Product Family ZX20

The high-precision laser module
The structured light laser ZX20 sets new standards for machine
vision illumination due to its automated production in which
all optical components are aligned by a high-accurracy robot.

The ZX-laser reaches an unrivalled accuracy with its boresight

error of less than 0.8 mrad.

The user can choose from IR, red, green, or blue wavelengths
depending on the application and material to be inspected.
The right working distance can easily be adjusted with the
tool-free manual focus option.

The ZX20 with its industrial-suited design and stable perfor-

mance works perfectly as an integrated module in machine
vision aplications, sensors, or processing machines. Wavelength: 405 nm 450 nm 520 nm 638 - 785 nm 830 nm

Optical configurations for several line settings are available.

- flp** = fine line Powell; thin lines for all working distances with smaller depth of focus (recommended for fan angles between 5° -
60° at working
distances < 500 mm and for fan angle of 90° at working distances > 500 mm). This optical configuration cannot supply the maxi-
mum output mentioned on page 2. Only approx. 75% can be achieved.
- elp** = extended line Powell; lines with advanced depth of focus and thicker lines. Recommended for fan angles > 75° at working
distances < 500 mm.
The graphs above show the values for line width and depth of focus of a 660 nm laser. To get the values for a different wavelength
the factor from the table above has to be multiplied by the values from the graphs.
Example: 660 nm laser focused at 500 mm working distance: line width approx. 150 µm (@ elp** optic); Depth of focus approx.
175 mm (values from the graphs)
Calculated: 405 nm laser focused at 500 mm working distance: line width approx. 150 µm x 0.82 = 123 µm; Depth of focus approx.
175 mm x 1.02 = 179 mm
