Aici este panoplia, împreunã cu sorturile de sticlã:
The König eyepiece shown here (many other eyepiece designs are also due to Albert König) is based on the Orthoscopic design, but splits up the three-element field lens with one extra air gap, so that it consists of a single eye lens, a two-element lens in the middle, and a single field lens. This creates an additional degree of freedom for correcting abberrations, allowing the design to be modified to provide a wider field.
