Lansis Camera
Lansis cameras, illustrated in
, are fully integrated camera systems. The
camera contains all of the electronics necessary to read out and control the CCD
device. For instance, it houses precision analog-to-digital converters (ADCs) positioned
close to the CCD for lowest noise and has USB 3.0 electronics to interface with the host
computer.
Figure 2-2: Typical Lansis Cameras
Lansis camera systems offer all basic CCD camera functions, such as Region of Interest
(ROI) selection and binning, all under software control. It also provides advanced
triggered operation as well as programmable TTL output.
Among the many state-of-the-art features are its maintenance-free permanent
vacuum, integrated controller, deep thermoelectric air-cooling, and compact design.

eXcelon
®
eXcelon is a CCD/EMCCD sensor technology jointly developed by Teledyne Princeton
Instruments, Teledyne e2v, and Teledyne Photometrics
®
. Spectroscopy CCDs using this
technology provide the following significant benefits:
•
Improved Sensitivity
Improved QE over broader wavelength region compared with back-illuminated
sensors.
•
Reduced Etaloning
Up to 10 times lower etaloning or unwanted fringes in near infrared (NIR) region
compared with standard back-illuminated CCDs.
