Color Viewer 10X lens

Using the same high quality optical design as the Betamag 10, this lens is mounted in an extended barrel to exclude ambient light. It has an external focussing thread to adjust it to your vision and a locking ring to prevent accidental change. It fits directly into the body of the Beta Color Viewer Model I and II and threads into the magnetic lens plate for use with the Model III. Order the lens plate separately as needed.
