65-737 12.5 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 650nm
The 65-737 is a mounted traditional coated bandpass interference filter, available from Edmund Optics. This filter has a 12.5 mm diameter and a thickness of 7.5 mm, making it suitable for a wide range of optical applications.
The filter is designed to transmit light in the center wavelength (CWL) of 650 nm, with a full width at half maximum (FWHM) of 80 nm. This means it allows a narrow band of light around the 650 nm wavelength to pass through while blocking other wavelengths. This property makes it ideal for applications that require the selection of specific wavelengths, such as fluorescence microscopy or laser spectroscopy.
The filter's cut-on wavelength is 610 nm, and the cut-off wavelength is 690 nm. This means that it begins to transmit light at 610 nm and stops transmitting at 690 nm. The cut-on and cut-off wavelengths are crucial in determining the filter's blocking capabilities.
The 65-737 filter features a thin lens shape and is coated on both the front and back surfaces with the EDM 65-737 coating. This coating enhances the filter's performance by reducing surface reflections and improving transmission.
The filter is currently in stock and can be purchased directly from the Edmund Optics website. It is cataloged under number 65-737, making it easy to find and order.
