67-841 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 740nm
The 67-841 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 5.9 mm, designed for optimal performance at a central wavelength of 740 nm. This filter is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
This bandpass filter is specifically designed to transmit light within a narrow range of wavelengths, while effectively blocking light outside this range. The physical data of this filter reveals a cut-on wavelength of 735 nm and a cut-off wavelength of 745 nm, with a center wavelength (CWL) of 740 nm, ensuring a full width at half maximum (FWHM) of 10 nm.
The 67-841 filter boasts a circular base shape and is composed of the material identified as "uvfs mal- 1965". The front and back of the filter are coated with the same coating, EDM 67-774, which is a traditional coating that enhances the filter's performance and durability.
The filter's geometry is defined by its 25 mm diameter and 5.9 mm thickness, and it features a thin lens shape. This combination of features makes the 67-841 an ideal choice for a wide range of optical applications that require precise wavelength selection and high transmission efficiency.
