67-298 25 mm Dia. Traditional Coated OD 2.0 Longpass Filter; t=3mm 1175nm
The 67-298 is a Longpass Filter, part of the extensive catalog of optical elements offered by Edmund Optics. This filter, with a diameter of 25 mm and a thickness of 3 mm, is designed for use in a variety of optical applications.
The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It is designed to cut on at 1175 nm, allowing light of longer wavelengths to pass through while blocking shorter wavelengths. The cut off is 0 nm, indicating that it allows all longer wavelengths to pass through.
The 67-298 features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. This makes it ideal for use in precision optical systems.
The filter is coated on both the front and back with EDM 67-295, a coating that enhances its optical performance and durability. This coating helps to protect the filter from scratches, dust, and other environmental factors that could degrade its performance over time.
The 67-298 is currently in stock and available for purchase through the Edmund Optics website. With its high-quality construction, advanced coating, and precision design, this filter is an excellent choice for a wide range of optical applications.
