Technical FAQ
Lens Mount: M72×0.75 (native). Use a lens image circle that covers the sensor and check flange distance before adding C/CS, F-mount or M42 adapters.
Sensor: IMX811ALR (M, RS) · Resolution: 251 MP (19200×12800). 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: 1.5 fps @ 19200×12800 · Interface: USB3.0. 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× direct-connect GPIO. 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: Available on request. 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.
Tell us your sensor, resolution, spectral range, frame-rate, interface, and software requirements and we will confirm the matching configuration and lead time.
