Within each module, the light is split by a dichroic and sent to a short-wavelength (SW, 0.6-2.3 μm) and a long-wavelength (LW, 2.4-5 μm) channel. Each SW module is split into 4 separate detectors. In total, NIRCam images simultaneously with ten 2040x2040 detectors, for a total of more than 41 million pixels. The short-wavelength channel has a pixel scale of ~0.031", which Nyquist-samples a point source at 2 μm. The long-wavelength channel has a pixel scale of ~0.063". Each channel has a comprehensive selection of wide-, medium-, and narrow-band filters.
