ZWO ASI290MM USB3.0 Monochrome Astronomy CMOS Camera

ZWO ASI 290 MM USB3.0 Monochrome Astronomy CMOS Camera

The small 2.9 µm pixels and back illuminated architecture provides enhanced picture quality in low light while still realizing full HD capture.

The benefit for astronomy is more than 2x the sensitivity in visible light and more than 3x the sensitivity in near infrared over existing Sony sensors (eg: IMX236LQJ).

Product Description

Camera Sensor

▶IMX290LQR, IMX291LQR

Diagonal 6.46 mm (Type 1/2.8) Square Pixel Array Mono CMOS Image Sensor

▶Back-Illuminated CMOS image Sensors with Improved Visible Light and Near Infrared Sensitivity that Support 1080p

Sony has developed the approx. 2.13M effective pixel back-illuminated CMOS image sensors IMX290LQR and IMX291LQR with improved sensitivity in the visible-light and near infrared light regions for industrial applications.
A new 2.9 µm-square unit pixel has been developed that combines a back-illuminated structure with technology for improving near-infrared sensitivity to further enhance picture quality at low illumination while at the same time realizing Full HD cameras for industrial applications.

This increases the sensitivity by as much as a factor 2 or factor 3 in the visible-light region and more than a factor 3 of the sensitivity in the near infrared light region, than that of the existing Sony product (IMX236LQJ).

Astrophotography Performance

ASI 290MM offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak about 80%, AR protective window and much more.

High QE

Regarding the relative QE Curve, we estimate the Peak Value to be about 80%.

USB 3.0 Port & ST4 Port

USB 3.0 Port: Can provide 5Gb bandwidth to let ASI290 run at 82.2fps (12bit, normal mode) or 170 fps (10bit, high speed mode)  at full resolution(2.1Mega).

ST4 Port: Can be used to connect with the auto guide port of the mount, for guiding.
