87-196 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 950nm

The 87-196 is a Bandpass Filter, a type of optical filter that allows only a specific range of wavelengths to pass through while blocking others. This particular model, sourced from Edmund Optics, has a diameter of 50 mm and a thickness of 7.5 mm, making it suitable for various optical applications.

The filter is designed to operate at a central wavelength (CWL) of 950 nm, with a full width at half maximum (FWHM) of 50 nm. This means it allows a narrow band of wavelengths around 950 nm to pass through while blocking out light of other wavelengths. The cut-on wavelength is 925 nm, and the cut-off wavelength is 975 nm, further emphasizing its bandpass characteristics.

The 87-196 features a traditional coating on both the front and back surfaces, specifically the EDM 65-740 coating. This coating enhances the filter's performance by reducing reflections and increasing transmission. The filter's shape is that of a thin lens, which contributes to its versatility in optical systems.
