86-669 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 650nm

The 86-669 is a Bandpass Filter, specifically designed for applications requiring a narrow passband. This filter, sourced from Edmund Optics, boasts a 50 mm diameter and a thickness of 3.5 mm, making it suitable for a wide range of optical systems.

The filter's primary function is to transmit light within a specific wavelength range, while blocking other wavelengths. In this case, the Cut-On wavelength is 637.5 nm, and the Cut-Off wavelength is 662.5 nm, with a Central Wavelength (CWL) of 650 nm. This makes it ideal for applications where a high level of precision and specificity in light transmission is required.

The 86-669 features Hard Coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also reduces surface reflections, improving the overall efficiency of the optical system.

The filter's geometry is defined by its circular shape and thin lens design, which contributes to its versatility and ease of integration into various optical systems. The material ID, UVFS MAL-1965, provides additional information about the filter's composition and properties.
