This adapter provides a simple, reliable mechanical interface for connecting a microscope to a TV or LCD monitor display. Its precise dimensions make it suitable for microscopes and video tubes that accept a 25mm upper diameter and a 28mm bottom diameter. Quantity: 1pcs. Key benefits Straightforward connection: Designed to mate microscopy optics to video display systems for quick setup and repeatable alignment. Group viewing and presentation: Enables live display on a TV or LCD monitor for teaching, demonstrations, inspections, or client reviews. Stable fit: Sized to provide a snug, stable mechanical coupling that reduces tilt and wobble during observation. Compact and lowprofile: Small footprint keeps the optical path compact and helps maintain working distance and focus settings. What it does and how it helps Function: Acts as the mechanical adapter between a microscope eyepiece or tube and a video display camera or coupler, allowing the microscope image to be shown on an external monitor. Problem solved: Removes the need to peer through the eyepiece for every viewer, improving accessibility and enabling shared observation without modifying the microscope optics. Ease of use: Simple to install and remove for fast transitions between eyepiece viewing and monitor display. Compatibility and size Upper diameter: 25mm Bottom diameter: 28mm Quantity: 1pcs Fits microscopes and couplers designed for these specific diameters; verify component sizes before to ensure compatibility. Performance and build Manufactured with precise tolerances to ensure a secure mechanical join and consistent optical alignment. Designed to minimize tilt and lateral play for reliable image presentation on a connected monitor. Typical use scenarios Classroom demonstrations: Display microscope images on a classroom TV or LCD so an instructor can share live observations with a group. Industrial inspection: Show magnified parts or solder joints on a monitor for collaborative quality checks or troubleshooting. Lab documentation and meetings: Present live samples during lab meetings or record the monitor feed for documentation purposes. Contents 1pcs adapter with Upper Dia. 25mm and Bottom Dia. 28mm Check the diameter requirements of your microscope and monitor coupler before use to ensure a proper fit.
