49-087 12.5 mm Dia. SCHOTT KG3 Heat Absorbing Glass IR Cut-Off Filter 300-2700nm

The 49-087 is a 12.5 mm diameter circular filter from Edmund Optics, designed for heat absorption and infrared (IR) cut-off applications. This filter is made of SCHOTT KG3 glass, a material known for its excellent optical properties and durability.

The filter has a base shape of a thin lens, with a thickness of 3 mm, providing a good balance between robustness and light transmission. It is designed to cut off infrared light at 300 nm and allow light transmission up to 2700 nm, making it suitable for a wide range of applications where infrared light needs to be controlled or eliminated.

The 49-087 filter features front and back coatings of EDM 49-087, which enhances its performance and durability. The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status.
