Integration and compatibility
Use these checks to connect G3CMOS10300KPA to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Lens and microscope interface
- Mount: Astronomy adapter / telescope interface
- Use a lens image circle that covers the sensor and check flange distance before adding C/CS, F-mount or M42 adapters.
- Sensor and sampling
- Sensor: Sony IMX294 color CMOS · Sensor Type: Back-illuminated 4/3-inch color CMOS
- 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.
- Interface and data rate
- Frame Rate: 33 fps · 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.
- Cooling and noise floor
- Dynamic Range: 84.4 dB · Read Noise: 4.1–3.38 e⁻
- 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.
