Laser and Photodetector Cooling with Norhof LN2 Auto-Fill Systems
Precision, stability, and reliability are critical when cooling sensitive laser and photodetector setups. Norhof’s LN2 auto-fill systems ensure your high-performance detectors and laser sensors receive continuous, gentle, and vibration-free cooling using liquid nitrogen—without the hassle and safety risks of manual refilling.
Our LN2 microdosing technology delivers low-pressure (max 300 mBar) liquid nitrogen directly from a storage Dewar, providing an automatic and highly controlled fill process, perfectly suited for:
- – Infrared (IR/MIR/FIR) laser detectors requiring cryogenic temperatures
- – FTIR and advanced spectroscopy detector Dewars
- – Scientific photodetectors in research labs and universities
- – High-sensitivity imaging and low-background measurement systems

Custom Made Adapters
LN2-cooled spectroscopy cameras from leading manufacturers can be equipped with Norhof auto-fill to keep their detector Dewars safely and continuously supplied with liquid nitrogen for long, low-noise measurements.
- – Horiba Symphony II cryogenic CCD detectors (1 L and 3 L LN2 side-looking Dewars) – ideal for Norhof LN2 auto-fill to ensure stable detector temperature during extended spectroscopy runs.
- – Princeton Instruments LN2-cooled spectroscopy cameras (such as PyLoN and legacy LN2-cooled CCD/InGaAs systems) – Norhof auto-fill maintains a constant LN2 level in the detector Dewar for ultra-low-noise Raman, PL, and UV-VIS-NIR measurements.
- – Nüvü EM N2 liquid-nitrogen-cooled EMCCD/CCD cameras – perfectly matched with Norhof LN2 auto-fill for very long exposure times and minimal dark noise in demanding imaging setups.
- – IRCameras / Axiom Optics LN2-cooled MWIR scientific cameras (e.g. IRC800 series InSb and nBn systems) – Norhof LN2 auto-fill supports reliable, vibration-free cryogenic cooling of the integrated detector Dewars.
