Features: -When you are looking for an advanced level of microscopes, there are certain features you need and some features you'd like as options. Weve taken all of them into consideration, when building our medical microscope. We began with four achromatic building parfocal objectives 5x, 10x, 45x (SL) &100x (SL) or four achromatic coated par focal objective 4x, 10x, 40x (SL) & 100x (SL). Addition of stain free WF eyepiece 10x gives large field of view. Rubber feet at the bottom provides positive grip. The body is Aluminium cast metal for durability and finished in black enamel paint.
