Technical FAQ
Lens Mount: C-mount. Use a lens image circle that covers the sensor and check flange distance before adding C/CS, F-mount or M42 adapters.
Sensor: GSENSE2020BSI (sCMOS) · Resolution: 4.2 MP (2048×2048). Match pixel pitch to the diffraction-limited spot the optics deliver. Sampling finer than the optics resolve multiplies data volume without adding information; sampling coarser discards resolution you have paid for.
Frame Rate: 72.5 fps @ 2048×2048; 72.5 fps @ 1024×1024 · Interface: USB 3.0. Confirm the host can sustain the interface bandwidth continuously, not in burst. A camera that outruns the write path stalls acquisition rather than dropping quietly to a lower rate.
GPIO: 1 opto-isolated input, 1 opto-isolated output, 2 non-isolated I/O ports. Confirm edge polarity, pulse-width limits and whether each line is opto-isolated before connecting TTL or GPIO signals. A software exposure command is not equivalent to a hardware trigger.
Dynamic Range: 61.38 dB (11-bit); 59.73 dB (HCG, 12-bit) / 67.17 dB (LCG, 12-bit); HDR 91.83 dB (11HL) / 86.02 dB (12HL). Judge these figures at the exposure time you will actually use. Cooling matters where dark current accumulates over seconds; read noise dominates short exposures where it never does.
