Understanding the Photonics Industry
While it is not typically considered vertical industry, Photonics is a horizontal industry which is an enabler for many traditional industries. Photonics is the science of light generation, detection, and manipulation through emission, transmission, modulation, signal processing, switching, amplification and detection/sensing. Spectroscopy plays a pivotal role in many photonics applications. Micro spectrometers offer a great tool for photonics applications because of their portability, durability, affordability, and ability to facilitate in situ measurements through their fiber optic interface. Avantes is a key player in the Photonics industry supporting applications ranging from laser and LED measurements, to filter characterization and quantum efficiency measurements on nanoparticles.
Spectrometers are ideal instruments for laser characterization. They can be used for wavelength validation and beam profiling as well as power measurements. The resolution capabilities of Avantes spectrometers provide for 0.05 nm resolution in the ultra-violet 0.07 nm in the visible and 0.15 nm in the SWIR wavelengths. By configuring a spectrometer with an integrating sphere and radiometrically calibrating the system using a NIST traceable source, power can be measured on a laser. Avantes AvaSphere integrating spheres are compact, high-quality spheres made from machined, high purity PTFE and are offered in three standard internal diameters (30, 50, 80 mm). Avantes unique AvaSpec platform provides for the combination of detectors to cover a broad range. For example, a super-continuum laser (200-2500 nm) can be measured with the combination of the AvaSpec-ULS2048L-USB2 and our AvaSpec-NIR256-2-5.HSC. The image to the right depicts a broadband spectrometer/spectroradiometer designed for the 200-2500 nm range.
Optical component measurement/profiling
Coating operations are frequently required to validate the reflectance and transmittance properties of their filters and other optical components. Avantes instruments are frequently used to characterize filter properties. The ultra-low stray light instruments from Avantes are ideal for this as the effects of stray light can be detrimental to accurate measurements. Avantes offers a variety of sampling accessories to a facilitate optical component measurements of reflectance, transmittance, and absorbance.
LED reliability testing
With the growth of the LED market, manufacturers must monitor their quality and reliability continuously. Avantes modular platform facilitates such industrial solutions for LED testing. The AvaSpec-ULS2048L-USB2 and AvaSpec-ULS3648-USB2 are used in many of these environments where reliability testing may last for hundreds of hours. Calibrated systems can measure a variety of parameters such as X, Y, Z, x, y, z, u, v, CRI, Color Temperature, Dominant Wavelength, Complementary Dominant Wavelength, FWHM, Centroid, Peak Wavelength, and Purity. In order to support large-scale operations, a single spectrometer may be utilized to measure up to 16 devices in a serial manner utilizing the AvaFOM - Fiber optic multiplexer.
All Avantes instruments are available as laboratory instruments in single channel housing or multi-channel "rackmount" housings as well as OEM modules (see below). Requests for customization are welcome.
Fibers and Probes
In many cases, fiber optic sampling is useful to photonics applications. Avantes offers a complete line of fiber optic and sampling accessories to facilitate your measurements. Requests for customization are welcome.
