F-mount/C-mount lens coupler / telescope / beam expander

prusaprinters

<p>This is an optical mount which allows the coupling of a Nikon F-mount lens to a C-mount lens. The spacing between the mounts matches the combined flange length of the F and C mount lenses, so that the focal point of each lens is in the same plane. As a result, with both lenses focused on infinity, connecting two lenses with different focal lengths with this coupler is a simple way to create a telescope or laser beam expander.</p> <p>The model includes multiple holes suitable for attaching M6 threaded screws, and 4 foles on the F-mount side allow the insertion of alignment rods (e.g. Thorlabs cage rods) to simplify alignment of multiple telescopes. The F mount side includes a notch for the aperture lever for Nikon lenses without an aperture ring.</p> <p>The attached photographs show the coupler with a 12mm Edmund Otpics lens attached to a 50mm Nikon AF-S 1.8G lens.</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Prusa</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>I3 MK3S</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div></p> <p><strong>Notes:</strong></p> <p>The model prints well with support when printed with the C-mount side on the bottom. If the slicer allows, place a support blocker in the mount holes as support isn't needed here and removal can be tricky (PrusaSlicer allows the insertion of support blocker for example).</p> <p>We printed this with a 0.6mm nozzle, but there should be no problem with a 0.4mm nozzle instead.</p> </p></p> Category: Physics & Astronomy
