67-857 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 900nm

The 67-857 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its circular shape, with a diameter of 25 mm and a thickness of 5.9 mm, making it suitable for a wide range of optical applications.

The filter's primary function is to allow light in a specific wavelength range to pass through while blocking other wavelengths. In this case, the cut-on wavelength is 895 nm, and the cut-off wavelength is 905 nm, with a central wavelength (CWL) of 900 nm. This makes it ideal for applications that require narrow-band filtering around the 900 nm range.

The 67-857 filter features a UVFS MAL-1965 material ID, ensuring high-quality performance and durability. The front and back of the filter are coated with EDM 67-790, providing additional protection and enhancing its optical properties.

The filter's geometry and physical data suggest that it is a thin lens, which can be beneficial in applications where space is a constraint. The filter's weblink status indicates that it is currently in stock, making it readily available for immediate use.
