Which type of microscope is used to observe hair cuticles?
Hair scales are a component of hair. Hair is mainly composed of the epidermis, cortex, and medulla, and the epidermis is made up of many small overlapping scales, which are what we call hair scales. It can be called a protective layer. When the hair scales are neatly arranged without gaps, they can reflect the external sunlight and make the hair appear shiny. If the hair scales curl up and the hair loses its protective layer, not only will the luster disappear, but deep damage is also inevitable.
Since hair scales are so important, for daily chemical manufacturers who produce and develop shampoo and conditioner, observing and judging hair scales is an essential means for them to test their products.
The commonly used devices for microscopy are reflective optical microscopes and electron microscopes, but each has its own advantages and disadvantages. Optical microscopes have unclear images due to lighting and depth of field issues, while electron microscopes are expensive and difficult for users to afford. In addition, complex sample preparation can easily damage the surface of specimens. Therefore, Guangzhou Weiyu Optical Instrument Co., Ltd. has tried to upgrade the hardware and shooting methods of optical microscope equipment to achieve a shooting effect similar to that of electron microscopes.
The steps of using a microscope to make the object image clear
1. Mirror retrieval and placement
① Hold the mirror arm with your right hand and hold the mirror holder with your left hand
② Place the microscope on the experimental platform, slightly to the left. Install the eyepiece and objective lens
2. Regarding light
① Rotate the converter to align the low magnification objective lens with the through hole. Note that the front end of the objective lens should be kept 2 centimeters away from the stage
② Aim a larger aperture at the light hole. Look into the eyepiece with your left eye and open your right eye for future viewing and drawing. Rotate the mirror to see a bright field of view
