3) mirror lens 反射镜透镜4) Reflection lens 反射透镜5) X-ray compound lens X射线组合透镜 1. The X-ray compound lens is a novel refractive X-ray optical device. X射线组合透镜是一种利用折射效应对X射线聚焦成像的新型元件。 2. With the development and application of the x-ray compound...
1/F=1/f1+1/f2-d/f1f2 and p= p1+p2-dp1p2 When one surface of the lens is silvered, the lens forms a mirror. Thereby, the focal length of the formed silver lens is given by: 1/F= 2/f1+1/fm where f1= focal length of lens where refraction is produced and fm= focal length ...
The combination of a tunable acoustic gradient (TAG) lens and a resonant mirror were integrated into a multiphoton excited (MPE) microscope that is rapidly and precisely controlled by an embedded field programmable gate array (FPGA) to acquire images at high frame rate.Chia-Wei ...

Accommodation in humans is performed by ciliary muscle and iris sphincter contractions, convergence and changes in the shape and position of the lens. The latter action is passive, meaning the lens changes are dependent on the ciliary muscle and iris contractions. Also, when the centre of the ...
A lens of focal length {eq}10 \ cm {/eq} is placed in contact with a lens of focal length {eq}-15 \ cm {/eq}. What is the focal length of the combination? Focal Length: It is defined as the measure of how efficiently a ...
A concave mirror of focal length f1 is placed at a distance of d from a convex lens of focal length f2. A beam of light coming from infinity and falling on this convex lens concave mirror combination returns to infinity. The distance d must equal View Solution Q2 An object is placed ...
The link I gave earlier (repeated__HERE__) gives the following formula for determining the maximum useful field: Longest useful eyepiece focal length = telescope f-ratio x maximum exit-pupil diameter Thus, if you want a maximum pupil of 6.5mm and given your f/1.8 lens you'd want a focal...
