65-749 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 950nm
The 65-749 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 950nm, with a full width at half maximum (FWHM) of 50nm, making it ideal for applications that require narrowband transmission. The filter features a thin lens shape, ensuring minimal optical aberrations and distortions.
The filter's physical dimensions include a diameter of 25mm and a thickness of 7.5mm, providing a robust and compact design suitable for various optical systems. The cut-on wavelength is 925nm, and the cut-off wavelength is 975nm, further enhancing its narrowband transmission properties.
The 65-749 filter is coated with EDM 65-740 on both the front and back surfaces. This coating provides excellent optical performance, including high transmission and low reflectance, ensuring optimal light propagation through the filter.
The filter is available for purchase through the Edmund Optics website, and as of the time of data collection, it is in stock. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
