The most commonly used UV microscopy and polarization microscopy
UV microscope is a necessary component of the lens, its main role is to prevent ultraviolet light-sensitive material to reduce transmission to the blue-violet light, so that a clear vision to improve the contrast of distant scenery and color saturation . However, now with the DSLR CCD and CMOS for use as film to UV is not as sensitive, but we recommend installing a high UV transmittance of the lens to protect the lens to avoid lens contamination or damage. For entry in terms of players, I recommend Ken multilayer coated high or corn UV, cheaper than double-coated UV, multi-layer coating has a higher UV transmittance, and the price is not very expensive. With a 62mm,
coach shoes, UV, for example, general multi-coated UV Kenko price of 80 yuan, corn multi-coated UV (HMC) is priced at 90 yuan, while the double-coated UV Kenko price of only 40. Of course, higher prices,
Sell potato - Chongqing, then the classic FLASH -, better performance of the UV there are many, but considering the quality of entry-level optical lens is generally not very high, so a piece of expensive B + W really does not make sense. Intermediate players can take into account the high and the corn is willing to high-end products, or B + W's in the low-end products. And speaking of small burn-class players, B + W's top products can try out, the original UV is also a good choice,

role of polarizer is to eliminate harmful reflected light, such as water or glass from the light reflected from shiny surfaces, improve image clarity and expression, to increase color saturation, such as it can make the blue sky, green leaves,

coach outlet, so here is relatively inexpensive recommended Hoya polarizer. Can be considered in order for players to consider multi-layer coating Kenko polarizer, or B + W slim PL-C. For the small burn-class players to direct on the B + W,
