84-794 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 450nm

The 84-794 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 50 mm and a thickness of 3.5 mm. The filter's primary function is to transmit light within a specific range of wavelengths while blocking other wavelengths.

This Bandpass Filter has a center wavelength (CWL) of 450 nm, making it ideal for applications that require the transmission of blue light. The filter's passband, defined by its cut-on wavelength of 425 nm and cut-off wavelength of 475 nm, is a 50 nm band. This narrow passband is crucial in applications where stray light or out-of-band signals need to be minimized.

The filter is made from UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The front and back surfaces of the filter are coated with EDM 84-770, a hard coating that enhances the filter's durability and resistance to environmental factors.

The 84-794 filter is designed to be used as a Thin Lens, which means it can focus or diverge light rays, making it suitable for use in imaging systems. The filter is currently in stock and available for immediate purchase, as indicated by its weblink status.
