12-277 25 mm Dia. High Performance Laser Line Bandpass Filter; t=2mm 457.9nm

The 12-277 is a high-performance laser line bandpass filter, boasting a 25 mm diameter and a thickness of 2mm. This filter is designed to operate at a central wavelength of 457.9nm, making it ideal 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 optical performance and minimal signal interference.

The 12-277 features a thin lens shape, which is advantageous in applications where space is at a premium. The front and back surfaces of the filter are coated with EDM 12-269, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving signal quality.
