High Performance, Low Cost 3D Profile Sensor

High-Performance 3D Profiler Sensor for In-Line Measurement and Inspection Applications

Z-Trak is a series of 3D profile sensors delivering high-resolution, real-time height measurements using laser triangulation. These lightweight IP67 rated profile sensors are ideal for in-line measurement, inspection, identification and guidance applications in automotive, electronics, semiconductor and factory automation.

Z-Trak series delivers reliable and repeatable results in varying operating conditions. Z-Trak models handle object widths from 8.5 mm to 1520 mm and height range of 10 mm to 1000 mm. All Z-Trak models are factory calibrated and come with a choice of laser options to suit the surface reflectance.

Z-Trak series features real-time laser line optimization for uniform measurement results, multi-sensor synchronization using generic Gigabit network routers and Power-Over-Ethernet (POE) to simplify setup and configuration. Z-Trak series comes bundled with Teledyne DALSA’s field-proven software packages – Sapera LT, Sapera Processing, and Sherlock 8 3D – at no extra cost. In addition, Z-Trak sensors can operate with 3rd party software packages using either GenICam® or proprietary interfaces.

Powerful. Versatile. Easy to Integrate.

All Z-Trak models are factory calibrated and include powerful features such as FIR-peak detector, optimized optical design, adaptive laser control to optimize integration time, field proven software libraries, and many more.

The overall result? A high-accuracy, high-resolution 3D laser profiler at a low total-cost of ownership.

How exactly does 3D imaging work?

There are a number of techniques available for 3D imaging. The Z-Trak series of 3D laser profilers uses a laser triangulation technique to deliver high resolution height measurements. Z-Trak emits a laser onto an object of interest; the reflection's position in the sensor's field of view allows the scanner to triangulate the point in space at which the laser hits the object. 

The diagram at the left illustrates the terms we use to specify Z-Trak's performance.
