The 84-675 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter is a specialized optical component designed for applications requiring long-pass filtering at a cut-on wavelength of 1350nm. This filter, sourced from Edmund Optics, is a circular element with a 25mm diameter and a thickness of 3mm, making it suitable for a wide range of optical systems.
The filter is constructed from UVFS Mal-1965 material, a common choice for optical components due to its excellent optical properties. It features a thin lens shape, which helps minimize optical aberrations and ensures high-quality performance. The filter's longpass characteristic allows it to transmit wavelengths above 1350nm while blocking or attenuating shorter wavelengths.
The 84-675 filter is coated on both the front and back surfaces with EDM 84-667, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. The coating also provides excellent environmental stability, ensuring the filter maintains its performance characteristics over time.
