65-747 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 700nm
The 65-747 is a mounted traditional coated bandpass interference filter, available from Edmund Optics. This filter has a 25 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) range of 700 nm, with a full width at half maximum (FWHM) of 80 nm. This means it allows a narrow band of wavelengths around 700 nm to pass through while blocking other wavelengths. This feature is particularly useful in applications where specific wavelength selection is required, such as in spectroscopy or fluorescence microscopy.
The 65-747 filter is cut on at 660 nm and cut off at 740 nm. This means that it starts transmitting at 660 nm and stops transmitting at 740 nm. The cut-on and cut-off wavelengths are crucial in determining the filter's performance in a given application.
The filter is coated with EDM 65-738 on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and increasing transmission. It also provides protection to the filter surface, thereby increasing its durability.
The filter's thin lens shape allows for easy integration into optical systems. It is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
