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 system that is both non-contact and radiation-free. Read more!


Tunable lasers help in the quantum quest

Most early attention has focused on nitrogen vacancy centres in diamond − which offer single-photon emission at room temperature − but they are not ideal for all applications because their asymmetric charge distribution makes them sensitive to local fluctuations in the electric field. Read how our C-WAVE tunable laser helps researchers find new colour centers candidates.


Raman light sheet microscopy

Raman spectroscopy provides an intrinsic label-free contrast mechanism from the sample that is rich in biochemical content. Taking 2D information of the molecular distribution that conforms the sample is thus, very attractive to the biomedical science community. Read about how the unique combination of Raman and light sheet microscopy is helping us learn more.


Quantum sensing

As quantum sensing technology has matured over recent years, one of the contending techniques for commercially developed systems is based on nanoscale magnetometry with Nitrogen-Vacancy (NV) centers in diamond. In this white paper we give an overview of the current proposed solutions for quantum sensors based on NV center magnetometry.


OPO technology

State-of-the-art OPO technology delivers visible, single frequency, tunable laser light from 450 nm – 650 nm. Read about our unique solution to achieve single frequency cw tunable light in the visible to MIR regions.
