Laser sensors and laser triangulation sensors for maximum measurement accuracy
Laser sensors, especially laser triangulation sensors, are indispensable technologies for precise measurement applications in industry. These sensors provide accurate measurement data and enable precise distance and height measurements that are relevant for a wide range of industries - from the automotive industry and robotics to quality control and logistics.
What are laser triangulation sensors?
Laser triangulation sensors use the principle of laser triangulation to measure distances accurately. The sensor emits a laser beam onto the surface to be measured and the reflected beam is focused onto a receiver diode. The sensor calculates the distance based on the change of the angle of light - with an accuracy in the micrometer range.
Laserová triangulace - princip funkce senzorů
Triangulace znamená měření vzdálenosti pomocí výpočtu úhlu. Snímač promítá laserový bod na měřicí objekt. Odražené světlo dopadá na přijímací prvek pod určitým úhlem v závislosti na vzdálenosti. Z polohy světelného bodu na přijímači a vzdálenosti od vysílače k přijímacímu prvku se v senzoru vypočítá vzdálenost k měřicímu objektu.

FAQ
A laser triangulation sensor is a non-contact sensor for precise distance measurement. It projects a laser beam onto an object and a CMOS line detects the reflected beam at a specific angle. The sensor uses this angle to calculate the distance from the object - ideal for applications in quality assurance, automation and surface measurement. Equipped with high-quality components, laser sensors from Micro-Epsilon are extremely precise and suitable for fast measurements.
Laser sensors are used in industrial automation, quality inspection, robotics, surface inspection and position control. They are perfect for detecting height profiles, distance measurements, position detection, presence checks and thickness measurements in manufacturing processes.
The precision of a laser sensor depends on several factors, including the surface quality of the measuring object, the ambient light conditions, the measuring range and the resolution. The high-quality triangulation sensors from Micro-Epsilon offer special filter and compensation functions to deliver accurate results even under difficult conditions.
Laser triangulation sensors are extremely precise, work without contact and are suitable for a wide range of materials and surfaces, even in fast production processes. They offer high measurement speed, are wear-free and provide reliable results, even in difficult lighting conditions. Another advantage is the large variety of measuring ranges - from a few millimeters up to 1 m measuring range can be realized with the laser triangulation sensors from Micro-Epsilon.
Most laser triangulation sensors use class 2 lasers, for which no special protective measures apply. Protective measures are required for more powerful lasers (e.g. class 3R or higher). Ask us about the most suitable laser class for your measurement task.
