86-970 50 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 875nm
The 86-970 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow wavelength transmission range. Sourced from Edmund Optics, this filter features a circular shape with a 50 mm diameter 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.
The 86-970 is designed to transmit light at a central wavelength (CWL) of 875nm, with a full width at half maximum (FWHM) of 50nm. This means it allows light between 850nm and 900nm to pass through, making it ideal for applications that require a tight wavelength control. The filter is hard coated on both sides with EDM 86-946, a coating that enhances its durability and performance.
This filter is categorized as a Thin Lens, indicating its ability to bend light and focus it to a specific point. This property can be beneficial in certain optical system designs. The 86-970 is currently in stock and available for immediate purchase through the provided weblink.
