Lock-in amplifiers are important tools for material and device researchers because of their unique ability to precisely measure signals that are otherwise too small to detect amidst noise and other interfering signals. This singular capability makes them indispensable in a wide range of low-level measurement applications in the lab. However, researching and evaluating lock-in types for purchase can be confusing. This paper aims to simplify the selection process.

Time-domain spectroscopies based on the optical Kerr effect (OKE) offer insights into the ultrafast processes that determine the fundamental properties of material and biological samples. Until recently, OKE has been restricted to laboratory settings due to the lack of compact, commercially available femtosecond lasers with sub-50 fs pulse durations. This whitepaper demonstrates the capabilities of these advanced, fiber-based femtosecond lasers for OKE, highlighting their potential to expand the technique’s applications beyond the lab.

Finding the ideal ultra-fast laser source for a multiphoton imaging setup is not trivial. It is a fine balance between peak power, pulse energy and laser wavelength. In this white paper we discuss important laser parameters and the impact these laser parameters have on the quality of the results.

In the constantly evolving field of ultra-high resolution tomography, x-rays are used to create nondestructive, high-resolution images of a sample at the sub-100 nm level. Precision motion equipment, such as linear and rotation stages, position and manipulate the various elements in a tomography experiment, including the sample that is being imaged, the x-ray beam, and the detector of camera. As x-ray beam cross-sections shrink and detector resolutions improve to nanometer-levels, the positioning performance of the motion equipment must be better than the desired resolution and measurement accuracy. This article will review the motion elements used in a typical synchrotron end station and discuss critical items that designers and engineers must consider when attempting to achieve reliable ultra-high resolution tomography results.

LIBS analysis is now being adopted as an attractive technique in a wide range of industrial applications: from sorting recycled metals to identifying future mining areas. In this white paper, we introduce a very compact, air-cooled, pulsed laser and show it can be used successfully in conventional LIBS experimental set-ups for identifying metals.

For decades, cationic UV curable adhesives and coatings have brought simplicity and consistency to the manufacturing space. Available as stable, single-component systems, UV curables require no precise weighing, mixing, or pot-life monitoring. With an unlimited working time, parts can be assembled with less operational constraints and greater consistency. The cure-on-demand nature of UV is fast, convenient, and especially advantageous for joining thermally sensitive substrates.

This whitepaper provides a comprehensive introduction to correlative Raman techniques and describes five key factors to consider when evaluating instrumentation: speed, sensitivity, resolution, modularity, and combinability are some of the characteristics that can be used to identify a high-quality Raman…
