Lasers for Machine Vision: Selection Criteria

Interested in adding machine vision into your system? Wanting to make improvements to your current machine vision setup? After reading this article, you will have a better understanding of the characteristics that need to be considered when defining a laser module for machine vision. These characteristics include laser output power and stability requirements, wavelength options and cost/specification considerations, beam shaping options to get the preferred line or illumination pattern, external environmental requirements to consider, and OEM versus turn-key … Read More

Fundamentals of Confocal Raman Microscopy

After reading this white paper, you will come to understand the fundamental relationship between the conjugate pinholes and how they determine the depth resolution of the system.  You will understand why these type of microscopes can produce such high-resolution images, and why that requires a laser which is both a single spatial and single longitudinal mode.   We go on to explain that, for these reasons the 532nm single longitudinal mode (SLM) diode-pumped solid-state (DPSS) laser from Oxxius, with excellent TEM00 beam quality makes it an ideal source for integration into confocal Raman micr… Read More

Single Frequency Fiber Lasers for Doppler LiDAR

After reading this white paper, you will come to understand the fundamentally entangled relationship between the range and velocity resolution of a lidar system and why it is so important to use single frequency laser sources for velocity measurement. This article will further go on to provide a brief overview of fiber laser technology and explain why they have become the light source of choice for most commercial lidar applications. Lastly, in the article, the LRL2 single frequency fiber laser from BKtel is presented as an example of the types of specifications required to lay the foundation for a successful Doppler lid… Read More

Multi-Wavelength Laser Sources for Multi-Color Fluorescence Microscopy

Multi-color fluorescence microscopy is a widely used technique to generate multi-spectral images of cells and other small objects for identifying the spatial distribution of molecules of interest in complex heterogeneous samples. In this article, we explore the history of fluorescence microscopy, with a heavy emphasis on the importance of utilizing multiple fluorophores (tags) in the same measurement. This article will further go on to explain that to alleviate the challenges of integrating multiple lasers into a single microscope, RPMC Lasers offers the LaserBoxx LXCc Combiner from Oxxius, in which up to seven different lasers can be dichroicly beam combined and coupled into a single-mode fiber op… Read More

CW Solid State Laser Sources for the Life Sciences: An Introduction to selecting a laser module for your experiment or instrument.

As lasers become more commonplace in many applications within the life sciences, including Super Resolution Imaging, Confocal Microscopy, Flow Cytometry, DNA Sequencing, and Optogenetics, many times the engineer or researcher knows the key parameters needed, but has difficulties sorting out the less important parameters. This could have a significant impact on cost, the experiment, or overall performance of the system. We will present the basic CW laser module characteristics required for Life Science applications and how to define the specifications to insure you get the right laser for your application. Whether you are a researcher working on an experiment or an engineer developing an instrument for one of these applications, understanding the laser source is critical for you… Read More
