The available space in the machine, and therefore the maximum length and diameter of the objective lens, was a fixed factor in this project. Despite this very limited space, the highest possible optical resolution was required. All requirements were met thanks to a perfect combination of optical design, mechanical mounts, and alignment to achieve a detail resolution of up to 1.5 µm.

• Modulation Transfer Function (MTF) at a
  wavelength of 460 nm.
• The resolution of the objective lens is very close to the diffraction limit, even in the corners of the sensor.
• It can resolve structures up to 1.5 µm.

The optics are fitted with coaxial illumination in the form of a RGBW-LED (460/525/625 nm wavelengths) i9. An appropriate illumination unit illuminates the field of view extremely homogeneously. The deviation from the medium intensity is less than 5%.
