(显微镜或望远镜的)目镜 The eyepiece of a microscope or telescope is the piece of glass at one end, where you put your eye in order to look through the instrument.
There is more to sharpness than merely the center of the field, however, and it is the resolution of the outer perimeter of the fields of view that really set apart the superb eyepieces from the good. 顶级的目镜不仅中心锐利,边缘也很锐利,这也是区分顶级与较好目镜的一个标准。
Eyepieces can be found with shorter eye reliefs than that, but they are not comfortable to use for long periods. 目镜中有不少是小于8MM焦距的,但是长时间的观测会非常的不舒服。
Water won't hurt these binoculars, but raindrops on your eyepieces will definitely spoil your view. 虽然雨水不能损坏这具望远镜,但落在目镜上的雨滴会令望远镜中的景物模糊。
The ocular micrometer is calibrated for the microscope ( s) in which it is used and it is recalibrated each time the eyepieces or objectives are changed. 显微镜上的微尺是否进行校准,并且在每次更换目镜或物镜时重新校准?
Design of Hybrid Refractive-Diffractive Ultra-Wide-Angle Eyepieces 折-衍混合超广角视场目镜系统的设计
The optical performance of the hybrid eyepieces are studied and compared with the Kellner eyepiece. 设计结果与传统凯涅尔目镜的光学性能进行了分析和比较。
Basing on conventional 4 elements 70 ° field of view wide angle Zeiss eyepiece, we have designed two hybrid refractive diffractive eyepieces by replacing the doublet of the eyepiece with hybrid refractive diffractive singlet. 以传统4片70°视场蔡司目镜为基础,用折/衍混杂单透镜代替系统中的双胶合透镜,给出了衍射面分别位于单透镜两面不同位置时的折/衍混杂目镜系统。
The designing considerations and procedure of hybrid refractive diffractive ultra wide angle ( 70 °) eyepieces are presented, one is with two diffractive surfaces and another is with single diffractive surface. 在传统的超广角(70°)赛得莫尔(Scidmore)目镜的基础上,设计了两个折衍混合70°视场的目镜。
Most modern metallurgical microscopes adopted the so-called infinity optical system design, in addition, plano-achromatic objectives, wide-field eyepieces, and high magnification dry objectives are widely used. 现代金相显微镜已普遍采用无限远光学系统设计,并广泛使用平场消色差物镜、广视场目镜、高倍干物镜;
