The 39-349 is a Bandpass Filter with a 25 mm diameter, manufactured by Edmund Optics. This filter is specifically designed for use with a central wavelength (CWL) of 515nm, making it suitable for applications that require precise wavelength selection. The filter features a hard coating on both the front and back surfaces, ensuring durability and resistance to wear and tear.
The filter's geometry includes a diameter of 25mm and a thickness of 3.5mm, providing a robust and compact design. The cut-on wavelength is 512.5nm, and the cut-off wavelength is 517.5nm, indicating a narrow bandwidth that aids in the rejection of unwanted wavelengths.
The 39-349 filter is coated with EDM 39-331 on both the front and back surfaces, enhancing its performance and longevity. Its thin lens shape allows for easy integration into various optical systems. The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
