One of the quickest way to acurately check a lens is to use it as a projector lens and see the results of the projection. The new Denz Portable Lens Projector lets you do just that.
The DENZ PLC is a LED projector for checking the resolution and the focal length of lenses right up to the full format.
A precisely positioned new test slide (DENZ CHART – Klick for zoom) can be used to check the focal length of the lens. For this, the position is read directly from the dial to <0.01mm.
Likewise, sharpeness of the center / edge, image distortion, homogeneity, lens marking of the distance and “pumping” can be tested in analogy to a commercially available stand projector.
The DENZ chart offers classical linepairs (from 12-200lp / mm) and Siemens star, where the image resolution is directly readable – even anamorphic 2: 1!The DENZ chart incorporates all modern sensor sizes: 1 “, MFT, APS-C, Super35, RED Helium, full format. Despite all compactness, great importance is placed on user-friendliness and usability.
For dark test rooms, there is a working light (gooseneck lamp with 20cm/7,87”) included and the leveling lantern is illuminated. Additional equipment can be attached to the flash shoe, while the standard 24V power supply reliably hangs on the tripod. The DENZ PLC can be screwed to three ¼ “ threads on the bottom, providing the necessary stability for heavy lenses. As an optional accessory, DENZ offers the support system DAVID or the DENZ DSLR support. A solid carrying handle completes a comfortable handling.
