12-243 25 mm Dia. Infrared (IR) Neutral Density Filter; OD 0.3 2-14µm

This is a 12-243 25 mm Dia. Infrared (IR) Neutral Density Filter, designed for use in optical systems that require attenuation of infrared light while maintaining color neutrality. The filter has a diameter of 25 mm and a thickness of 1 mm, making it suitable for a wide range of applications.

The filter is made from Germanium Burnett, a material known for its excellent optical properties in the infrared region. It features a neutral density of 0.3, which corresponds to a transmission of approximately 37%. This makes it ideal for applications where a reduction in light intensity is required without altering the color balance.

The filter is coated on both sides with EDM 12-003, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The coating also provides protection against environmental factors, ensuring the filter maintains its performance over time.

The filter's shape is described as a Thin Lens, which refers to its optical design. This shape is often used in optical systems where a thin, lightweight element is required. The filter is in stock and available for purchase on the Edmund Optics website, as indicated by its weblink status.
