Levenhuk Microscope Discovery Femto Polar with book
The Discovery Femto Polar is a classic, monocular microscope that enables the examination of the microbial world in transmitted and reflected light with a magnification of 40x-400x. It can show plant and insect cell structure, life in a drop of water, protozoa, and much more. The microscope is an excellent classroom assistant for conducting simple biology experiments. An informative book about the microbial world is included. It makes experiments even more interesting and diverse.
Description
Achromatic optics enable a clear and detailed visualization of specimens. The device’s rotating head comes with three objectives: 4x, 10x, and 40x spring. The wide-field eyepiece provides clear viewing at 10x. The monocular head is inclined at an ergonomic 45° thereby making long periods of observation more comfortable. In addition, the head rotates 360 degrees above the horizontal plane, which is great for group experiments. The microscope doesn’t require moving to share an image with a partner as the head can be turned accordingly. It comes equipped with separate coarse and fine focusing knobs, thereby making the adjustment of the resolution smoother.
The illumination system consists of upper and lower LED illumination with brightness adjustment. The lower light enters through the disc diaphragm which also helps control brightness. The device can be powered by batteries (not included in kit) or plug-in (AC adapter included in kit). The stage comes equipped with clips for fixating slides.
The book entitled "The Invisible World" is a fascinating compliment to the microscope. It reveals the microbial world and scientific experiments. It is written with easy to understand language and vivid illustrations. Historical facts about microscopy and microorganisms are provided as well as experiments that can be conducted in a home setting using the Discovery Femto Polar microscope.
