Microscope is a Optical instrument composed of one lens or a combination of several lenses. It is one of the great inventions of mankind. Before it came out, our ideas about the world around us were limited to seeing with the naked eye, or relying on handheld lenses to help the naked eye see things. However, the emergence of microscopes brought a whole new world to our view, and people saw hundreds of them for the first time; New” The internal structure of tiny animals and plants, as well as various things from the human body to plant fibers, is truly amazing!


Microscopes are classified according to microscopic principles, and can be roughly divided into polarizing microscope, optical microscope, electron microscope, Digital microscope, etc. There are many brands of microscopes on the market, but whether they are domestic or imported, there is one brand that everyone knows, which is Leica, a global leader in microscopes and scientific instruments with a history of 160 years. Leica Microscope has always focused on product research and development and the application of new technologies, and ensures that the quality of its products has always been at the forefront of the microscope manufacturing industry, So today, the editor is going to talk about this semi-automatic professional polarizing microscope Leica DM4 P from Leica.

   Leica DM4 P is a research level semi-automatic intelligent digital professional upright polarizing microscope with a simple structure and flexible operation. The objective turntable is equipped with 6 objectives and has different magnifications, which can obtain rich sample information. For studying crystal structure, a polarizing microscope is a better choice. Whether it's minerals, plastics, polymers, drugs, pharmaceuticals, fuels, or binders, this Leica microscope can make samples appear crystal clear and transparent, helping you observe interesting content and complete your research or quality control tasks. It can be said that comprehensive services are readily available. Please take a look at the detailed performance and usage introduction below.


1： By encoding components to store and call up information, when changing the objective lens, the lighting intensity and aperture settings can be called up through the lighting intensity control and contrast manager. Mainly thanks to the existence of the encoding objective turntable, the captured images are always calibrated.


2： Identify the structures of interest, with a 25-mm wide field of view providing you with a perfect overview image. What can show you the specific information you need is often the overall image at low magnification, rather than the detailed image, such as flow structure, deformation structure, or strip arrangement structure caused by cooling process.

    3： The objective turntable is equipped with 6 objective lenses with different magnifications, helping to obtain rich sample information. This Leica microscope uses a 2.5x overview objective lens to identify the macroscopic structure in the sample. If you want to use cone light method to conduct detailed research on optical properties, you can switch to 63x magnification, and switch to 100x to detect reactions along particle boundaries. The objective turntable is also encoded, providing you with intelligent support.

    4： The Leica DM4 P polarizing microscope can be configured to use transmitted or incident light for LED lighting, or to use two light sources at once. When measuring reflectivity, incident light must be used, such as observing ore or coal. When conducting birefringence measurements, transmitted light is required, such as for detecting geological thin films, polymer films, or drugs. We know that in special applications such as geological research, both types of light are essential. When the microscope is configured to use both incident and transmitted light, the relevant objective (with or without cover glass correction function) should be used starting from a magnification of>10 times.

    5： Leica DM4 P is very suitable for cone method, and a stress free objective with high magnification and high numerical aperture is a necessary condition for this application. The use of a special 63x Leica objective lens can meet the higher requirements of polarization level 5, thus obtaining better results.

    The above is the usage guide for Leica DM4 P, a Leica microscope. Please check it. If you have any questions about other microscopes, Chain Metallography welcomes you to inquire!
