Epi-Illumination Fluorescence and Reflection-Contrast Microscopy
This article discusses the development of epi-illumination and reflection contrast for fluorescence microscopy concerning life-science applications. Much was done by the Ploem research group…
Differential Interference Contrast (DIC) Microscopy
This article demonstrates how differential interference contrast (DIC) can be actually better than brightfield illumination when using microscopy to image unstained biological specimens.
Phase Contrast and Microscopy
This article explains phase contrast, an optical microscopy technique, which reveals fine details of unstained, transparent specimens that are difficult to see with common brightfield illumination.
Immersion Objectives
How an immersion objective, which has a liquid medium between it and the specimen being observed, helps increase the numerical aperture and microscope resolution is explained in this article.
Mechanically Stressed Cells under the Microscope
Traumatic brain injury, skin scarring, or fibrotic heart remodeling are examples for mechanical stress which cells and tissues are exposed to. In this article, the authors introduce a non-invasive,…
Hydraulics in the Automotive and Aerospace Industries
Cleanliness standards relating to lubricants, hydraulic fluids, and oils, e.g., ISO 4406 and DIN 51455 are discussed in this article. Cleanliness plays a central role in the automotive and…
Studying Pulmonary Fibrosis
The results shown in this article demonstrate that fibrotic and non-fibrotic regions of collagen present in mouse lung tissue can be distinguished better with polarized light compared to brightfield.…
Factors to Consider When Selecting a Research Microscope
An optical microscope is often one of the central devices in a life-science research lab. It can be used for various applications which shed light on many scientific questions. Thereby the…
The Fundamentals and History of Fluorescence and Quantum Dots

The traditional light source for fluorescence excitation is a fluorescence lamp housing with mercury burner. A prerequisite for achieving bright and homogeneous excitation is the correct centering and…
Video Tutorial: How to Change the Bulb of a Fluorescence Lamp Housing
When applying fluorescence microscopy in biological applications, a lamp housing with mercury burner is the most common light source. This video tutorial shows how to change the bulb of a traditional…
Fluorescent Proteins - From the Beginnings to the Nobel Prize
Fluorescent proteins are the fundament of recent fluorescence microscopy and its modern applications. Their discovery and consequent development was one of the most exciting innovations for life…
Optical Contrast Methods
Optical contrast methods give the potential to easily examine living and colorless specimens. Different microscopic techniques aim to change phase shifts caused by the interaction of light with the…
Polarization Contrast
Polarization microscopy is routinely applied in material sciences and geology to identify minerals on the basis of characteristic refraction properties and colors. In biology, polarization microscopy…
Fluorescence in Microscopy
Fluorescence microscopy is a special form of light microscopy. It uses the ability of fluorochromes to emit light after being excited with light of a certain wavelength. Proteins of interest can be…
Forensic Detection of Sperm from Sexual Assault Evidence
The impact of modern scientific methods on the analysis of crime scene evidence has dramatically changed many forensic sub-specialties. Arguably one of the most dramatic examples is the impact of…

기본 현미경 기술
기본 현미경 기술은 현미경 스테이지의 전체 표본이 광원에 노출되는 경우에 사용됩니다. 전체 시편은 위(거꾸로 구성) 또는 아래(표준 정립 현미경)에서 백색광으로 조명됩니다. 시료의 투명도와 대상 또는 관심 영역에 따라 관심 있는 복잡한 세포 구조를 구별하기 위해 다양한 형광 입자가 사용됩니다.
DIC 현미경
DIC 현미경은 광원과 콘덴서 렌즈 사이, 대물렌즈와 카메라 센서 또는 접안렌즈 사이에 편광 필터와 Wollaston 프리즘이 있는 광학 현미경입니다.
암시야 현미경
암시야 대비법은 재료 시료의 불균일한 특징부 또는 생물학적 표본의 구조로부터 광의 회절 또는 산란을 이용합니다.
