Protective Window for ASI Cameras

Description

A replacement protective window (also called a sensor cover glass or dust window) for ZWO ASI cameras. The protective window sits in front of the camera sensor, shielding it from dust, moisture, and accidental contact during filter changes and optical train assembly.

If your original window has become scratched, damaged, or contaminated beyond cleaning, this replacement restores optical clarity. Available in various sizes to match different ZWO ASI camera models — check compatibility with your specific camera before ordering. The window is AR-coated to minimize reflections and maintain image quality.
