Raynox DCR 150 Schneider Kreuznach Componon 210 Novoflex Micro Tube and a Chinese-made ITL-200 clone A tube lens is the optical component that makes it possible to use infinity-corrected microscope objectives. Such objectives do not form a direct image; instead, they emit a parallel bundle of light. The tube lens collects this parallel light and projects it onto the camera sensor—forming the image on the sensor. In simplified terms, the microscope objective determines resolut

Raynox DCR 150 Schneider Kreuznach Componon 210 Novoflex Micro Tube sowie eine chinesische ITL-200-Kopie Eine Tubuslinse ist das optische Bauteil, das die Arbeit mit unendlich korrigierten Mikroskopobjektiven überhaupt erst ermöglicht. Solche Objektive erzeugen nicht ein direktes Bild, sondern geben ein parallel verlaufendes Lichtbündel ab. Die Tubuslinse sammelt dieses parallele Licht und projiziert es auf den Kamerasensor – erst dadurch entsteht ein sichtbares Bild. Vereinf

Iris photographs are usually created from single images. In certain problem cases, however, focus stacking can help to achieve greater depth of field. This article explains how. Iris photography is currently experiencing a real boom. That has a lot to do with its visual appeal – but even more with a simple realization: the human iris is astonishingly individual. No two irises are alike. Colors, structures, lines, and speckles are as unique as a fingerprint. And the closer you
