65-164 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 610nm

The 65-164 is a Bandpass Filter with a diameter of 25 mm, sourced from the renowned optical components vendor, Edmund Optics. This filter is specifically designed for use at a central wavelength of 610nm, making it ideal for applications that require narrowband transmission in this spectral region.

The filter is constructed with a hard-coated Outside Diameter (OD) of 4.0, ensuring durability and resistance to wear and tear. It has a thickness of 3.5 mm, providing structural stability and minimizing the risk of deformation or damage during handling and installation.

The 65-164 features a Cut-On wavelength of 605nm and a Cut-Off wavelength of 615nm, resulting in a 10nm bandpass. This precise wavelength range ensures high transmission efficiency while effectively suppressing out-of-band light, making it suitable for applications that demand high spectral purity.

The filter is coated with EDM 65-103 on both the front and back surfaces. This coating enhances the filter's performance by reducing reflection and improving transmission, thereby increasing the overall system efficiency.

The 65-164 is available in a Thin Lens shape, offering versatility in optical system design. Its comprehensive specifications and high-performance characteristics make it a valuable addition to any optical setup that requires narrowband filtering at the 610nm wavelength.
