The 87-889 is a Bandpass Filter, specifically designed for applications requiring a narrow passband. This filter, with a diameter of 12.5 mm, is sourced from Edmund Optics, a reputable vendor in the optical industry. The filter features a hard coating on both the front and back surfaces, ensuring durability and resistance to wear and tear.
The filter's physical data includes a cut-on wavelength of 745nm and a cut-off wavelength of 755nm, with a central wavelength (CWL) of 750nm. This specificity in wavelength makes the filter ideal for applications that require precise light filtering. The filter's geometry includes a thickness of 3.5 mm, providing structural stability and minimizing optical distortions.
The 87-889 filter is made of UVFS Mal-1965 material, a common choice for optical filters due to its excellent optical properties. The filter's shape is thin lens, which is beneficial for applications where space is a constraint.
