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 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.
