A solid immersion lens (SIL) has higher magnification and higher numerical aperture than common lenses by filling the object space with a high-refractive-index solid material. SIL was originally developed for enhancing the spatial resolution of …

Immersion lithography is a technique used in semiconductor manufacturing to enhance the resolution and accuracy of the lithographic process. It involves using a liquid medium, typically water, between the lens and the wafer during exposure.

在这篇文章中，我们将简要地看一下如何在盖玻片和物镜前透镜之间利用浸泡介质帮助提高NA和分辨率。 此外，我们还将考虑空气和构成载玻片、盖玻片的玻璃的折射率，以及当光从一种介质传播到另一种介质时，如何使用浸没介质部分地减少错配。 此外，文中还提供了使用油浸式物镜的实用技巧以及水浸式物镜的优势，特别是针对活细胞的成像。 光学显微镜所面临的主要问题之一是克服某些光学分辨率的限制并提高系统的NA值。 简言之，物镜的NA是指从标本中收集光的能力， …

2022年6月27日 · Immersion optics enable creation of systems with improved optical concentration and coupling by taking advantage of the fact that the luminance of light is proportional to the square of...

2016年8月12日 · Because of its optical transparency, high refractive index, and deep-subwavelength structures, this 3D all-dielectric metamaterial-based solid immersion lens (mSIL) can produce a sharp image with a super-resolution of at least 45 nm under a white-light optical microscope, significantly exceeding the classical diffraction limit and previous near ...

A submillimeter solid immersion lens (SIL) is a high-index material lens designed to observe electromagnetic radiation in a specific frequency band. The lens has a unique spherical upper surface and a flat bottom surface for receiving objects. Solid immersion lenses (SIL) are commonly used in optical systems that require high-resolution imaging.

2023年4月27日 · Here, solid immersion lenses are demonstrated in silicon carbide using a fabrication protocol combining grayscale lithography and hard-mask techniques to allow nearly hemispherical lenses of 5 μ m radius to be etched into the substrate.

In this study, the advantages of laser-written NV – centers are combined with back-end integration of GaN solid immersion lenses using an additive micro-assembly method, avoiding any damage to the host crystal. This heterogeneous integration approach allows the decoupling of the lens fabrication processing from the vacancy center definition ...

Immersion lenses are optical elements that improve the detectivity of an infrared detector . The lenses used at VIGO Photonics generate no losses, require no alignment and offer maximum efficiency immediately after they are manufactured. The immersion may limit the angle of view of a detector (this applies to hyperhemispherical immersion lenses)

Besides high spatial resolution, solid immersion microscopy also possesses all the good properties of far-field imaging, such as high transmission efficiency and parallel imaging capability, which make it outstanding among beyond-the-diffraction-limit optical imaging techniques.
