Most people in the scientific community understand that size and shape dictate the absorption and emission properties of quantum dots. This is why optical properties of quantum dots can be easily tuned, leading to their utilization in countless applications ranging from optoelectronics to molecular biology. Not as widely known is that the size-dependent absorption properties…
Read MoreAvantes, Inc. is excited to welcome Jason Peoples as a new addition to our Team. Jason Peoples joins us as our new Regional Sales Manager for the US Western Region. Jason has a strong background in spectroscopy having worked for Analytical Spectral Devices, Inc out of Boulder Colorado. Jason’s friendly positive attitude is a guarantee…
Read MoreBioluminescence from marine microorganisms has been observed by many people at various beaches across the world. A bright bursting energy of light is observed when energy is transferred to the fluorescent protein (GFP). One example of this is in Aquorea Victoria, a bioluminescent jellyfish. The GFP in the Aquorea Victoria is located in a specialized…
Read MoreThe lighting industry has gone through a rapid transition over the past ten years with the commercial success of LED lighting. This boom in LED lighting has been fueled by a trifecta of clean energy legislation, increased luminous flux, and decreased costs. The data in figure 1 shows that LED illumination has finally reached the…
Read MoreIntroduction Because of its size and low power requirements, the AvaSpec CompactLine (affectionately called the “mini”) is often used with a raspberry pi, Arduino, or other single board computer. This headless operation allows for use in portable and hard-to-reach settings. In this tech note, we’ll discuss in more detail setting up the Avantes Raspberry Pi…
Read MoreTransmission spectra can be used in a wide range of measurements and data collection to reveal unique and unknown properties of materials. It is crucial to understand how materials that we interact with behave when exposed to photons across the UV/VIS/NIR spectrum. One excellent example of this is sunglasses. It is important to know if…
Read MoreThis post is the first in a series on “Creating a Python Project for Spectroscopy” In this tutorial, I want to show you how to set up an Avantes spectrometer outside of AvaSoft. This is useful for incorporating spectroscopy into an existing imaging project (e.g., a microscope), or to synchronize with other equipment (e.g., a…
Read MoreWhen a molecule absorbs a photon, it imparts energy to the molecule causing it to temporarily excite from the ground state to a higher electronic or vibrational energy level. Due to conservation of energy, absorption can only take place when the photon energy is precisely equal to the difference between the ground and excited states…
Read MoreThis post is part of a series on “Creating a Python Spectroscopy Project” Developing a customized Python project application to integrate with Avantes Spectrometers is easier than you might expect. Join Justin Spott, regional sales engineer, with a new series of “tech notes” that explores this topic in greater detail. Part 1: Installing the AvaSpec…
Read MoreThe importance of NIR reflection spectra has proven to be a reliable method of identifying unique characteristics and properties of various materials, including types of plastics. Different types of plastics may look similar to one another at an initial glance with the naked eye, but evaluating the NIR reflection properties of plastics can reveal just…
