Microscope was discovered during the time of Anton van Leeuwenhoek who lived sometime in the years, 1632 to 1723. Being an employee of a store selling fabrics, he was tasked in counting the fibers or threads that where to be sold. Working with lenses, part of his job was the polishing of lenses to make the objects clearer or increasing the magnifications of the lenses when properly polished. By doing so, he was able to see objects or fibers 270 times the apparent size to the naked eye. With this newly discovered ability, he applied the instrument in the study of insects, bacteria, yeast cells, and many organisms found in ponds of water and even in the circulation of blood cells in capillaries. His discovery of the microscope laid the foundation of all types of microscopes that followed several centuries after. Noteworthy to mention here are the compound microscopes, electron microscopes, and even digital microscope. In our modern world, innovations and modifications are done to satisfy the different needs of people working in different fields of endeavors- scientists, doctors of different specialties, engineers and especially people working at NASA. Children, with their appetite of curiosity, must be given access to things that would provide them with knowledge, wonders, and appreciation of nature.

It may even lay down the foundation of scientific interest in the future. Who knows, some of them may become scientific leaders in our community. However, along the line of a simple microscope, comes this convenient, cheaper microscope ideal for children designed to give access towards the study of minute things that we barely see with our naked eyes. Comes now the Blister microscope, very affordable and offers a magnitude of opportunities through its design. Some of its features are: it offers top light which affords exceptional viewing of objects in three dimensional views; the filter and mirror system conducts light and sub stage using single bulb for reflected and transmitted light viewing. The definition is considerably improved because the filter location is more distant from object; even without electricity viewing is still possible by a window or outdoors in daylight, for dark field viewing one has only to cover the filter; the base and the yoke are made of metal aluminum, anodized aluminum stage, tube, light shield, and lens cells; standard thread objective; uses standard lamp- 6 watt lamp. This is a low powered microscope. Here is a testimonial from a customer who found the Blister Microscope to be a great value) I have used your Blister Microscopes in my 6th and 7th grade science classrooms for eight years. I have nothing but praise for your products. Now, I would like to get one for my personal use. Please advise me as to the costs, models available, etc. I have been using Sr. model 68-50x GSS Blister Viewer Microscope in class. However, this is for my husband who is an extension agent. It will be used for a variety of specimens, including coins.
