Advanced technology delivers ultra-high speed and stability
The LJ-V7000 Series is the first 3D laser inspection system in the world to utilize a blue laser. A sharp line beam is formed on the light-receiving element by focusing a short wavelength (405nm) laser to its diffraction limit with a 2D Ernostar lens. This generates a stabilized high-precision profile ensuring optimal accuracy and limiting image blur. Also, the output intensity of the laser source has been optimized to provide a clear return even on targets with a wide range of reflectivities.
A laser beam that has been expanded into a line is diffusely reflected from the surface of the target. This reflected light is formed on the HSE3-CMOS and by detecting changes in the position and shape of the reflection, it is possible to measure the position of various points along the surface of the target.
