Purpose of various objective lenses:
4X: the imaging of insects, paper money, maintenance of electronic motherboard, etc. (you can see objects alone) is clearer than that of magnifying glass.
10x: look at the cell, look for the image, and preliminarily zoom in.
20x: look at mites, aquatic products, etc.
40x: look at cells, blood, sperm, eggs, artificial insemination, crude bacteria, etc.
100x: medical testing, blood testing, bacteria, scientific research, students' viewing of specimens, etc.
Q: what does oil mean?
A: the bullet means that the end of the objective lens is equipped with a bullet sheath. When observing, the object retracts and rebounds, which plays the role of protecting the specimen and the objective lens. Medium and high power objective lenses, such as 40 times (inclusive) and above multiple bands. The oil is 100x. When using the objective lens, immerse the lens in the oil for observation. The oil is cedar oil and special oil for microscope.
PDV has many different motorized linear translation stage including motorized translation stage, motorized linear stage, High Precision Motorized Goniometer Stages High Precision Motorized XY Stages, High quality China Motorized Linear Stage. They can be any combination, building block structure, can satisfy any scene usage requirement.
It is used for the fixation and adjustment of objective lens and lens.Meet the requirements of your experimental scenario.
