The 131-CLED-MS Compound Microscope from National Optical is a versatile user-friendly compound microscope designed to facilitate teaching at the high school level using the standard format used in schools through grade twelve. This updated model features an LED stage illumination system for long-life and minimal heat output. The student-proof design decreases the likelihood of lost parts or mishandling.
This model of the 131-CLED is configured with an inclined 10x eyepiece for easy viewing when seated, achromatic 4x/10x/40x objectives mounted on a rotating turret, and low position knobs for precise focusing between coarse and fine focus ranges.
