The Imaging Source DFK 33UX290.AS, 1/2.8 " CMOS STARVIS, Sony IMX290LQ (progressive scan).

The Imaging Source DFK 33UX290.AS

Color USB 3.0 astronomy camera with IR cut filter.

  • 1/2.8 " CMOS STARVIS, Sony IMX290LQ (progressive scan).
  • Resolution 1920 x 1080 pixels (2.1 MP).
  • Up to 143 FPS and 30 seconds exposure.
  • C mount.
  • Software included.

The camera ships with IC Capture.AS, a comprehensive software package with which you can capture lossless and uncompressed images sequences and write them to disk as AVI files, or as a series of singular bitmaps.

Color Interpolation

For visualization applications, it does not make sense to view the RAW image stream from the CMOS STARVIS chip. It must be interpolated, before it may be viewed or saved in common formats. IC Capture.AS perform color interpolation, thus reducing the load on the DFK 33UX290.AS's processor. Should, on the other hand, you prefer that the camera itself performs color interpolation, you can select the appropriate option in IC Capture.AS. This enables the transfer of data to reach the camera's maximum of 143 FPS. Finally, if you do not require color interpolation at all, you can turn it off completely and the image stream is written to disk in RAW format.

Sony IMX290LQ 1/2.8 " CMOS STARVIS Chip

The DFK 33UX290.AS ships with the color Sony IMX290LQ progressive scan CMOS STARVIS chip. With its 1/2.8 " format, the CMOS STARVIS chip produces a resolution of 1920 x 1080 pixels. Thanks to this extremely high quality, the Sony IMX290LQ CMOS STARVIS chip is also often used in other scientific, industrial and medical image processing applications.

IR Cut Filter As Standard

Unlike the human eye, CMOS STARVIS chips are sensitive to near infrared light (wavelengths over 700 nm). The DFK 33UX290.AS ships with an IR cut filter as standard and is thus suited to applications in which these wavelengths would lead to interference or undesirable results.

High Speed Data Transfer Via USB 3.0

In order to transfer the vast amount of data created by the stream of uncompressed and lossless color images to the host PC, you need a very high speed bus. Hence, the DFK 33UX290.AS is fitted with a fast USB 3.0 connector.

Included Software

The DFK 33UX290.AS ships with the device driver and the camera control and image acquisition application IC Capture.AS. Both of these run on Windows 10, Windows 7, Windows Vista and Windows XP (32 and 64 bit).

Software for Mac OS and Linux is available from third parties.
