Alrad has announced that it is now distributing Coherent's Lasiris line of lasers for machine vision applications in the British Isles. The Lasiris range of structured light lasers offer structured light patterns including single and multiple laser lines with uniformity down to ±15 per cent. Fan angle and working distance can be tailored to match each application.
According to Alrad, the distinguishing characteristic of the SNF type laser compared to lasers with cylindrical optics is the evenness of the illumination pattern. Lasiris lasers incorporate an optical line generator that eliminates Gaussian distribution of the light, resulting in a uniform laser lines on the market. The design provides superior quality light patterns while avoiding the intricacies of installation alignment and detector calibration. Other light patterns such as square, circles, dotted lines; grid or cross hair are also available.
Coherent's Lasiris Magnum laser is a high-power (up to 7W) line generator developed for the most demanding industrial applications. It is available with a wide selection of output powers and fan angles and generates a uniform intensity distribution using line generating optics. In addition, the laser has high beam pointing and focusing stabilities. The Magnum II has fully protected electronics as well as a bipolar thermoelectric cooler used to keep the laser diode at a constant temperature. The laser beam can be adjusted by an external signal and all models can operate in either CW or external modulation mode.
Lasiris SNF and Magnum II lasers are ideal for a wide range of Image analysis applications including 3D contour mapping and profiling, high precision surface analysis, web inspection etc.
