In addition to point and line projections, a variety of other projection
patterns are used for camera applications: crosses, circles, squares, point
matrixes, multilines, chessboard patterns and many others. These projections
are created by means of diffractive optical elements (DOEs). DOEs are based on
the principle of bending light around periodic microstructures. With
appropriate surface structure design, beam-shaping features such as computer-
generated holograms or freeform phase functions can be implemented. In
addition to standard projections such as crosses, multilines, chessboard
patterns, circles and so on, we can also offer custom DOEs.
The ZM18-X diode laser is a robust laser with a cross lens. Its optics can be
focused easily and very well without changing the rotation position and the
laser image position.
Three different versions are available depending on the application
The base model is characterized by its simple handling. It is easily shiftable
but without intensity adjustment nor triggering.
With the standard model the intensity can be adjusted. It is equipped with an
analog modulation an a digital TTL trigger with a switching frequency of up to
500 kHz. This option allows to adjust the intensity and to switch the laser in
The high end model offers all characteristics of the standard models but the
frequency of the TTL trigger is up to 100 kHz.
Digital modulation 5V (DM53)
This model has a trigger frequency of up to 100 kHz without analogue intensity control. The power supply is 4-6V. The DM53 is the shortest laser of the ZM18 series.
All lasers are available in the colors red an infrared. The high end version
is also available with a blue diode and the base version with a green diode.
For each colour different wavelengths can be chosen.
There are also available different output powers. These depend on the laser
wavelength and go up to 200 mW.
The Z-laser diode lasers are installed in a compact, water resistant IP67
housing. A M18 male thread for standard sensor supports and a supply voltage
between 5 VDC and 30 VDC (between 4 VDC and 6 VDC for the DM53 version) allow a very easy integration.
