Monochrome sensor which is sensitive to IR portion of the spectrum. With film it s easy, just pop the IR sensitive film and that was all. With digital, it is different, as the sensor has a colour filter on each pixel in Bayer pattern. So for all practical purpose only the RED pixels will contribute to the image, degrading the resolution. Monochrome sensors have no such pattern. They also have no IR filter, which is used to block IR, as it will not only heat up the sensor inadvertently.2. Lenses which are APOCHROMATIC, that is those that focus at the same point across the spectrum.</blockquote>
