84-803 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 900nm

The 84-803 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, making it suitable for a wide range of applications.

The filter is designed to transmit light within a specific wavelength range, in this case, 900 nm, while blocking light at other wavelengths. The cut-on wavelength is 875 nm, and the cut-off wavelength is 925 nm, providing a 50 nm passband. This precise wavelength selection is crucial in many applications, such as fluorescence microscopy, spectroscopy, and laser systems.

The 84-803 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 84-779, a hard coating that enhances the filter's durability and resistance to environmental factors, ensuring long-term performance.

The filter's thin lens shape allows for easy integration into optical systems, while its hard coating ensures minimal scattering and loss of light, contributing to overall system efficiency. The filter's weblink status indicates that it is currently in stock, making it readily available for immediate use.
