The inspec.x L series was developed to meet the highest requirements in the field of industrial image processing. This series has outstanding image performance over an image circle of up to 82mm. This is realized via a diffraction limited optical design and a highly demanding mechanical manufacturing process. The V-Groove enables that the lens can be adjusted to their best azimuth position and it is also possible to use the lens in retro position. The inspec.x L series covers a large magnification range from infinity to enlargement of 5:1. Through the newly developed prism module and the adjusted optical lens design, is it now possible to use coaxial illumination for line sensors without performance loss.
