87-200 25 mm Dia. Infrared (IR) Neutral Density Filter; OD 1.5 2-14µm
The 87-200 is a Neutral Density Filter with a 25 mm diameter, designed for use in the infrared (IR) spectrum with a wavelength of 588 nm. This filter is sourced from Edmund Optics, a reputable vendor known for their high-quality optical elements. The filter is made of Germanium Burnett, a material specifically chosen for its properties in the IR spectrum.
The filter is coated with EDM 12-014 on both the front and back surfaces, which is a unique coating developed by Edmund Optics. This coating enhances the filter's performance in the IR spectrum, providing a high level of neutral density. The filter's geometry includes a thickness of 1 mm, making it suitable for use in a variety of optical systems.
The 87-200 is shaped as a Thin Lens, which is a type of lens with a very small focal length compared to its diameter. This shape allows the filter to be used in compact optical systems where space is limited. The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
