Buying Distance Measurements with Lasers
Lasers can be used in various ways to measure distances or displacements without physical contact. They enable highly sensitive and precise length measurements, fast recordings, and large measurement ranges, using methods such as triangulation, time of flight, phase shift, and interferometry.

TOPTICA Photonics AGLochhamer Schlag 19 82166 Gräfelfing Germany See us at SPIE Photonics West 2025 in San Francisco, January 25–30 (booth 1527, 3501, 3603)! |  Laser rangefinders can be used to monitor or measure distances or object lengths. They can also provide positional locations over long distances, e.g. several kilometers, without physically touching the observed object. The laser range finders are regularly used in geodesy, sports, hunting or military. Usually, the distances are measured with accuracies of up to a millimeter, whereas the measured object can even be in motion. In addition, measurements on natural surfaces with low reflectivity are also possible. The Beam smart WS is the ultimate choice when looking for a compact and narrow linewidth OEM diode laser system. It is the wavelength stabilized version of the iBeam smart featuring reliable wavelength-stabilized diodes. Combined with iBeam smart’s flexible, microprocessor based electronics it makes system integration a snap. |
