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: China-made 640×512 (InGaAs CMOS) · Resolution: 0.33 MP (640×512). 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: 8 Bit: 724 fps @ 640×512; Packet12: 724 fps @ 640×512; 14 Bit: 579 fps @ 640×512 · Interface: USB3. 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 optically isolated input, 1 optically 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: 70.59 dB (LG), 67.96 dB (MG), 47.98 dB (HG) *1. 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.
