Product Description
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
ASI290MM 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 connect with auto guide port of mount, for guiding.
