Infinity Optical Systems

“Infinity Optics” refers to the concept of a beam path with parallel rays between the objective and the tube lens of a microscope. Flat optical components can be brought into this “Infinity Space”…

Imaging of Host Cell-bacteria Interactions using Correlative Microscopy under Cryo-conditions

Pathogenic bacteria have developed intriguing strategies to establish and promote infections in their respective hosts. Most bacterial pathogens initiate infectious diseases by adhering to host cells…

Life Science Imaging with DVM6 Digital Microscope

Digital microscopes can be a great help in life science applications such as the documentation in botany, entomology studies and crop science, or the digitization of museum collections. The image…

Cataract Surgery with CoAx4 Illumination

A stable red reflex is one of the most important features of an ophthalmic surgical microscope for cataract surgery. It’s the red reflex that makes the structure of the lens visible and thus makes for…

Workflows & Protocols: How to Isolate Individual Chromosomes with Laser Microdissection

During the first Leica Workshop in Brazil, at the Centro de Energia Nuclear na Agricultura/USP (CENA), the participants learned how to prepare samples for laser microdissection (LMD) using a cryotome.…

A Brief History of Light Microscopy

The history of microscopy begins in the Middle Ages. As far back as the 11th century, plano-convex lenses made of polished beryl were used in the Arab world as reading stones to magnify manuscripts.…

Vom Licht zur Erleuchtung: Sensoren und Messverfahren in der konfokalen Mikroskopie

In diesem Beitrag werden die wichtigsten Sensoren kurz vorgestellt, die in der konfokalen Mikroskopie verwendet werden. Mit konfokaler Mikroskopie ist hier „True Confo-cal Scanning“ gemeint, also das…

Video: The White Light Laser – How to Effectively Excite Multiple Fluorophores with a Single Light Source

The Leica White Light Laser produces a continuous spectral output between the wavelengths of 470 and 670 nm. It allows you to select 8 excitation lines from 3 trillion unique combinations for…

Workflows & Protocols: How to Use a Leica Laser Microdissection System and Qiagen Kits for Successful RNA Analysis

Laser Microdissection (LMD) allows isolating individual cells or chromosomes and is a well established technique for sample preparation prior downstream analysis of the nucleic acid content via PCR or…
