This is the 475-35 EX, a 25 mm diameter mounted excitation fluorescence bandpass filter, with a thickness of 3mm, manufactured by Iridian Spectral Technologies. The filter is designed to transmit light within a specific range of wavelengths, making it ideal for various applications in photonics, spectroscopy, and imaging.
The 475-35 EX filter is a bandpass filter, a type of optical filter that only allows light within a specific range of wavelengths to pass through. The cut-on wavelength is 457.5nm, and the cut-off wavelength is 492.5nm, with a central wavelength (CWL) of 475nm. This means that the filter will allow light between these wavelengths to pass through while blocking other wavelengths.
The filter is made of UVFS MAL-1965 material and has a circular base shape. It features a thin lens shape and is coated with IRI 475-35-EX on both the front and back surfaces. The catalog number for this filter is 475-35 EX, and it is currently in stock, as indicated by its valid weblink status.
