Fluorescence microscopy image on the left with no distinction between the fluorescent signal and background autofluorescence. FLIM was used in the image on the right to differentiate autofluorescence in chloroplasts (blue) from the desired fluorescent signal from the cell membrane (green).

Learn how to Remove Autofluorescence from your Confocal Images

Autofluorescence can significantly reduce what you can see in a confocal experiment. This article explores causes of autofluorescence as well as different ways to remove it, from simple media fixes to…

Zebrafish Whole Brain imaging with Leica SP8 spectral confocal laser scanning microscope

Zebrafish Brain - Whole Organ Imaging at High Resolution

Structural information is key when one seeks to understand complex biological systems, and one of the most complex biological structures is the vertebrate central nervous system. To image a complete…

What is a Resonant Scanner?

A resonant scanner is a type of galvanometric mirror scanner that allows fast image acquisition with single-point scanning microscopes (true confocal and multiphoton laser scanning). High acquisition…

What is a Spectral Detector (SP Detector)?

The SP detector from Leica Microsystems denotes a compound detection unit for point scanning microscopes, in particular confocal microscopes. The SP detector splits light into up to 5 spectral bands.…

Resolved Field Number (RFN)

The field number (FN) for optical microscopes indicates the field of view (FOV). It corresponds to the area in the intermediate image that is observable through the eyepieces. Although, we cannot…

What is a Field-of-View Scanner?

A field-of-view scanner is an assembly of galvanometric scanning mirrors used in single-point confocal microscopes that offer the correct optical recording of large field sizes. The field-of-view…

What is a Tandem Scanner?

A Tandem Scanner is an assembly of two different types of scanning together in one system for true confocal point scanning. The Tandem Scanner consists of a three-mirror scanning base with the…

See More Than Just Your Image

Despite the emergence of new imaging methods in recent years, true 3D resolution is still achieved by Confocal Laser Scanning Microscopy (CLSM). Through a combination of novel, extremely fast scanning…

Which Sensor is the Best for Confocal Imaging?

The Hybrid Photodetectors (HyD) are! Why that is the case is explained in this short Science Lab article.
