Deep UV Lasers and Controllers


Pulsed Deep UV Lasers

Pulsed Deep UV Lasers

The DUV family of lasers are affordable and offer 224.3nm and 248.6nm.
Technology From: Photon Systems

Pulsed Deep UV Lasers

Power Output: Over 100mW
Wavelengths: 224.3nm, 248.6nm

The DUV

Deep Ultraviolet
family of lasers are affordable and offer 224.3nm and 248.6nm. The laser is the size, weight and power consumption of a HeNe laser but with output in the deep UV. The self-contained, integrated, laser controller enables remote computer control for ease of operation and flexible data collection via LabView software. With an input power less than 10W the need for water cooling and other thermal management issues is eliminated.

The lasers reach full power in less than 20 microseconds from a cold start from any ambient temperature from -200 to 100°C without preheating or temperature regulation. With output over 100mW and line widths less than 3GHz or 0.0005nm these are great sources for a wide range of applications.

Targeted Ultraviolet Chemical Sensor (TUCS)

Targeted Ultraviolet Chemical Sensor (TUCS)

Targeted Ultraviolet Chemical Sensors (TUCS) are in-situ, non-contact, non-invasive, non-destructive sensors that require no sample handling or preparation.
Technology From: Photon Systems

Targeted Ultraviolet Chemical Sensor (TUCS)

Targeted Ultraviolet Chemical Sensors (TUCS) are in-situ, non-contact, non-invasive, non-destructive sensors that require no sample handling or preparation. They employ UV

Ultraviolet
laser induced native fluorescence and resonance Raman spectroscopy to detect and classify unknown molecules and molecular structures. By employing deep UV excitation wavelengths the need for tagging target materials with dyes is eliminated.

Dye tags are a significant source of error in many measurements and can obscure the chemistry being measured. Using excitation wavelengths below 250nm, native or endogenous fluorescence and UV Raman emission of target molecules can be measured simultaneously without mutual interference.
