This paper highlights a range of options to utilize Photoelastic Modulators (PEMs) with imaging systems to generate full field polarimetric measurements. Due to the resonant nature of the polarization modulation, the change in polarization cannot be directly controlled and happens at the natural resonant frequency of the device. Typical resonant frequencies of PEMs are 40 kHz-60 kHz, and as such, the change in polarization is often faster than most imaging systems frame rate.

At Chroma we understand that Raman scattering is a weaker signal that requires much better filters, with steeper edges, in order to isolate the signal of interest. Our Raman filters or sets will cover a wide variety of spectral ranges for your...

How to achieve high-performance 7-channel multiplex imaging, with Kromnigon’s multiband filter technology and CoolLED’s precision-controlled LED illumination.

ASI's VTS-2300 Versatile Test Stand used in conjunction with our Modular Infinity Microscope System.

XYZ Tracker keeps a specimen in the field of view and in focus. It uses ASI’s Tunable Lens and a secondary camera to gather images from different focal planes without moving the objective or sample. It then evaluates those images and automatically...

An overview of the Single-Objective Light Sheet.

Specifications for illumination systems for biomedical imaging and industrial metrology generally converge on spectral, spatial and temporal light output characteristics. This article describes some of the ways in which solid-state Light Engines...

A clever way to overcome the limitation caused by diffraction is to use 'pointillism strategy', a concept introduced by Rainer Heintzmann in 2005. The idea is to have only one fluorescent emitter (fluorophore) present at a given time for a given...

With the evolution of microscopy systems, there has been a concurrent development in microscopy techniques. The first techniques in microscopy were based on Transmitted Light Microscopy. Additional techniques that are paramount to modern...

Many factors affect the price of confocal microscopy systems and when purchasing a microscope, one must consider the complexity of the instrumentation and the capabilities it provides. Clearly the more complex the confocal, spinning disk, widefield...
