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: GSENSE6504BSI (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: 298 fps @ 2048×2048 (CoaXPress 2.0 ×4 or USB3.2 Gen 2x2, 8-bit/12-bit); 170 fps @ 16-bit · Interface: USB3.2 Gen 2x2 / CoaXPress 2.0 ×4. 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.
External Trigger: Supported via digital I/O · 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.
Full Well Capacity: 1.03 ke⁻ (high sensitivity mode); 13.48 ke⁻ (HDR mode) · Dynamic Range: 62.1 dB (high sensitivity mode); 86 dB (HDR mode). 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.
