Comparison of domestic microscope and imported microscope
Generally speaking, domestic microscopes and imported microscopes have the following differences:
1, the price, the domestic microscope price is low, generally from a few thousand to tens of thousands of prices, more suitable for inspection requirements are not high, equipment and funds are limited to small and medium-sized enterprises. Imported microscopes are usually from tens of thousands to hundreds of thousands, due to different manufacturers and models of different price changes, mainly used in the inspection of higher requirements for the purchase of funds more abundant medium and large enterprises.
2, product quality, although domestic equipment is still developing and progressing, but the real product quality and technical aspects of product quality and imported foreign gap is still very large, I think in the short term is unable to catch up.
3, optical system: most of the domestic microscopes use a finite optical system, so the function of the product is relatively simple, some products use an infinite optical system, but the relevant technology is not very mature. Imported manufacturers use infinite optical system, of which the ICCS optical system of German Zeiss Company is the most advanced.
4, objective lens, the objective lens of domestic microscopes are mostly used achromatic objective lens, objective lens field of view is relatively small, the image contrast is relatively poor, the colour reproduction is not very good. Objective magnification up to 40 times, 100 times objective lens is mostly oil lens. Imported microscope manufacturers objective lens is divided into achromatic objective lens, semi-complex achromatic objective lens and complex achromatic objective lens, the latest objective lens technology for EC contrast-enhanced objective lens. The field of view of the objective lens is much larger than that of the domestic objective lens, and the imaging quality and contrast are excellent. The magnification of the objective lens can reach 100 times.
5, mechanical stability, the overall workmanship of domestic microscopes is relatively coarse super, mechanical failure is higher, especially after a few years of use, the overall performance of the equipment has declined significantly, the service life of 2-5 years (life and frequency of use and maintenance). Imported microscopes are more fine workmanship, mechanical stability, more than 5 years of service life.
