Light coherence, an elusive concept

In this article we are going to introduce the concept of coherence, as it plays a major role when selecting a light source for a certain application. It is always mentioned in the articles about light sources in the domain of fiber optics but it isn’t clearly explained most of the times. Although it isn’t… Seguir leyendo Light coherence, an elusive concept

Fiber optic fluorescent sensors heavy metal ions

The risks associated to water contamination are very important for human health and environmental protection. Therefore, water quality monitoring is a major concern of current society. In this sense, the efforts of the last years have been dedicated to the development of fast, sensitive, and selective sensors for the detection of heavy metal ions. Among… Seguir leyendo Fiber optic fluorescent sensors heavy metal ions

SLD lighting principles unveiled

Superluminescent diode (SLD/SLED) lighting principles unveiled Nowadays, lasers and LEDs are part of the everyday life thanks to the Star Wars lightsabers or the low consumption bulbs, although a non specialized public will find difficult to explain accurately the difference between both. Nevertheless, if you google SLED without any reference to optoelectronics, the result will be related… Seguir leyendo SLD lighting principles unveiled

Relative measurements

Insertion loss and return loss or power signal transmitted along a fiber optic link, are generally expressed in dB (decibels) and should always be a positive number. But they can also be negative, which is not good in terms of optical communications but could be useful for other applications.   Let’s clarify the meaning between… Seguir leyendo Relative measurements

Fundamentals of fluorescence measurements

The use of fiber optic sensors based in fluorescence measurements has become a common practice for applications of detection in areas such as analytical chemistry, biochemistry, cell biology, photochemistry, medical diagnostics or biotechnology during last decades [1]. Fluorescence-based sensors present high sensitivity and specificity, being the design and manufacture of the appropriate sensitive coatings one of… Seguir leyendo Fundamentals of fluorescence measurements

Fiber optic connectors – types and significance

Turn your fiber optic transmission setup to a reflection setup

Optical fiber setups can often be very complicated and hard to be moved from laboratory to real life applications because of bulk measuring equipments or brittle optical fiber configuration.   From the point of view of the fiber coupled light source equipment PYROISTECH offers robust and compact solutions that cover the entire spectrum from ultraviolet… Seguir leyendo Turn your fiber optic transmission setup to a reflection setup

Proper optical fiber selection is crucial for your application

When using a fiber-coupled light source, such as our COB-SERIES or FJORD, it is essential to select carefully the right fiber to use with. We all have in mind the differences between single mode and multimode fibers (core/cladding diameters) and optical fiber configurations (bifurcated fibers, splitters, couplers, etc.) among our bunch of fibers. Nevertheless, it… Seguir leyendo Proper optical fiber selection is crucial for your application
