Science and Creativity Come Together with Spectroscopy and Pyrotechnics

Ocean Optics’ spectrometer assures special effects color purity and safety for Le Maitre
Dunedin, Florida, USA (July 31, 2015) – Spectrometers from Ocean Optics are being used by Le Maitre Ltd (Surrey, England) to ensure the quality and safety of its close proximity pyrotechnics. Ocean Optics spectrometers measure plasma emission and emissive color of effects used in theater productions, concerts, and sporting events. The measurements help Le Maitre ensure these explosive displays are consistently amazing, and most important, safe.

Pyrotechnic spectrometer

Le Maitre Pyrotechnics Developer Hamish Cavaye, Ph.D., runs pyrotechnic tests with an Ocean Optics spectrometer.

Le Maitre Pyrotechnics Developer Hamish Cavaye, Ph.D., runs live product tests in a silo in rural England. His challenge is to objectively verify that effects are producing the desired colors. As was recently proven with the pop culture “What color is the dress?” phenomenon, the human eye is easily fooled. Using a spectrometer to verify color purity, Cavaye looks for particular emission bands indicative of a specific chemical composition.

Measuring the emissive color of pyrotechnics with a spectrometer also has the ability to signal safety issues. If the spectra identify elements that are not expected, it may indicate contamination. Verifying consistency not only ensures a pleasing color for the audience but helps assure the safety of patrons and performers.

Measurement speed is also important in testing pyrotechnics, as some effects can last less than a second. With integration times on some Ocean Optics spectrometers as low as 1 ms, Cavaye can easily capture multiple spectra for each effect. Along with needing the precision and accuracy typically required of spectrometer measurements, Le Maitre had the additional challenge of requiring an instrument that was portable and durable. Compact miniature spectrometers can easily be brought to the testing silo and are rugged enough to withstand close proximity to live effects as they are firing.

Ocean Optics recently visited Le Maitre to see its spectrometers and Le Maitre’s effects in action. Watch the explosive video here: http://youtu.be/Nw0bNfNUYuQ?a.

This isn’t the first time Ocean Optics’ spectrometers have felt the heat. They’ve also been used for studying muzzle flashes from rifles, rocket plume emissions, and applications involving flame analysis of metals and other materials.

Dynamic Sampling Accessories Provide Measurement Consistency

Ocean Optics spectroscopy tools ideally suited to inhomogeneous samples
Ocean Optics has introduced a line of spectroscopy accessories that makes dynamic sampling measurements simple and reliable for both solid and liquid samples. Dynamic sampling is a technique where rotational or linear motion is used to measure an “average” signal across the sample, removing localized variance from results and improving measurements of inhomogeneous and irregular samples such as grains, feed and soil.

Ocean Optics Dynamic Sampling

Ocean Optics spectroscopy accessories make dynamic sampling measurements simple and reliable for both solid and liquid samples.

Ocean Optics offers four dynamic sampling accessories – a diffuse reflectance probe, rotating sampling cup, multiplexer and flow cell – that fit seamlessly with existing UV-Vis and NIR spectrometers and accessories, resulting in a system optimized for the user’s application. Dynamic sampling accessories are ideal for users who take routine measurements of the same sample types or need to measure a large number of different samples frequently.

The Diffuse Reflectance Probe (DR Probe) integrates a light source and collection optics into one unit to measure 45° diffuse reflectance. It is ideal for applications such as color analysis, material identification and quality monitoring of foods. The DR Probe has rugged, all-metal construction with 40 mm focal length and an integrated, 10,000-hour bulb for extended time between servicing.

Also available for diffuse reflectance measurements is the DynaCup, a rotating device that presents samples to the DR Probe. The rotation allows the probe to scan the sample multiple times to collect a more consistent, representative spectrum of the sample. This method is important with inhomogeneous samples like grains, where variables such as shape, moisture and starch distribution within kernels can vary greatly.

To save sample measurement time and streamline sample processing, the multiplexer accessory is a mechanical actuator that distributes light through 10 customizable channels from a single light source. The multiplexer is useful for any kind of light transmission and optical fiber size. Two models offer a choice between fast positioning, or high repeatability and accuracy of performance. The multiplexer features SMA 905 connections and a USB port for communication and remote control.

For flow applications users can select the DynaFlux, an integrated transmission and absorbance flow cell. DynaFlux accepts standard transmission cells with pathlengths up to 10 mm (sold separately) and a temperature controlled sampling chamber. A programmable timer allows the flow cell pump to run for fixed times with options for continuous flow to analyze large volumes, or stop-flow mode to analyze static samples. DynaFlux is an all-in-one accessory for dynamic sampling of liquids, for both NIR and UV-Vis transmissive measurements.

Spark-VIS Spectral Sensor

Spark-VIS spectral sensor with Spark accessories.

The Spark-VIS is the first Ocean Optics spectral device to replace traditional diffraction gratings with a solid-state optical encoder. The resulting unit size and cost are comparable to that of a less robust RGB filter diode detector, but with the ability to take full spectral measurements. Compatible with Ocean Optics’ Raspberry Pi development kit, the Spark-VIS can be purchased off the shelf for applications engineering. The same spectral sensor can then be purchased economically in bulk for use as a component in portable and Internet-enabled devices.

The stand-alone Spark-VIS is easy to use, with plug and play USB connectivity. Its low cost makes it a good option for budget-conscious student labs. The even smaller OEM version runs off the host device’s driver and communication electronics, connected by ribbon cable. A line of Spark accessories, including clip-on cuvette holders, diffusers, and light sources, is compatible with both versions.

Spark has remarkable performance for a spectral sensor of its kind. Its aperture design optimizes light throughput. Robust optoelectronics ensure thermal stability over a -10° – 60° C operating range, for accurate analysis even in harsh environments. Unlike comparable devices, Spark delivers optical resolution of 4.5-9.0 nm (FWHM), making it viable for a wide range of applications.
