Focus XSP-100D: A microscopic exploration tool for coaxial coarse and fine focusing

In the teaching of biological experiments, the accurate observation of microscopic samples is the basis for acquiring accurate knowledge. From looking at the cell wall structure of onion epidermal cells to studying the budding and reproductive processes of yeasts, precise focus is crucial. The XSP-100D Student Teaching Monocular Biological Microscope's coaxial coarse and fine focus system is a great way to do this. It has a focal length adjustment range of up to 30mm and a focal length interval of just 0.002mm, which means that students will be able to adjust the focal length over a wide range while achieving extremely fine adjustments.

Taking the stomatal structure of plant leaves as an example, the stomata are an important channel for gas exchange between plants and the outside world, and their structures are small and complex. When using the XSP-100D, students quickly brought the objective close to the sample with coarse adjustments to roughly find the area where the leaf stomata are located. Due to the large coarse adjustment range, the observation distance can be quickly shortened and time can be saved. Subsequently, fine adjustments are made using micro-adjustments, and with a very small focal length interval of 0.002 mm, it is possible to clearly distinguish the guard cells and orifices of the stomata. This precise adjustment allows students to observe the opening and closing states of the stomata in different environments, so as to gain a deeper understanding of the physiological activities of plants.

Then look at the observation of animal cells, such as human oral epithelial cells. Oral epithelial cells are irregular and thin, requiring extremely high focus. With the XSP-100D Student Teaching Monocular Biological Microscope, students can easily visualize the cell membrane, cytoplasm, and nucleus of cells with coaxial coarse and fine focusing. The subtle structures such as chromatin in the nucleus can also be clearly identified, which is of great help to students in learning the basic structure and function of cells.

Ningbo Beilun Fangyuan Photoelectric Instrument Co., Ltd., with rich experience in the research and development of optical instruments, fully considered the actual needs of educational scenarios when designing the coaxial coarse fine focusing system of XSP-100D. After a lot of experiments and repeated optimizations, the technical team determined such adjustment parameters and structural design to ensure that the product reached the best level of observation accuracy.

The XSP-100D Student Teaching Monocular Biological Microscope has been introduced in some schools and educational institutions. Biology teachers reported that when students used the microscope for experiments, their observations improved significantly. In the past, when observing some subtle structures, students often had difficulty focusing clearly, resulting in poor experimental results. Now, with the XSP-100D's coaxial coarse microfocus system, students can easily capture clear images and gain a deeper understanding of the microscopic world of biology. The students also said that they were able to observe the details of the biological samples more accurately during the use process, which greatly stimulated their interest and desire to explore biological experiments.
