Comparison between domestic microscope and import microscope
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 limited funds for 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 prices vary greatly, 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 using a limited optical system, so the function of the product are relatively simple, some ** products using an infinite optical system, but the relevant technology is not very mature. Imported manufacturers use infinite optical system, of which the German Zeiss company's ICCS optical system * is 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 lens magnification * high can reach 40 times, 100 times the objective lens more oil lens-based. Imported microscope manufacturers objective lens is divided into achromatic objective lens, semi-complex achromatic objective lens and complex achromatic objective lens, * the new objective lens technology for the 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.
