查询词典 concave lens

Of course using such film means ISO speeds of under 100, which means that a tripod, cable release and mirror lock-up are a necessity when combined with the use of the lens' optimum aperture.

当使用最佳光圈时，你还应该同时使用ISO100或者更低速的胶卷（如ISO50的 FUJI VELVIA －译者注），相机的反光板锁定功能，三角架，以及快门线。

A 65mm FL910mm f/14 doublet achromatic lens was used.

甲65毫米双FL910mm f/14用消色差透镜。

Element achromatic lens with adjustable screw for collimation.

2元消色差透镜可调螺丝直。

of designing an achromatic lens with F/#=1 and aperture D=5mm is developed and numerical simulation is performed.

利用这种特性，本文提出了一种变深度亚波长孔阵金属折衍混合透镜（DV- SHAM R/D lens），它是由DV- SHAM lens与折射透镜结合，能够消色差，实现宽波段成像。

We use Welford's aberration equation to obtain the initial phase parameters of the diffractive surface of the designed hybrid achromatic lens.

复合透镜不同於传统折射透镜，它一面为传统折射透镜，另一面为绕射透镜；它不但可消色差及降低其他像差，在体积及重量的缩小上也有相当的成效。

Radiation from a fiber coupled diode (core diameter 0.4 mm, N.A. 0.3) is coupled into Tm5% at.,Ho(0.5% at.∶GdVO4 crystal by a pair of achromatic lens for end pumping. Output power of 3.6 W at 2.048 μm is obtained under pump power of 14 W and emission wavelength of 794 nm. The optical-optical conversion efficiency is 25.7% and slope efficiency is 26.6%.

在液氮制冷晶体条件下，利用光纤耦合激光二极管及消色差光学耦合系统端面泵浦双掺5％Tm，0.5％Ho∶GdVO4晶体，在泵浦功率14 W、泵浦波长794 nm时，实现了2.048 μm激光输出，连续运转输出功率3.6 W，相应的光光转换效率为25.7％，斜率效率26.6%。

Featuring wider angle views than predecessors, a new "super achromatic" objective lens,"Phase Corrected" Abbe-Koenig prisms, light transmission of at least 91%, and nitrogen filled composite housings reinforced with fiberglass to assure high endurance. In September 1994 Zeiss announced the first "Contax" 35mm rangefinder camera with interchangeable lenses made since 1959; the "G1" features include auto focus with any of four optional lenses, TTL metering, automatic film advance of up to 2 frames per second, and a luxurious titanium body.

这些新品体现了公司技术成就的最新进展，拥有较以前产品更宽的视角，新型&超消色差&物镜，&相位修正&阿贝-科宁棱镜，至少91%的透光率，充氮加固玻璃纤维复合镜室，以确保产品的耐用性。1994年9月，蔡司又推出了自1959年以来的首款镜头可互换型&康泰克斯&35mm连动测距对焦相机；此款&G1&型相机包括自动对焦功能和可任选的四个镜头，晶体管逻辑电路测距（TTL，晶体管逻辑电路），每秒高达两帧的自动卷片功能，和豪华钛机身外壳。
