With the ilumVision industrial IMM Photonics presents a series of laser diode modules for machine vision applications. The modules are set to a fixed focal distance, which can be adjusted to customer requirements by the manufacturer. The lasers boast either homogeneous line optics or DOE. The DOE can be used to map patterns such as multi-lines, crosses, dot matrices, viewfinders or concentric circles. The module may be digitally modulated from DC to 500kHz (positive or negative analogue modulation is offered upon request) and are currently available with a wavelength of 660nm and an output power of up to 85mW with the homogeneous line and up to 65mW when using the DOEs.
Chromasens has introduced a 3D inspection system designed for detecting imperfections on the surface of metal cylinder heads requiring large field of views.
