Apo-Rodagon D Lenses by Qioptiq

High Performance Lenses for Large Imaging Sensors and Line-Scan applications

Their high resolution makes the Apo-Rodagon-D lenses the ideal solution for cameras with a resolution of up to 7 µm pixel size. Matched to a magnification range of 1:2 to 2:1, these lenses are also characterized by minimal distortion and color errors.

The lenses consist of 6 lens elements, are apochromatically corrected and achieve outstanding contrast and excellent sharpness right into the corners of the image, practically without any color fringing. Due to the distortion almost at zero, this is not noticeable even with demanding objects with straight structures.

The optimal aperture of a lens with an image scale of 1:1 is approximately two aperture steps smaller than the nominal aperture, which for the Apo-Rodagon D is between f/5.6 and f/8. It is important to know this lens behavior, because stopping down the lens further than the nominal f-stop f/8 would produce a visible blurring due to diffraction.

The standard models have a rasterized iris diaphragm while the metal version has a continuously adjustable iris diaphragm with clamping screws.
