Application context

Why this design is used

Choose the ATR533M when your telescope and target benefit from 1-inch square, 11.31 × 11.31 mm sensor coverage, 3.76 µm sampling, two-stage TEC, ΔT ≥45 °C and 380–1100 nm response.

Deep-sky astrophotography

Two-stage TEC, ΔT ≥45 °C helps control thermal noise during long exposures of galaxies, nebulae and star clusters.

Narrowband nebula imaging

The monochrome IMX533 sensor is suited to H-alpha, O III and S II filter workflows.

High-resolution galaxy and lunar imaging

3.76 µm pixels balance image scale and detail for appropriately matched telescope focal lengths.

Photometry and time-series imaging

14-bit acquisition, 92 dB dynamic range and regulated cooling support repeatable quantitative observations.

Integration and compatibility

Use these checks to connect ATR533M 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 IMX533 monochrome CMOS · Sensor Type: Back-illuminated square 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: 40 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: 92 dB · Read Noise: 1.84–0.27 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.

Technical FAQ

Integration questions for ATR533M

What lens mount is required for the ATR533M?

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.

What sensor and pixel pitch does the ATR533M use?

Sensor: Sony IMX533 monochrome CMOS · Sensor Type: Back-illuminated square 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.

How does the ATR533M connect to the acquisition computer?
