Alrad has introduced the StingRay range of diode laser-based line generators from Coherent. The laser line generators are ideal for making 3D triangulation measurements.
The StingRay series mates a diode laser with high-performance electronics and precision refractive optics for collimation and line generation covering a wide range of fan angles. The lasers also incorporate optional diffractive elements for creating complex output patterns. StingRay models are available with output powers as high as 200mW, at key wavelengths from 514nm to 830nm including the popular 635nm and 660nm lines.
StingRay lasers offer a line intensity non-uniformity down to ±5 per cent in a standard product. This high uniformity reduces the need for image post-processing and translates directly into increased measurement speed and dimensional accuracy.
StingRay lasers offer external user focusable optics, which allow the laser line to be optimised for the exact distance over which it is projected. Additionally, the StingRay’s opto-mechanical design permits dynamic line balancing, enabling simple correction of any intensity bias in configurations where the laser must be used at off-axis illumination angles. To further enhance usability, StingRay lasers also include an internal health monitor that indicates when a diode is approaching the end of its life, thus allowing for planned replacement and avoiding production downtime due to an unexpected failure.
