Light source of stereomicroscope

Stereomicroscope, also known as stereomicroscope, is the most commonly used optical microscope in metallographic microscope, polarizing microscope, biological microscope and fluorescence microscope. It has a long working distance, the magnification is generally 7x-45x, and the maximum is 180X. It is widely used in health, agriculture and forestry, public security, schools, scientific research departments for observation and analysis. It is also suitable for the inspection, assembly and repair of fine parts in electronic industry and instrument industry.

As we all know, the optical system is the most important part of the microscope, the quality of the optical system directly affects the imaging quality of the microscope. But as far as stereomicroscope is concerned, in addition to its optical system, its light source configuration is also very important, which has a great impact on the quality of digital imaging. As the friends of microscope purchasing group, we should pay attention to this point.

The light source of stereomicroscope generally includes cold light source and LED ring lamp. We can tell the supplier what the object you are observing and what effect you want to achieve, and ask the microscope supplier to recommend the light source that is most suitable for you.

Let me briefly introduce the h-150 optical fiber cold light source and LED ring lamp

1. H-150 optical fiber cold light source: H series optical fiber cold light source adopts switching power supply. The whole machine is small in size, light in weight and high in efficiency. It has the characteristics of stable output for a long time, so that the halogen lamp can work stably and its life can be increased. Taking slow start measures is conducive to protecting the halogen lamp and the power supply itself. In case of failure, the cold light source will automatically enter the protection state to prevent various safety problems.

With a filter, light with different color temperature can be easily obtained, and the color temperature of output light can be increased to 5600k.

High speed fan, reasonable air duct and heat insulation design are adopted to fully exhaust hot air in the engine, so that the external surface of cold light source is always in a relatively low temperature state.

2. LED ring lamp: led-305 LED ring lamp is a high brightness LED lamp specially designed for industrial stereo microscope, with adjustable brightness, low temperature, balanced, no flicker and no shadow. Exquisite metal shell insulation, anti-static, current control design to maintain a high degree of uniformity LED lighting, consistent color temperature, and good concentrating performance; unique embedded structure, users can add polarizer according to need, reduce light interference, thus significantly improving image quality. In addition, grinding glass can be selected to make the light soft.
