What microscope is used to observe hair cuticles?
Hair cuticles are the building blocks of hair. Hair is mainly composed of epidermis, cortex, and medulla. The epidermis is made up of many overlapping tiny scales. This is what we call hair scales, which can be called a protective layer. When the hair scales are arranged neatly without gaps, they can refract external sunlight and make the hair appear shiny. If the hair cuticles become raised and the hair loses its protective layer, not only will the luster be lost, but deep damage will also be inevitable.
Since hair cuticles are so important, for daily chemical manufacturers who produce and develop shampoos and conditioners, observation and judgment of hair cuticles is an essential means for them to test their products.
Reflection optical microscopes and electron microscopes are commonly used for microscopic examination, but each has its own advantages and disadvantages. Optical microscopes result in unclear images due to illumination and depth of field problems. Electron microscopes are expensive and difficult for users to afford, and the surface of complex specimens is difficult to prepare. Damage, so we at Guangzhou Microfield Optical Instrument Co., Ltd. have tried to upgrade the hardware and shooting methods of optical microscope equipment to achieve shooting effects similar to those of electron microscopes.
What is the maximum magnification of an optical microscope?
By improving the performance of the lens, ordinary optical microscopes can achieve a magnification of about 1000-1500 times, but it has never exceeded 2000 times.
The maximum magnification of an electron microscope is more than 3 million times, while the maximum magnification of an optical microscope is about 2,000 times. Therefore, the atoms of certain heavy metals and the neatly arranged atomic lattice in the crystal can be directly observed through the electron microscope.
Optical microscopes include not only optical microscopes that can magnify more than a thousand times, but also electron microscopes that can magnify hundreds of thousands of times, allowing us to have a better understanding of the laws of life activities of organisms. Most of the experiments stipulated in the general middle school biology syllabus must be completed through a microscope. Therefore, the performance of the microscope is the key to doing good observation experiments.
