ZWO 850nm IR Band-pass Filter (31.7mm, 1.25") for IR Sensitive Cameras
The ZWO 1.25″ IR 850nm Pass Filter is suitable for IR sensitive cameras. You don’t need to debayer and get the full resolution of this sensor when use it with a color camera such as the ZWO ASI224MC or ASI185MC, because the QE responce of sensor beyond 850nm is all the same (i.e. infrared light passes through the Bayer colour layer). So you can use a color camera as mono camera with this filter, just don’t forget to keep the WB_R and WB_B settings to 50 (no White Balance applied).
ONLY FOR PHOTOGRAPHIC USE! This filter is not suitable for visual observations as humans won't see anything in that part of the spectrum.
