The Astronomik IR Blocker is an essential infrared-blocking filter designed for digital photography. It is ideal for imaging applications with sensors that have low UV sensitivity, such as Webcams, Meade DSI and LPI, or most video systems. By placing this filter in front of your camera, you can eliminate issues caused by infrared light, such as bright halos around objects and an overall soft image. With its superior transmission data, the Astronomik IR Blocker outperforms standard UV-IR blockers offered by other manufacturers.

Optimized for systems with focal ratios between f/0.5 and f/50, this filter achieves a typical transmission rate of over 99%. It blocks all IR light without altering the visual spectrum, making it a perfect parfocal filter. Additionally, it serves as excellent dust protection for your telescope and camera.
