43-949 50.8 mm Dia. Black Optical Cast Infrared (IR) Longpass Color Filter

The 43-949 is a 50.8 mm diameter optical cast plastic IR longpass filter, manufactured by Edmund Optics. This filter is designed to transmit infrared light with wavelengths longer than 588 nm while blocking shorter wavelengths. It features a circular shape and a thin lens design, making it suitable for a wide range of optical applications.

The filter is made from UVFS MAL-1965 material, a high-quality optical plastic known for its excellent transmission properties in the infrared region. It has a diameter of 50.8 mm and a thickness of 1.5 mm, providing a balance between compactness and durability.

The 43-949 filter is coated with EDM IR-VIS on both the front and back surfaces. This coating enhances its infrared transmission capabilities and also provides protection against visible light, reducing the risk of unwanted reflections or scattering.

This filter is currently in stock and available for purchase through the Edmund Optics website. Its catalog number is 43-949, and it can be found at the following link: https://www.edmundoptics.com/p/2quot-diameter-optical-cast-plastic-ir-longpass-filter/5418/.
