The 49mm Kolari Vision UV/IR Cut Hot Mirror Filter 49mmfrom Kolari Vision UV/IR Cut Hot Mirror Filter 49mmis designed to normalize your camera when it has either a full spectrum or two-spectrum modification. In either case, it allows light to pass normally to the sensor, so you can shoot normal photos. The filter is designed with coated glass optics and an aluminum filter ring threaded on both sides. (The optional pro version has a knurled brass ring.)

The filter can only be used with a modified camera. A spectrum-modified camera is one in which the camera's native low-pass filter was removed in order to support certain IR filters for IR photography. If you have such a camera, this hot mirror filter will let you take normal photos without having to make any changes to the spectrum modification. The filter blocks IR light and some UV light, the same way the native low-pass filter that was removed from the camera during modification would have. The filter requires no exposure compensation.
