Kaer Imaging System
OPEN FLUORESCENCE IMAGING SYSTEM
The Kaer Imaging System is a stand alone Open Fluorescence In Vivo Imaging System. It is designed for the detection of near infrared fluorescent molecules in animals in real time. Its optical head can be hand held or fixed on a stand, depending on the setup of the study. The system can be used on both small and large animals and is adapted to intraoperative imaging.
The system is designed for preclinical research only and should not be used for clinical use

Excitation type: laser
Field of view: 6.4 x 6.4 cm2
Image size (pixels): 1024 x 1024
Number of bits: 16
Image format: TIFF
Export format: AVI
Optical head - hand held or fixed on a stand
Can be controlled by a laptop
High power due to limited working distance
Dedicated filters to maximize sensitivity for a given wavelength (no filter wheel)
Near infrared fluorescence for better tissue propagation
Background recording and subtraction from fluorescence signal in real time
Pseudo colors and overlay in real time for easier image interpretation
Linear detection for quantification of the signal
High dynamic range of the detector, for quantification of weak and strong signals
On the fly quantification of ROI: histograms and signal kinetics
Tif image format recording for post acquisition quantification
Very easy to install and use
Only one parameter to adjust to optimize image quality and sensitivity
No proprietary image format, post acquisition analysis is possible with any scientific image processing software
