Product Details
ZWO's 2" UV/IR-cut filter is suitable for color cameras with AR protection windows. The ZWO IR-Cut Filter blocks infrared and ultraviolet light from reaching the sensor of your CCD or CMOS camera or your expensive H-alpha filter. When imaging, the addition of this simple and inexpensive accessory will result in sharper images, and when doing solar work, the IR Cut Filter will your protect H-alpha filter from the damaging effects of infrared radiation.
Infrared or IR light is invisible to the human eye, and so even though most telescopes are not designed to focus IR light, it does not matter when you are using your telescope visually. However, when you add a camera to the mix, its a whole other story! Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem because infrared images are blurry as all get out. That means your nice, sharp visual light image is degraded by the addition of the infrared layer. This problem can easily be solved by blocking the infrared, and the ZWO UV/IR-Cut filter will do just that.
The ZWO UV/IR-Cut filter is housed in a 2" cell and comes with a protective plastic case. Please note that the ZWO UV/IR-Cut filter does not have usable female threads and hence cannot be stacked with other filters.
