65-167 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 636nm

The 65-167 is a Bandpass Filter with a diameter of 25 mm, sourced from the reputable optical components vendor, Edmund Optics. This filter is specifically designed for use with a central wavelength of 636 nm, making it suitable for a wide range of applications that require precise wavelength selection.

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 stability and minimizing the risk of deformation or damage during handling or installation.

The 65-167 features a Cut-On wavelength of 631 nm and a Cut-Off wavelength of 641 nm. This 10 nm bandpass ensures high transmission efficiency within the specified wavelength range, while effectively blocking out unwanted spectral components.

The filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 65-106, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and durability, providing excellent environmental resistance and ease of cleaning.

The filter's shape is defined as a Thin Lens, which is a common and versatile form factor in optical systems. This shape allows for easy integration into existing systems or designs, making the 65-167 a highly adaptable and practical choice for many applications.
