1. Excellent Image Quality<\/strong>
\nNIS optical system and optical elements using advanced coating technology make it easy to obtain good quality imaging. Excellent optical system is the guarantee of obtaining plan and clear images. Infinite achromatic semi-pan objective and even plan objective can be used in this microscope. It can provide clear images with high contrast, and the clear range can reach to the edge of the field of view. It also has bright and uniform illumination.
\n2. BS-2054 has color temperature adjustable function<\/strong>
\nBS-2054 has color temperature adjustable function, the color temperature can be adjusted to makes the sample present natural color. Its color temperature changes according to observation needs, even if the user changes the brightness, it can maintain the brightness and color temperature comfortably. The LED design life is 60,000 hours, which not only reduces maintenance costs, but also stabilizes the brightness during the whole service life.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

5. Applicable to Any Environment<\/strong>
\nAnti-mold treatment greatly extends the service life of the microscope. Since the objective, eyepiece and observation tube are all effectively anti-mildew treated, they can ensure continuous clear image and prolong the service life of the microscope. Even working in hot and high humid environment is not affected the working life.

6. Easy to Store and Transport<\/strong>
\nBS-2053, BS2054 series microscopes are small enough to fit into a common classroom cabinet. There is a special carrying handle at the back, and it has light weight, good stability and stable structure. The back panel of the microscope is designed with a hub device, which can effectively store the long power cord, improve the cleanliness of the laboratory, and also reduce the trip accidents caused by the long power cord during transportation. Wooden storage box as an optional accessory can bring great convenience for storage and handling.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
