APO-Rodagon-D

High-Performance Lenses for Large Imaging Sensors

The high resolution of the Apo-Rodagon-D lenses makes them an optimum solution for cameras with a pixel size down to 7 μm. The high resolution is accompanied by ultra-low distortions and negligible color fringing. The lenses are optimized for a magnification range from 1:2 to 2:1.

The 6-element, apochromatically corrected lenses feature high contrast and sharpness right up to the picture corners with practically no color fringes.

Distortion is corrected to near zero and cannot be seen even in critical subjects with straight-lined structures. The optimum working aperture is between f/5.6 and f/8. This is important because the effective aperture of a lens focused for a scale of about 1:1 is approximately two f-stops smaller than the nominal aperture and therefore stopping down to smaller apertures than nominal f/8 would result in visible blur due to diffraction.

All standard models are fitted with click-stop aperture rings. .
