15-462 25.4 mm Dia. Dielectric Coated Colored Glass Replacement Longpass Filter 850nm

The 15-462 is a 25.4 mm diameter dielectric coated colored glass replacement longpass filter with a cut-on wavelength of 850nm, available from Edmund Optics. This filter is designed for use in optical systems where longpass filtering is required, and it features a specialized coating on both the front and back surfaces to enhance its performance.

The filter's longpass characteristic means that it allows light of wavelengths longer than 850nm to pass through while blocking or attenuating shorter wavelengths. This can be useful in a variety of applications, such as infrared (IR) imaging, spectroscopy, and other optical systems where longpass filtering is needed.

The filter is made from UVFS Mal-1965, a type of colored glass, and has a thickness of 1.1mm. It has a thin lens shape, which can be beneficial in systems where space is limited or where a thin, lightweight optical element is preferred.

The 15-462 filter is available directly from Edmund Optics, and as of the time of this writing, it is in stock and ready for immediate shipping. The filter's catalog number is 15-462, and it can be found on the Edmund Optics website at the following link: https://www.edmundoptics.com/p/850nm-254mm-dia-colored-glass-replacement-longpass-filter/43197/
