Large numerical aperture scattered light condenser lens matched with electrooptical multiplier tube large photosensitive surfaceThe invented scattered light condenser is made up by using first plano-convex lens and second plano-convex lens and fixing them in a sleeve, and the convex surfaces of said ...
When using an objective lens with a numerical aperture of 0.40 or more, a condenser must be provided. The condenser lens can not only make up for the lack of light quantity and properly change the properties of the light from the light source, but also focus the ligh...

When using an objective lens with a numerical aperture of 0.40 or more, a condenser must be provided. The condenser lens can not only make up for the lack of light quantity and properly change the properties of the light from the light source, but also fo...
The design of a condenser becomes more complex with increasing aperture. For numerical apertures up to 0.1 a single lens is used; for apertures of 0.2–0.3, a two-lens condenser; for apertures greater than 0.3, a three-lens condenser. The most common type of condenser consists of two identi...
The Abbe condenser is a fundamental type of microscope condenser known for its simple and effective design. Typically consisting of a lens system, the Abbe condenser is positioned below the microscope stage. It often incorporates an iris diaphragm for controlling the aperture size and allows users ...
(the one with highest magnification) must have a drop of oil placed at its tip. This forms a continuous medium to transmit a beam of light from the condenser to the objective lens and effectively increase the numerical aperture. 要最大化明亮领域显微镜的分辨能力,油浸没透镜 (那个以最高的放大...
1, has a numerical aperture of approximately 0.90, excellent correction for spherical aberration, coma and pupillary aberration. Referring to FIG. 1, a biconvex positive singlet I and a convex-plano positive singlet II are axially aligned. The pupil plane of the condenser system is external to...
The article focuses on designing of Fresnel zone plate optics for photon energies and demonstrates X-ray holography limited by the numerical aperture of pr... JA Soltau - Göttingen Series in X-Ray Physics 被引量: 0发表: 2022年 Transmission X-ray microscopy for full-field nano imaging of ...
minimize exposure times. In addition to these optical metrics, there are also those of the scalability to higher numerical aperture (NA) imaging systems, and the ease of manufacturability of the condenser. Present, known condenser designs have proven unable to meet all of the requirements demanded...
