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…
Video Tutorial: How to Align the Bulb of a Fluorescence Lamp Housing
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…
How to Clean Microscope Optics
Clean microscope optics are essential for obtaining good microscope images. If they are dirty, the microscope should be cleaned to avoid a loss of quality. If you decide to do this yourself, you…
Optical Microscopes – Some Basics
The optical microscope has been a standard tool in life science as well as material science for more than one and a half centuries now. To use this tool economically and effectively, it helps a lot to…
Basic Principles of Luminescence
There are a lot of light-emitting processes occurring in nature. Luminescence is an umbrella term for those kinds of events where light emission is not the result of high temperatures. This article…
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…
Integrated Modulation Contrast (IMC)
Hoffman modulation contrast has established itself as a standard for the observation of unstained, low-contrast biological specimens. The integration of the modulator in the beam path of themodern…
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…
Depth of Field in Microscopy
In microscopy, depth of field is often seen as an empirical parameter. In practice it is determined by the correlation between numerical aperture, resolution and magnification. For the best possible…
