Imaging using the "large" Lieberkuhn objective lens. Total magnification is approximately 70x.
Imaging using objective "2". This lens may have been used in "dissecting" mode only. Total magnification is approximately 45x.
Imaging the stage micrometer. Resolution using the "large" Lieberkuhn objective is approximately 10µm.
Imaging the stage micrometer. Resolution using Objective "2" is 20–50µm. Note the spherical aberration and vignetting.
