67-848 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 800nm
The 67-848 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its circular shape, with a diameter of 25 mm and a thickness of 5.9 mm, making it suitable for a wide range of optical applications.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking light outside this range. In this case, the central wavelength (CWL) is 800 nm, and the full width at half maximum (FWHM) is 40 nm. This means the filter is designed to pass light between 780 nm and 820 nm, providing a narrow band of passable wavelengths.
The 67-848 filter features a coating on both the front and back surfaces, identified as EDM 67-781. This coating is designed to enhance the filter's performance and durability, ensuring optimal functionality in various conditions.
The filter's geometry is defined as a thin lens, suggesting its potential use in lens systems. The catalog number for this item is 67-848, and it can be found on the Edmund Optics website, where it is currently in stock.
