Raman spectroscopy terminology guide

On this post we collate some of the Raman spectroscopy terms, along with a short description to help guide through many of the different techniques often used today in the field of Raman spectroscopy. 


Femtosecond lasers for multiphoton microscopy

Multiphoton microscopy has revolutionized biological imaging by allowing high-resolution imaging in 3D without the need for dyes or labels. An important aspect of this technology is the use of very short femtosecond pulses. Read more here!


Ultrafast femtosecond fiber lasers

Ultrafast fiber lasers have revolutionized the field of photonics, offering a range of advantages over traditional lasers. One of the main advantages of using ultrafast femtosecond fiber lasers is the high peak power that they offer, which is a result of their ultra-short pulse duration. Read more here!


405 nm laser for Raman spectroscopy

In this post, read about what performance improvements can be achieved by using a 405 nm laser compared to longer wavelength lasers that are used more conventionally in Raman experiments.


Multi-line lasers for light sheet microscopy

A Multi-line laser is a single compact laser head with multiple lasers built inside and collimated into a single permanently aligned output beam, thus giving the appearance of a single laser with multiple wavelengths. The multi-line laser is therefore very attractive as an extremely compact, an easy to use solution for adding more functionality and wavelengths either to a system design or lab set-up. It is the simplicity and compactness which makes the multi-line laser very attractive for use in light sheet microscopy.


Which 785 nm laser for Raman spectroscopy?

There is a number of different kinds of lasers available at 785 nm. They offer different performance and cost characteristics, which means a careful selection can be important to find the best solution for a particular Raman spectroscopy set-up. In this post we summarise the available technologies around 785 nm.


What does a terahertz imager do?

Until recently, ultrasound and X-ray imaging systems were the only technologies that could look inside a product and detect impurities that are not visible from the outside. Until the T-SENSE was available. It is a terahertz-based syst
