67-906 50 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 710nm

The 67-906 is a Bandpass Filter with a circular base shape, designed and manufactured by Edmund Optics. This filter is mounted with a diameter of 50 mm and a thickness of 5.9 mm, making it suitable for various optical applications. The filter features a UVFS MAL-1965 material ID, which is known for its excellent optical properties.

The primary function of this filter is to allow light transmission within a specific range of wavelengths while blocking light outside this range. The 67-906 is designed to transmit light at a central wavelength (CWL) of 710 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows a narrow band of light around 710 nm to pass through while blocking other wavelengths.

The filter's cut-on wavelength is 705 nm, and the cut-off wavelength is 715 nm. This means that it starts transmitting light at 705 nm and stops transmitting at 715 nm. This precise wavelength selection is crucial in many optical systems, such as spectroscopy, fluorescence microscopy, and laser applications.

The 67-906 is coated with EDM 67-772 on both the front and back surfaces. This coating enhances the filter's performance by reducing reflections and increasing transmission. The filter's shape is that of a thin lens, which contributes to its compact design and ease of integration into optical systems.
