The 65-169 is a Bandpass Filter with a diameter of 25 mm, manufactured by Edmund Optics. This filter is specifically designed for use with a central wavelength of 647 nm, making it ideal for applications that require precise wavelength selection.
The filter is hard coated on both the front and back surfaces with the EDM 65-108 coating, providing excellent durability and resistance to environmental factors. The coating also enhances the filter's performance by reducing unwanted reflections and increasing transmission.
The physical data of the filter includes a cut-on wavelength of 642 nm and a cut-off wavelength of 652 nm. This 10 nm bandpass ensures a high level of wavelength specificity, allowing for effective filtering of unwanted light.
The filter has a thickness of 3.5 mm and is shaped as a thin lens. This design not only provides excellent optical performance but also ensures ease of integration into various optical systems.
The 65-169 is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website using the provided weblink.
