Optical Sensor Systems

Optical Sensors for internal combustion analysis, temperature measurements and trace gas detection for leakage tests.

LaVision was founded in 1989 as a spin-off from Max Planck Institute and Laser Laboratory in Goettingen, Germany.

LaVision offers standard and dedicated customer designed Laser Imaging Systems for reactive and non-reactive flow field analysis and fluid mechanics applications, Intelligent Imaging Systems for non-destructive material testing, a range of high-performance cameras (CCDs and intensified CCDs) and smart optical sensor systems.

The LaVision team has extensive professional experience in Laser Imaging Spectroscopy and optical techniques such as Laser Induced Fluorescence (LIF), Absorption and Emission Spectroscopy, Raman, Rayleigh and Mie Scattering, Particle Image Velocimetry (PIV), Spray Analysis, Digital Image Correlation (DIC) techniques as well as ultra-fast time-resolved imaging and high-speed image recording.


LaVision is offering optical sensor systems for the following applications:

Optical Engine Indication (ICOS)
LaVision’s Internal Combustion Optical Sensors (ICOS) measure crank angle resolved air/fuel ratio, exhaust gas concentration and gas temperature locally at the spark (glow) plug or at any other in-cylinder location using optical M5-probes. Transmission probes for path integrated cross-cylinder measurements are also available.
Temperature Sensor LTS-100
For flame temperature measurements based on TDLAS absorption spectroscopy
LaVision's fiber-optics Laser Temperature Sensor LTS-100 measures gas temperatures up to 2200 °C. The sensor is well-suited for measurements in harsh environments due to its low sensitivity to particulates and other obscurities in the laser beam path.
Leakage Sensor
For trace gas detection for leakage tests
LaVision's Laser Vial Analyzer is designed to measure in-line the vacuum quality of low pressure gas containers mainly in the pharmaceutical industry.
