84-743 25 mm Dia. Hard Coated High Performance OD 4.0 Longpass Filter; t=3 mm 475nm
The 84-743 is a high-performance longpass filter, measuring 25 mm in diameter and 3 mm in thickness, sourced from Edmund Optics. This filter is designed for use in optical systems that require a longpass cut-on wavelength of 475 nm.
The filter is made from UVFS Mal-1965 material, a high-quality optical material known for its durability and optical performance. It features a circular shape and a thin lens design, making it suitable for a wide range of optical applications.
The 84-743 filter is hard coated on both the front and back surfaces with EDM 84-737, a high-performance coating that enhances its durability and optical performance. This coating ensures the filter maintains its optical properties even under harsh environmental conditions.
The filter's physical data includes a cut-on wavelength of 475 nm, indicating that it begins to transmit light at this wavelength. The cut-off wavelength is 0 nm, meaning it transmits all wavelengths longer than 475 nm. The central wavelength of the filter is 588 nm.
This filter is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.edmundoptics.com/p/475nm-25mm-dia-high-performance-longpass-filter/27812/.
