Dark Field科技采用Nxt ReflecXun技术，这种系统能够检测发光的金属线圈。GIGS组件在金属基层的生产取决于原始的线圈品质，公司称，通过分流和切割线圈，对线圈造成的挤压，碰撞，夹杂物，刮伤都会减损使用效率。
Dark Field Technologies has introduced NxtGen ReflecXun, a system for the in-line inspection of shiny metal coils. The production of copper indium gallium diselenide (CIGS) modules on metal substrates depends upon pristine coil quality, the company explains. Scratches, inclusions, bumps and dents in the coil translate into efficiency losses due to shunts and shorts. The strip surface must be blemish-free and smooth.
Traditional vision systems cannot meet these challenges, as they are not designed to inspect shiny surfaces (Ra <25nm) for defects of 2µm - 10µm and greater, according to the company. NxtGen ReflecXun system utilizes proprietary dark field optics and high-speed scan cameras to detect scratches and other defects. The systems are 100% solid state, self-aligning and maintenance-free, Dark Field Technologies notes.
