A four-chip camera uses four image sensors. The allocation of visible and near-infrared channels depends on the design; chip count alone does not establish image quality or fluorescence sensitivity. UnivLabs lists a four-chip CMOS camera in its Spectra suite. Ask for the proposed camera’s confirmed channel architecture and output specification.
01
Capture the right wavelengths
Optical filters and sensors determine which wavelengths a camera detects. Multi-channel designs can separate spectral information, but the exact channel allocation must come from the camera’s technical documentation.
02
Keep colour and fluorescence aligned
If a system combines views from separate channels, registration and synchronisation matter. Ask to see the overlay at different working distances rather than inferring performance from the number of sensors.
03
Inspect the complete output
Check the native resolution, frame rate and latency for each mode, including recorded output. A single-sensor camera can also deliver 4K; sensor count and output resolution answer different questions.
