Aluminium M42 RMS Objective Mount Ring

High-tolerance M42-to-RMS adapter ring manufactured from aerospace-grade aluminium alloy. External M42 × 1 mm male thread interfaces with standard M42-mount objectives or extension tubes; internal RMS (0.796"–36 TPI) female thread accepts RMS-standard microscope objectives. Measured outer diameter: 42.0 ± 0.1 mm; thickness: 5.5 ± 0.1 mm; weight: 17.8 g. No optical glass, no coatings, no electrical components. Intended exclusively as a mechanical interface — does not enable autofocus, automatic aperture control, or infinity focus. Compatible only when used in conjunction with a separate SLR/mirrorless lens mount adapter (e.g., Canon EF, Nikon F, Sony E). Total optical path length (objective back focal plane to sensor) must be ≤160 mm to achieve focus — users must calculate spacing carefully using flange distances of their camera system and any intermediate adapters. Working distances remain unchanged from the objective’s native specification: ~12 mm for 4×, ~1.5 mm for 10×, ~0.6 mm for 20×. Image circle coverage may show mild edge softness — inherent to microscope objective design and not indicative of adapter quality. Ideal for scientific documentation, PCB inspection, botanical imaging, and educational microscopy labs.
