A high power objective lens is a microscope lens with a high magnification level, used for viewing specimens in fine detail. It allows for closer inspection of specific features or structures of the specimen.
Storing a microscope with the low power objective lens in place helps protect the lens and prevents accidental damage or contamination during storage. The low power lens is less delicate compared to other high-power lenses, making it a safer option for storage to ensure the microscope remains in good condition for future use.
When focusing an image under high power, you should use the fine focus knob. This allows for precise adjustments and helps avoid damaging the slide or the objective lens. Additionally, start with the lowest power objective lens to locate the specimen before switching to high power for detailed observation. Always ensure the stage is lowered before switching to high power to prevent contact between the lens and the slide.
Start with the lowest magnification objective lens, typically 4x or 5x, as it provides a wider field of view and makes it easier to locate the specimen.
You typically start with the low-power objective lens and the coarse focus knob when focusing your microscope. This allows you to bring the specimen into view quickly and then fine-tune the focus using the high-power objective lens and the fine focus knob.
Because you are at the highest magnification, only turn the fine adjustment knob when you are using the high-powered objective lens, and not the coarse adjustment. Otherwise you risk getting your sample out of focus, and you will probably only be able to refocusby starting with the lowest power objective lens.
The revolving nosepiece or turret rotates to change from the low power objective lens to the high power objective lens on a microscope. This component allows for easy switching between different objective lenses without the need to manually remove and insert them.
So you do not crack the high power objective lens - this lens is very fragile and expensive.
The nosepiece of a microscope holds multiple objective lenses, each with different magnification levels that range from high to low power. Rotating the nosepiece allows you to switch between these objective lenses to adjust the magnification of your specimen.
A high power objective in a microscope is a lens that provides high magnification of the specimen being viewed. It typically magnifies the image by 40x to 100x, allowing for detailed observation of fine structures. High power objectives are used for examining smaller details and are typically used after lower magnification objectives.

The smallest objective on a microscope is called the high-power objective lens. It typically has a magnification power of 40x or higher, allowing for detailed examination of specimens.
The oil immersion lens or objective has power 90X-100X and an eyepiece lens generally in light microscope comes with 10X so total magnification of oil immersion lens is 100X10 = 1,000

You can estimate the size of the object by comparing the field diameters observed under the low power objective lens (4x) and high power objective lens (40x). Calculate the ratio of the field diameters (40x/4x = 10), and use this ratio to estimate the size of the object viewed under the high power objective lens. Simply multiply the size of the object viewed under the low power objective lens by the ratio (field diameter at 4x) to get an estimation.
