The present invention relates to an LED microscope learning tool using a high absorbable resin, wherein a structure of a microscope is simplified, so that a learner can easily understand a structure of a phase microscope and the principles thereof and can directly observe a cell nucleus without coloring a plant cell. In the present invention, a high absorbable resin bead or semi-sphere which is a polymer compound that can be easily obtained from a stationery store is used a lens. A high absorbable resin is a resin for absorbing water as much as several tens to hundreds of times of a self weight. The material thereof absorbs water, and an absorption amount is high compared to cotton wool or cloth sewing. Water is not usually discharged by pressure. Moreover, the same has a shape of a transparent sphere to have an effective value as a lens of a magnifier. A size thereof can be freely changed, so that a lens having a desired magnification can be produced. Accordingly, students can easily understand a structure of a phase microscope and the principles thereof, and a cell observed by using a digital camera or a mobile phone camera without using a special photographing device can be photographed and recorded as a picture or an image, thereby inspiring learner to have interests in science in educational institutes such as schools and the like. |
