65-673 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 337nm
The 65-673 is a mounted traditional coated bandpass interference filter, designed and manufactured by Edmund Optics. This filter is characterized by its 25 mm diameter and 7.5 mm thickness, making it a robust and stable option for various optical applications.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking out unwanted wavelengths. In this case, the central wavelength (CWL) is 337nm, with a full width at half maximum (FWHM) of 10nm. This makes it particularly suitable for applications that require the precise filtering of ultraviolet light.
The cut-on wavelength is 332nm, and the cut-off wavelength is 342nm. This means that the filter begins to transmit light at 332nm and stops transmitting at 342nm, effectively filtering out any wavelengths outside this range.
The filter is coated with EDM 65-613 on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation.
The filter's shape is that of a thin lens, which contributes to its compact design and ease of integration into various optical systems. The catalog number for this filter is 65-673, and it is currently in stock, according to the vendor's website.
