Resolution of 1280 x 960 pixels

The astronomy camera DFK 41AU02.AS exceeds with its high resolution (1280 x 960 pixels). Additionally, the DFK 41AU02.AS can output these high resolutions images at a speed of up to 15 frames per second. Using the shipped software - IC Capture.AS - you can capture lossless and uncompressed images sequences as AVI files.

Fast display of colour images

Using the original images from the CCD (RAW format) for visualization purposes does not make much sense. Only after colour interpolation, is it possible to view the images in common formats. The bandwidth required when transferring interpolated images is considerably broader than when transferring the original RAW formatted images. The CCD camera DFK 41AU02.AS allows colour interpolation to be switched off, thus achieving 15 colour frames per second. In this case, colour interpolation is performed by IC Capture.AS on the host computer. Alternatively, should colour interpolation not be desirable at all, AVI files can be written in RAW format.

Sony colour CCD

The astro CCD camera DFK 41AU02.AS deploys the colour CCD ICX205AK, manufactured by Sony®. This chip has a 1/2" format and 1280 x 960 pixel resolution. Even at long exposure times, its noise is minimal. Thanks to the high quality of the ICX205AK, it is often used in scientific image processing applications.

IR cut filter

Unlike the human eye, CCDs are sensitive to near infrared light (wavelengths over 700nm). It is often not desirable to capture light that is in the near infrared range. Indeed, such light often disturbs an otherwise perfect shot. Therefore, the CCD camera DFK 41AU02.AS ships with an IR cut filter.

Fast data transfer via USB 2.0

The astronomy camera DFK 41AU02.AS outputs high resolution images, without compression at high speed. This results in large amounts of data being generated. In order to transfer these to the host PC, a very fast bus is required. Hence, the camera is fitted with a USB 2.0 connector.
