application of WDM Channel Skip Filters

Channel skip filters are components added to wavelength division multiplexing (WDM) add/drop modules — in both coarse wavelength division multiplexing (CWDM) and dense wavelength division multiplexing (DWDM) applications — to facilitate band splitting and to manage multiple ITU channels.

These filters feature narrow transitions from pass band to blocking band, minimizing lost channels while maintaining high spectral efficiency (i.e., limiting insertion loss) since the express channels undergo only one reflection.
