Visual Color Bandpass Series
XNiteBP450, XNiteBP525 and XNiteBP625 are visible bandpass filters with the center frequencies located at the center of the same frequencies as a digital camera's RGB sensor. However, unlike the camera's RGB response, these filter do not leak into each other in the viisble spectrum.
The XNiteBP450, XNiteBP525 and XNiteBP625 do open in the infrared spectrum above 825nm. Because of this, if you will be using a camera that sees both visible and infrared light simultaneously, you also use a CC1 filter to block the infrared. If you are using a stock camera, the infrared frequencies will be blocked by the camera's internal IR Cut Filter.a

CCD and CMOS image sensors only see black and white. In order for the camera to see color, small color filters are printed on top of the image sensors. These filters are typically arranged in a Bayer pattern.
Below is the typical response curve for CCD and CMOS image sensors. The top dark blue channel shows the quantum efficiency of an unfiltered image sensor. The Red, Green and Blue traces show the transmission response after the light passes through the mosaic color filter over the image sensors.
When we convert a camera to see IR+Visible or IR-Only, the majority of the infrared data will come in on the red channel. Interestingly, the blue and green channels will see some infrared but will be much lower than the red channel.
