The objective lens
Don't crush the slide with the objective lens.
remove the slide,return the low-power objective, use lens paper to clean the stage of microscope and the lenses
Refers to the type of microscope Leeuwenhoek created with one single lens. Small glass or plastic piece that is used to cover a water drop on a slide is a coverslip.
To focus a microscope from 4x to 40x, start by using the 4x objective lens. Position the slide on the stage and use the coarse focus knob to bring the specimen into view, adjusting the light as needed. Once focused, switch to the 10x objective lens, using the fine focus knob to sharpen the image. Finally, switch to the 40x lens, again using the fine focus knob for optimal clarity, ensuring not to use the coarse knob at this magnification to prevent damage to the slide or lens.
When removing or placing a new slide on the stage of a microscope at 4x, 10x, or 40x magnification, the objective should be set to the lowest power (usually 4x) to ensure proper clearance and avoid damaging the slide or the objective lens. This allows for easier positioning of the slide and prevents potential collisions between the slide and the lens. Once the slide is securely in place, you can then switch to a higher magnification for detailed observation.
The upper lens in a microscope is called the eyepiece or ocular lens. It is the lens through which the viewer looks to observe the magnified specimen on the microscope slide.
The part of the microscope that you put under the slide is called the objective lens. This lens is responsible for magnifying the specimen on the slide for viewing.
It's called an "OCULAR" according to a microscope supplier site.
The flat surface of a microscope that holds the slide for viewing is called the stage. It is where the specimen slide is placed for examination under the microscope's lens.
The objective lens
The part that holds the slide in place on a microscope is called the stage. The stage is where you place your sample slide for viewing under the lens of the microscope.
On a microscope with the usual 3-lens turret it is usual to use the objective lens with the lowest magnification to first examine your specimen. This gives a wider overall view of the subject, and will allow you to choose the particular detail that best suits your study. You may then move on to a higher magnification, if necessary, to study finer detail. If you started with the highest magnification, your fine focus will be uncertain, and you risk the front of the objective lens coming into contact with the sample slide. This could damage your specimen, and may damage the front of the lens.
The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.
The part of the microscope is called the stage. It is located under the objective lens and holds the stage clips.
The 'object lens' in a compound microscope is closest to the object being examined.
The platform on which you place the slide on a microscope is called the stage. It is where the slide is positioned for viewing and can be moved horizontally and vertically to adjust the position of the specimen under the objective lens.
