86-743 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 785nm

The 86-743 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. 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 allow light within a specific wavelength range to pass through while blocking other wavelengths, making it ideal for applications requiring precise wavelength control.

The 86-743 filter is designed to transmit light at a central wavelength (CWL) of 785 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows light between 780 nm and 790 nm to pass through, making it highly selective. The filter's cut-on wavelength is 780 nm, and the cut-off wavelength is 790 nm, further illustrating its narrow bandpass characteristics.

This filter is hard coated on both the front and back surfaces with EDM 86-735, a proprietary coating developed by Edmund Optics. This coating enhances the filter's durability and resistance to environmental factors, ensuring long-term performance and reliability. The filter's shape is defined as a Thin Lens, indicating a precise curvature designed to control the path of light within an optical system.
