Measurement of velocity, concentration and temperature in liquid flows using Laser Induced Fluorescence
Concentration measurements in liquid flows
Dantec Dynamics' liquid planar-LIF system is an optical measurement tool to acquire whole-field concentration data using the planar laser-induced fluorescence (planar-LIF) technique. Quantitative analysis are based on calibration images that map the response at every pixel of the camera with respect to both local concentration and local laser light energy.
Applications
With Dantec Dynamics' planar-LIF solutions, quantitative information can be obtained in many concentration applications, including:
The mixing performance of e.g. chemical processes
The role of coherent mixing structures on the transport of a marker
The interaction between large-scale and smaller-scale in turbulent mixing
The dispersion of pollutants in model ocean systems, etc.

The XLE4 – eXtreme Low Energy Detector
eXtreme Low Energy measurement: this is what the XLE4 stands for. From nJ’s to mJ’s, the XLE4 offers accurate NIST measurements in all conditions. It is a nice complement to our series of QE energy detectors to read even lower energies.
Low Noise Level
The XLE4 low noise equivalent energy of 30 nJ with an amplifier or 150 nJ with a SOLO sets it apart from the competition. This pyroelectric detector thus extends in the nJ’s the measurement range of QE series joulemeters. Its high sensitivity of 1100 V/J makes it ideal for measurement in noisy laser environments.
kHz Repetition Rate
The metallic coating of the XLE4 makes it an excellent choice for pulsed lasers up to 2000 Hz. It can detect pulses of duration up to 5 µs. Moreover, it can be used with many different types of lasers due to its broad spectral range.

The UP12E family was designed for portability. It is an excellent choice for field service or small beam OEM applications. The low profile stand alone detector measures a few mW to 10 W and to 20 W with its heatsink. Water cooling takes it to 70 W of continuous power. That is great for embedding in machines and immunity from environmental fluctuations. Great performance in a package as little as 14 mm deep!

The QPM Family
Gentec-EO’s QPM Series is a fully automatic laser power probe that calculates laser power by measuring temperature dynamics using a microprocessor. Its measurement and acquisition technique determines the time needed to carry out a measurement. Data acquisition is triggered and stopped by detecting set heat parameter thresholds. This technique is virtually error free and allows for multiple measurements without absorber forced cooling.
Power Range
Six models cover the full-scale powers from 500 mW to 10 kW. Their innovative measurement concept cuts the time to measure and display down to ten seconds on all probe models providing:
# Excellent accuracy (± 3 to 4%)
# Repeatability (± 1 to 2%)
# High resolution

General description :
Coherent offers the broadest line of laser power meters and laser energy meters available anywhere. In addition, as the world's leading producer of laser systems, we thoroughly understand the practical requirements and challenges of using laser measurement tools. This puts Coherent in a unique position to configure a laser measurement system that provides the right combination of performance, features and cost for your particular needs. The modularity of the Coherent system also ensures that your investment will be protected as your needs evolve or change.
Our standard product line consists of four types of meters:
- Laser Power Meters
- Laser Energy Meters
- Laser Power and Energy Meters
- OEM Power and Energy Modules
Power-only and energy-only meters offer simplicity and economy. However, certain advanced capabilities are only available in dual (power and energy) meters, so these products should be considered, even if your use is purely for a single measurement type (power or energy).
