National 411TBL-10 overview

  • 1Description

The 411-TBL-10 Stereoscopic Microscope from National Optical is a versatile user-friendly stereoscopic optical instrument designed to facilitate teaching at the high school level and is also capable of handling a wide range of tasks for hobbyists and researchers alike.
