D4H

Overview

• UV/VIS/NIR continuous fiber optic light source
• Wavelength range: 200-1700nm
• Integrated shutter with switch and TTL control
• SMA fiber optic connection
• Separate UV and VIS bulb control
• High output: twice the intensity (compared to conventional models)
• High stability
• Long Life Lamp: 2000 hours
• External Control
• Shutter Function

The D4H is a combined deuterium and halogen light source for UV/VIS and NIR applications. This light source is ideally suited to work with WPI’s spectrometer modules and sample cells. It supplies a continuous spectrum in the UV, VIS and NIR range from 200 nm to 1700 nm. The D4H is equipped with an integrated electrical shutter, which can be controlled by a switch or a TTL signal.

Benefits

• Matched deuterium and halogen bulbs
• Matched optical output for WPI's flow cells and fiber optic probes
• Ultra Low drift < 1 mAU/h @ 254 nm
• Simple exchange of light bulbs

Applications

• UV/VIS/NIR absorbance spectroscopy
• Excitation light source for fluorescence applications
• Colored Dissolved Organic Matter (CDOM) detection in seawater
• Nutrient Analysis in fresh water, drinking water and seawater using WPI's LWCCs
• Protein detection using WPI's V-Vette or DIP UV MINI fiber optic probes
