ATR585M

Application context

Why this design is used

Choose the ATR585M when your telescope and target benefit from 1/1.2-inch, 11.2 × 6.3 mm sensor coverage, 2.9 µm sampling, two-stage TEC, ΔT ≥45 °C and 380–1100 nm response.

System integration

Integration and compatibility

Use these checks to connect ATR585M 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: M42 / M54 astronomy adapters

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 IMX585 monochrome CMOS · Sensor Type: STARVIS 2 back-illuminated monochrome 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: 47 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: 88.6 dB HDR · Read Noise: 3.04–0.50 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.
