The Imaging Source DMK 33GX265e.AS, 1/1.8 " CMOS Pregius, Sony IMX265LL (progressive scan).

The Imaging Source DMK 33GX265e.AS

Monochrome GigE astronomy camera without IR cut filter.

  • 1/1.8 " CMOS Pregius, Sony IMX265LL (progressive scan).
  • Resolution 2048 x 1536 pixels (3.1 MP).
  • Up to 36 FPS and 4 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.

Sony IMX265LL 1/1.8 " CMOS Pregius Chip

The DMK 33GX265e.AS ships with the monochrome Sony IMX265LL progressive scan CMOS Pregius chip. With its 1/1.8 " format, the CMOS Pregius chip produces a resolution of 2048 x 1536 pixels. Thanks to this extremely high quality, the Sony IMX265LL CMOS Pregius chip is also often used in other scientific, industrial and medical image processing applications.

No Compression, No IR Cut Filter

The DMK 33GX265e.AS does not compress the video stream it outputs - the video data that is captured by the CMOS Pregius chip is outputted directly by the GigE connector. Similarly, the camera does not have an IR cut filter, a color filter, nor an other kind of electronic filter. The camera is, therefore, ideally suited to capturing very true-to-life images of the night sky.

High Speed Data Transfer Via GigE

In order to transfer the vast amount of data created by the stream of uncompressed and lossless monochrome images to the host PC, you need a very high speed bus. Hence, the DMK 33GX265e.AS is fitted with a fast GigE connector.

Included Software

The DMK 33GX265e.AS ships with the device driver IC WDM GIGE TIS 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.
