The 590nm IR Drop-In Filter from Kolari Vision is compatible with the EF to EOS R drop-in filter adapter from Kolari or Canon. It blocks visible light up to 590nm from the light spectrum. It features an aluminum frame and multicoated glass optics. The filter has a wide grip and offers a lanyard attachment point for your convenience. It's thickness-matched to minimize focus shift.

This 590nm version requires a full spectrum modification to be made to your camera in order to function properly. This entails manually removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, the filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)
