LQ-HXP 120


External Light Source for Fluorescence Excitation Microscopy

This compact device is the ideal illumination source for fluorescence excitation in microscopy. Coupling is preferably achieved via liquid light guides to reduce heat at the microscope and to allow for remote shuttering of the lamp, reducing potential vibrations during time-lapse imaging. The average service life of a lamp is 2,000 hours. The optimized internal air flow cools the lamp and enables quiet operation. A resettable operating hour meter shows lamp operating hours. The brightness of the lamp output can be varied in 5 steps (0-100%) by means of a mechanical dimmer unit. An ultra-fast shutter opens or closes after activation with approx. 6 ms. The shutter is actuated either by means of an appliance switch, or externally by means of a remote control input or CAN-BUS connection. This compact light source is available as a VIS or UV version in addition to a version that permits the coupling of multi-pin liquid light guides.
