67-781 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 800nm

The 67-781 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter is a high-quality optical component designed for precise wavelength selection. Sourced from the renowned vendor Edmund Optics, this filter is a Bandpass type, specifically designed to allow light transmission in a narrow band of wavelengths while blocking light outside this range.

The filter features a circular geometry with a diameter of 12.5 mm, ensuring a wide range of applications. It has a thickness of 5.9 mm, providing robustness and stability. The filter is made from UVFS MAL-1965 material, a common choice for optical filters due to its excellent optical properties.

The 67-781 filter is designed to operate at a central wavelength of 800 nm, making it suitable for applications that require precise filtering in the near-infrared region of the spectrum. It has a Full Width at Half Maximum (FWHM) of 40 nm, indicating a relatively narrow bandwidth, which is ideal for applications that require high wavelength selectivity.

The filter's cut-on wavelength is 780 nm, and the cut-off wavelength is 820 nm. This means that the filter starts transmitting light at 780 nm and stops transmitting at 820 nm, effectively blocking any light outside this range.

The filter is coated on both the front and back surfaces with EDM 67-781 coating. This coating enhances the filter's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.

The filter's shape is a Thin Lens, which is a common shape for optical filters. This shape ensures easy integration into various optical systems.
