39-379 50 mm Dia. Hard Coated OD 4.0 5nm Bandpass Filter; t=3.5 mm 633nm
The 39-379 is a Bandpass Filter, specifically designed for use in optical systems that require a narrow bandwidth of light centered around 633nm. This filter is sourced from Edmund Optics, a renowned vendor in the optical industry, and features a circular shape with a diameter of 50mm and a thickness of 3.5mm.
The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent transmission properties and durability. The front and back surfaces of the filter are coated with EDM 39-333, a hard coating that enhances the filter's resistance to wear and tear, ensuring a longer lifespan and maintaining its performance over time.
The 39-379 filter is designed to pass light within a specific range of wavelengths, with a Cut-On wavelength of 630.5nm and a Cut-Off wavelength of 635.5nm. This narrow bandwidth is crucial in applications where controlling the spectral content of light is essential, such as in fluorescence microscopy, spectroscopy, or laser systems.
The filter's physical data, including its Cut-On, Cut-Off, and Central Wavelength (CWL) of 633nm, are precisely controlled during the manufacturing process to ensure high-quality performance. This filter is currently in stock and available for immediate purchase, as indicated by its weblink status.
