It can be used for the characterization of LEDs and lasers, (anti)reflection coating efficiency measurements, for investigations into absorbing materials, fluorescence detection, photovoltaics, and much more.</p> <h3>Optical Absorption</h3> <figure class="float-right"><img alt="Absorbance spectrum sample (also known as the optical density (OD))" loading="lazy" src="https://www.ossila.com/cdn/shop/files/optical-spectroscopy-example-spectra-absorbance.png?v=1657537655&width=560&height=463" width="424"> <figcaption>Example of an absorption measurement taken with the Ossila USB Spectrometer</figcaption> </figure> <p>The<strong> optical absorption</strong> of material will tell you about the wavelengths of light that it will absorb. With this information, along with emission data, you can probe the internal electronic and vibrational structure of atoms and molecules. In some cases, this can give you information about the conformational structure of molecules and polymers within your sample.</p> <p>Absorbance measurements can also be used to calculate the concentration of absorbing species in a sample or monitor the progress of chemical reactions.</p> <p>The ability to measure absorption is critical for applications such as chemical synthesis and analysis, material discovery (for photovoltaics, LEDs, or pharmaceuticals) and quality control.</p> <p>Typically, the spectroscopy light source used for absorption and transmission measurements has a very broad spectrum. Suitable sources include deuterium or tungsten halogen lamps or an LED broadband white light source.</p> <h3>Transmission and Reflectivity</h3> <p><strong>Transmission</strong> and <strong>reflectivity</strong><span> measurements have applications that range from characterising photonic structures such as dielectric stacks (often used as high-reflectivity or antireflection coatings) to process control in manufacturing. They can be used to detect changes in film thickness, density changes, and even the presence or absence of objects.</span></p> <h3>Light Scattering</h3> <p><strong>Scattering</strong><span> measurements are much less common, due in part to the difficulties in predicting and detecting where the light will scatter. With the correct procedures, optical spectrometers can be used to calculate the size and distribution of scattering centers within a sample. They are also useful for impurity detection/monitoring in water systems, nanoparticle characterization and drug loading for pharmaceuticals.</span></p> <h3>Luminescence</h3> <p>Our spectrometer can also be used to measure the emission spectrum of materials and devices. Studying the light that is emitted by a material is a complementary technique to absorption spectroscopy, in that it probes how processes lead to the conversion of internal energy to photons, rather than the other way around.</p> <figure class="float-right"><img alt="Fluorescence measurement taken with a spectrometer using a 45 degree angle" loading="lazy" src="https://www.ossila.com/cdn/shop/files/45-degree-measurement-angle-pl-pfo.png?v=1675076055&width=484" width="424.156"> <figcaption>PFO photoluminescence measurement taken with the Ossila USB Spectrometer</figcaption> </figure> <p>The optical spectrometer can be used to measure various type of radiative emission measurements including steady-state photoluminescence, fluorescence and phosphorescence. In these cases, the compatible Ossila UV light source can be used as an excitation source. Alternatively, you can use a high energy laser of appropriate wavelength. You can also use the spectrometer to measure the emission of light from non-radiative excitation sources, such as for electroluminescence measurements.</p> <p>From emission measurements, you can extract information about the electronic and vibrational states of a material, as well as how these materials are interacting with their surroundings. This information can be used to complement (or as an alternative to) absorption measurements for chemical synthesis and analysis, material characterisation and discovery, quality control, and more. In addition, luminescence also has some unique applications. For example, fluorescent molecules are often used as 'tags' or 'tracers' in applications as far-ranging as understanding the processes occurring within living cells, to identifying the paths of water courses.</p> <p>Optical spectroscopy is invaluable in studying all types of emission. It allows the colour rendering index (CRI) of light sources to be calculated, which is an important factor when developing lighting for specific applications.</p> <h2 id="resources">Resources and Support</h2> <hr> <div class="tile-container"> <div class="card-box"> <h3 class="h4" id="modular-spectrometer">Why Choose a Modular Spectrometer?</h3> <p>Spectrometers (or spectrophotometers) often come in large integrated systems with all components housed in one unit. These have high accuracies and are useful for taking repeat standard measurements – but they also have a large lab footprint and are expensive.
