We have designed and built an optical system to collect light that is generated in the tunneling region of a low-temperature scanning tunneling microscope. The optical system consists of an in situ lens placed approximately 1.5 cm from the tunneling region and an ex situ optical lens system to analyze the emitted light, for instance, by directing the light into a spectrometer. As a demonstratio...

In this article results of a comparison of two NSOM probe characterization methods are presented. Scanning electron microscopy analysis combined with electromagnetic field modeling using the finite difference in time domain method are compared with measured far-field radiation diagrams of NSOM probes. It is shown that measurement of far-field radiation diagrams can be an efficient tool for dail...

Patterned illumination can be used to improve lateral resolution, provide optical sectioning, and to reduce illumination dose. For example, in Structured Illumination Microscopy (SIM), spatially periodic illumination patterns are used to double the resolution [1]. The use of a Spatial Light Modulator (SLM), such as a Digital Micro-mirror Device (DMD), gives full control over the illumination pa...

The purpose of the report is to describe the state of the optical microscope parts market in the Scandinavian countries, to present actual and retrospective information about the volumes, dynamics, structure and characteristics of production, imports, exports and consumption and to build a forecast for the market in the next five years. In addition, the report presents an elaborate analysis of ...

Quantitative microscopy has been extensively used in biomedical research and has provided significant insights into structure and dynamics at the cell and tissue level. The entire procedure of quantitative microscopy is comprised of specimen preparation, light absorption/reflection/emission from the specimen, microscope optical processing, optical/electrical conversion by a camera or detector, ...
