12-280 25 mm Dia. High Performance Laser Line Bandpass Filter; t=2mm 852nm

The 12-280 is a high-performance laser line bandpass filter, designed and manufactured by Edmund Optics. This filter, with a diameter of 25 mm, is specifically engineered for use with 852 nm lasers, making it an ideal choice for applications that require precise wavelength selection.

The filter is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material ensures high-fidelity light transmission, reducing the risk of signal distortion or loss. The filter's thickness is 2 mm, providing sufficient structural integrity while maintaining minimal optical path difference.

The 12-280 features a thin lens shape, optimized for ease of integration into various optical systems. The front and back surfaces of the filter are coated with EDM 12-272, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.

The filter's physical data includes a center wavelength (CWL) of 852 nm, ensuring accurate wavelength selection. The filter is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by its weblink status.
