39-316 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 808nm

The 39-316 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter is a high-quality optical component designed for precise wavelength selection, sourced from the renowned vendor Edmund Optics. This filter is specifically designed for use at the 808nm wavelength, offering a narrow bandwidth of 10nm, making it ideal for applications that require high spectral purity and rejection of unwanted out-of-band light.

The filter features a circular geometry with a diameter of 25mm and a thickness of 3.5mm, providing a robust and compact design suitable for various optical systems. The hard coating on both the front and back surfaces enhances the filter's durability, ensuring long-term performance and resistance to environmental factors such as scratching and dust accumulation.

The 39-316 filter's physical data includes a cut-on wavelength of 803nm and a cut-off wavelength of 813nm, with a central wavelength (CWL) of 808nm. This ensures a tight passband around the desired wavelength, effectively suppressing unwanted light and reducing noise in the system. The coating on both surfaces is identical, utilizing the EDM 39-309 coating, which further contributes to the filter's overall performance and reliability.
