84-747 25 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=3 mm 675nm
The 84-747 is a high-performance longpass filter, measuring 25 mm in diameter and 3 mm in thickness, sourced from Edmund Optics. This filter is designed to transmit light at wavelengths above 675 nm, making it ideal for applications that require the removal of shorter wavelengths.
The filter features a circular shape and is constructed from UVFS Mal-1965 material, ensuring durability and high-quality performance. It boasts a cut-on wavelength of 675 nm, meaning it begins to transmit light at this point, and has a cut-off wavelength of 0 nm, indicating it blocks all wavelengths below this point.
The 84-747 is coated with EDM 84-741 on both the front and back surfaces, enhancing its performance and longevity. This coating helps to reduce unwanted reflections and increase the filter's efficiency. The filter's shape is classified as a Thin Lens, further contributing to its high-performance capabilities.
