Ultra Precise Eye body tubes are designed to be coupled to infinity corrected objectives when higher magnification and higher resolution imaging is required.
Fine Focus: For applications without separate moving support systems, the Ultra Fine Focus body tubes offer focus over a 3 mm Fine Focus axial distance at the object.
Coaxial Illumination: Coaxial / on axis illumination is most effective when imaging flat specular surfaces. By integrating the coaxial illumination port, a collimated, diffused and uniform illumination source is integrated into a zoom lens.
