The following is an announcement from Kevin Nelson of QSI, regarding the new QSI 540 which you'll be able to see at the conference (in addition to their other cameras). ----------------------------------------------------- QSI Introduces the 540 and 540c with larger 4.2mp mono or color sensor The QSI 540 employs the 4.2 megapixel Kodak KAI-04022 interline transfer sensor with microlens technology. The compact design of the QSI 500 Series allows the 540 to set a new benchmark for size and cost in a high performance, full-featured scientific CCD camera with this large 4.2mp sensor. Introductory pricing starts at $3,995. Deliveries will begin this month. A total of five configurations of the monochrome QSI 540 and color 540c are available. The slim body QSI 540i and 540ci utilize the electronic shutter built into the KAI-04022 image sensor to control exposures. The 540si and 540csi incorporate the optional internal mechanical shutter in the mid-size body to simplify the creation of dark and bias frames. The full-size 540wsi adds a 5-position internal color filter wheel that holds standard 1.25" filters. Because the internal color filter wheel is positioned very close to the focal plane in the QSI 540wsi, the 21.4mm diagonal Kodak KAI-04022 sensor experiences no optical vignetting through standard 1.25" filters, even with fast optical systems down below f/4.5. Even below f/4 the very small amount of light drop-off in the extreme corners of the large 2K x 2K sensor is almost undetectable and easily corrected with routine flat field calibration. Without filters, the 540si works with optical systems down below f/2.3, and the electronic shuttered 540i and 540ci below f/1. We've posted an LRGB image of the North America Nebula captured by Alan Smallbone with the 540wsi with a 5" Borg at f/3.9. No flat field calibration was applied. http://www.qsimaging.com/gallery.html Complete details on the monochrome 540 and single-shot-color 540c can be found on our web site: QSI 540 - http://www.qsimaging.com/540overview.html QSI 540c - http://www.qsimaging.com/540coverview.html Regards, Kevin Nelson Quantum Scientific Imaging www.QSImaging.com |
