Product name: microscope objective adapter ring Size: M26 to RMS Material: Aluminum, anodized black Color: Black matte What this adapter ring does Converts objective threads so microscope objectives and camera adapters can be fitted together securely. Provides a precise, low profile mechanical connection that maintains optical alignment between objective and mount. Works across a broad set of common microscope and camera thread standards to increase compatibility without modifying equipment. Key benefits Improve compatibility: lets you use objectives and accessories with different thread standards, avoiding the need to optics or specialized mounts. Durable and stable: CNC machined from aluminum and anodized for a hard matte finish that resists wear and reduces stray reflections. Precise fit: accurately cut threads and close tolerances minimize play and preserve optical alignment for imaging and observation. Lightweight and low profile: adds minimal extension so working distance and focus are affected as little as possible. Wide model selection: multiple adapter options and pitch variants allow matching to the exact thread specification you need. Important attributes Material and finish: aluminum construction with black anodized matte finish for durability and low reflectance. Function: mechanical thread conversion between microscope objectives, camera adapters, and mounts. Compatibility and sizes: supports a variety of thread conversions including M26 and RMS standards and multiple M42 variants with specified pitch options. Performance: stable, repeatable connections suitable for imaging, inspection, and laboratory use. Available models M42 to CS, M25 to RMS, RMS to M25, M42 to RMS (Pitch 0.75), M42 to RMS (Pitch 1), RMS to M26, M26 to RMS, RMS to M27, M27 to RMS, M40 to M26, RMS to CS, CS to RMS Typical use scenarios Laboratory imaging: attach an RMS objective to a camera or adapter with an M26 or M42 thread to capture photomicrographs without changing optics. Field or industrial inspection: adapt a microscope objective to an inspection camera or borescope with a different thread standard for onsite materials inspection. Educational and hobby projects: mix and match legacy objectives and modern camera adapters to expand the functionality of classroom microscopes and DIY imaging rigs. Why choose this adapter ring Straightforward, mechanical solution to thread mismatches that preserves optical alignment. Multiple specific model choices, including pitch variations for M42 to RMS, ensure a precise match to your equipment. Robust aluminum construction and anodized black finish balance durability with low reflectivity for imaging work. Notes Select the model with the correct thread combination and pitch for your components to ensure proper fit and function.
