Planachromatic objective for observations in polarized transmitted light. The lenses of the polarizing objective are designed to create neither distortion nor birefringence within the optical system. Objectives with planachromatic optics create a sharp image both in the centre and on the sides. This is achieved by correcting geometric aberration by more than 90% of the visible field area. Therefore, they combine perfectly with a digital camera or eyepieces with a large field of view. T...
