Microscope objective adapter rings to convert objective threads to M42 M49 M52 M58 M62 and M67 interfaces. Simple, reliable adapters that let you mount microscope objectives to equipment with standard metric thread interfaces. Key benefits Broad compatibility: Provides direct thread conversion to M42, M49, M52, M58, M62, and M67 interfaces, expanding the range of optical and imaging accessories you can use with microscope objectives. Restores functionality: Enables microscope objectives to be mounted on cameras, extension tubes, bellows, and other imaging accessories that accept standard metric threads. Secure, repeatable fit: Precision thread engagement minimizes play and helps maintain optical alignment for consistent imaging results. Compact and lightweight: Lowprofile rings keep mechanical clearance to a minimum, preserving working distance and focus range. Easy to use: Threadon installation requires no special tools. Swap adapters quickly when changing objectives or accessories. Main attributes Function: Thread conversion adapter rings for microscope objective to metric thread interfaces. Compatibility: Designed for objective threads that match the adapter inner thread and for external M42 M49 M52 M58 M62 M67 interfaces. Size: Available for conversion to M42 M49 M52 M58 M62 and M67 thread sizes. Material and finish: Metal construction for structural stability and reliable thread engagement. Performance: Precisionmachined threads for repeatable mounting, reduced lateral play, and stable optical axis alignment. Practical applications Photomacrography: Mount a microscope objective to a camera adapter or extension tube with an M52 or M42 thread to achieve magnification product or specimen photography. Laboratory and inspection setups: Integrate microscope objectives into custom rigs, machine vision systems, or quality control stations that use M58 or M62 threaded interfaces. Educational and testing use: Quickly test multiple objectives on a single imaging platform or demonstrate optical principles by swapping adapters in teaching labs. What you get A set of adapter rings that transfer microscope objective threads to standard metric interfaces, enabling flexible use of objectives across photographic and scientific equipment. Easy to install, durable in use, and designed to maintain alignment and repeatability when mounting.
