Laser diode module for machine vision applications

The laser diode modules are set to a fixed focus distance, which can be adjusted to customer requirements at the factory. The lasers are available either with homogeneous line optics or with DOE (diffractive optical element). Patterns such as multi-lines, crosses, dot matrices, viewfinders or concentric circles can be displayed via the DOE.

The laser diode module can be digitally modulated from DC to 500 kHz. A positive or negative analogue modulation is offered as an option.

The modules are currently available with a wavelength of 660 nm and an output power of up to 85 mW for the homogeneous line and up to 65 mW when using the DOEs.
