观察标本时,必须依次用低、中、高倍镜,最后用油镜。当目视接目镜时,特别在使用油镜时,切不可使用粗调节器,以免压碎玻片或损伤镜面。如果不出现物象或者目标不理想要重找,在加油区之外重找时应按:低倍→高倍→油镜程序。在加油区内重找应按:低倍→油镜程序,不得经高倍镜,以免油沾污镜头。
使用后镜头的清洁:镜面只能用擦镜纸擦,不能用手指或粗布,以保证光洁度,用完油镜必须进行“三擦”(观察完毕,上悬镜筒,先用擦镜纸擦去镜头上的油,然后再用擦镜纸沾取少量乙醇乙醚溶液擦去残留的油,最后用擦镜纸擦去残留的乙醇乙醚溶液,后将镜体全部复原)。
用油镜观察时应注意哪些问题?
油镜是一种将光线反射而成的映像放大的仪器,能够用于观察远距离的景物以及交通工具的盲区。在使用油镜观察时,需要注意以下问题:
1. 选择合适的油镜
油镜材质和放大倍数不同,观察效果差异很大。因此,在购买油镜时,需要选择适合自己需求的材质和倍数的油镜,否则会影响观察的效果。
2. 保持油镜清洁
油镜被灰尘和污渍覆盖会极大影响观察效果,因此,要经常清洗和擦拭油镜镜面,以保持油镜镜面的干净。
3. 观察时要关注安全
在使用油镜观察外界环境时,要注意安全,不要过于依赖于油镜,而忽略周围环境。
4. 注意观察视角
观察时,要注意油镜和观察对象之间的距离和角度,尤其是在观察高速行驶的交通工具时,不要因为视角问题,导致误判。
【英文介绍/For English】:
When observing the specimen, the low, medium and high magnification must be used in sequence, and the oil lens must be used last. When viewing the eyepiece, especially when using the oil lens, the coarse adjuster must not be used to avoid crushing the glass slide or damaging the mirror surface. If there is no object image or the target is not ideal and you need to search again, you should press the procedure of low magnification → high magnification → oil mirror when searching outside the refueling area. In the refueling area, you should follow the procedure of low magnification → oil mirror, and do not go through a high magnification mirror to avoid oil contaminating the lens.
Cleaning of the lens after use: the mirror surface can only be wiped with lens tissue, not fingers or coarse cloth to ensure the smoothness. After the oil lens is used up, "three wipes" must be carried out (after observation, the lens barrel is hung up, first wiped with lens tissue Remove the oil from the lens, and then use a lens tissue to dip a small amount of ethyl ether solution to wipe off the remaining oil, and finally use the lens tissue to wipe off the remaining ethyl ether solution, and then restore the entire lens body).
