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

Sensitivity

Laser excitation

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

 

Quantification

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

 

User friendliness

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
