The 67-903 is a Bandpass Filter with a 50 mm mounted diameter, designed for use in optical systems that require a narrow bandwidth of light centered at 660 nm. This filter is sourced from Edmund Optics, a leading vendor in the field of optical components.
The filter features a cut-on wavelength of 655 nm and a cut-off wavelength of 665 nm, providing a full width at half maximum (FWHM) of 10 nm. This makes it ideal for applications that demand high spectral selectivity and transmission, such as fluorescence microscopy, spectroscopy, and laser systems.
The 67-903 filter is constructed with a base shape of Circular geometry and a thickness of 5.9 mm. It is made from UVFS Mal-1965 material, ensuring durability and stability under various operating conditions. The filter is coated on both the front and back surfaces with EDM 67-769, a traditional coating that enhances its performance and longevity.
The filter's shape is designed as a Thin Lens, allowing for easy integration into optical systems. It is currently in stock and available for immediate purchase through the provided weblink. The catalog number for this item is 67-903.
