<p>Revision 0.3!</p> <p>This is an adapter to use M12 lenses (S-mount, board lenses) as RMS microscope objectives.<br/> It is composed of 4 parts (plus the lens) that screw together.</p> <p>The lens is mounted inverted; M12 lenses between 8 and 16 mm make decent, medium-power plan objectives. Nominally they are infinity-corrected, but they work ok also for 160mm finite sistems.<br/> Max diameter of the M12 lens to fit is 16mm if short, 19mm if tall.<br/> The adapter with the lens mounted then looks and works as a microscope objective.</p> <p>You need to print 4 (small) pieces:</p> <ul> <li>RMS Objective holedr (barrel)<br/> -M12_Objective_top<br/> -M12_nut</li> <li><p>M12 Objective Iris, choose the one you want (4mm default) This design is made to be parfocal with objectives 35-38mm.<br/> Fine-tuning of the parfocality is done by screwing the M12 lens at the right position (trial-and-error) and then fasten it from the outside with the nut.</p> <p>Print them with high resolution<br/> The photos of the make here are from a previous version.<br/> In Rev.2 I moved the bottom cap inside, and made the RMS thread with slightly looser tolerance.<br/> Rev. 3 Put the wings on the nut, added the iris and the cutout drawing.</p> <p>Still no OpenSCAD, so you can enjoy those 4MB .stl</p> <h3>Print Settings</h3> </li> </ul> <p><strong>Rafts:</strong></p> <p>Yes</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0,1</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>100</p></div><br/> <strong>Filament:</strong><br/> Ultimaker PLA Black <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>PLA worked fine for me.
