WDK 干涉測量鏡頭
適合非接觸光學壓型
可選Michelson (2x and 5x) 鏡頭
F=200mm鏡筒遠場校正設計
用途:
干涉測量鏡頭可用在非接觸光學壓型測量設備上,通過此鏡頭可得到表面位圖和表面測量參數等。也可用來檢測表面粗糙度,測量精度非常高,在一個波長之內。一束光通過分光鏡,可將光直接射向樣品表面和內置反光鏡。從樣品表面反射的光線通過再結合,就產生了干涉圖案。Michelson鏡頭擁有更長的工作距離,更寬的視場和更大的焦深。采用F=200mm鏡筒的話可將鏡頭直接裝配到C接口相機上。
WDK Interferometry Objectives
Suitable for Non-Contact Optical Profiling
Michelson (2x and 5x)
Infinity Corrected F=200mm Tube Lens Design
Interferometry objectives are used in non-contact optical profile measurement devices to obtain surface maps and surface measurement parameters. They can be used to examine surface topography with very high precision—to within a fraction of the wavelength of light. In these objectives, a light beam passes through a beamsplitter, which directs the light to both the surface of the sample and a built-in reference mirror. The light reflected from these surfaces recombines and a fringe interference pattern is formed. The Michelson objectives provide comparatively longer working distances, wider fields of view and larger depth of focus, whereas the the F=200mm tube lens allows these objectives to be integrated to a C-Mount camera.
