Organized by SPIE and sponsored by Photonics Media, the international awards competition has, since 2008, recognized the best new products on the market. The event is a celebration of the industry and its many innovative companies.
Company: Avotec Inc. (Florida, U.S.)
Product: Real Eye Nano
The Real Eye Nano offers visual presentation and eye tracking in high-field magnetic resonance imaging (MRI) applications. The device represents an order of magnitude reduction in size from previous technology, which allows it to be positioned and operated in very confined MR head coil spaces, dramatically increasing eye-tracking performance. It works by illuminating a patient’s eyes with NIR (980 nm) light supplied by an IR LED/fused fiber cable/fiber bundle system. The reflected IR is collected by a miniature multi-element lens and imaged onto a wound bundle image guide, which is then coupled to an MR-compatible IR camera. The output of the camera is relayed over a fiber optic link to an eye-tracking computer yielding a speed of 240 Hz.
Company: Biodesy Inc. (California, U.S.)
Product: Biodesy Delta
The Biodesy Delta — comprising an optical instrument with liquid handling robotics, a custom 384-well microplate with integrated prism optics, proprietary reagents and software — is an optical system based on the Second-Harmonic Generation (SHG) nonlinear optical process. The system reveals static protein structures in motion in their native environment, as an ultrafast mode-locked Ti:S laser excites the SHG signal and detects protein conformation instantaneously. The system’s full automation enables real-time detection following ligand injection with throughput of thousands of measurements per day.
Company: Convergent Dental (Massachusetts, U.S.)
The Solea CO2 laser system is designed for use on all tissue (soft, hard and osseous) and is the first computer-aided preparation system for dentistry. The laser’s 9.3-µm wavelength can be highly absorbed by hydroxyapatite, improving speed and precision for dentists. Unlike other traditional dental experiences, Solea offers “virtually soundless, painless and sensationless” procedures, and essentially replaces the drill as the primary tool for tissue procedures. This represents a major step forward as the system can execute multi-quadrant dentistry in a single appointment.
Detectors and Sensors
Company: Alakai Defense Systems Inc. (Florida, U.S.)
An eye-safe standoff Raman instrument, the PRIED sensor features reflected laser beams that can be employed in any environment, while increasing eye safety. By utilizing deep-UV Raman, PRIED overcomes disadvantages of traditional Raman technology; the device’s detection times are 1 to 10 seconds even when the operator is 10 m away, and has been shown to detect explosives in a 50-m range in less than 20 seconds.
Company: Hamamatsu Corp. (Massachusetts, U.S.)
Product: MEMS-FPI Spectrum Sensor
Suitable for embedded OEM applications, the MEMS-FPI Spectrum Sensor is a more compact and less expensive option for measuring NIR spectra than a multichannel detector and associated optics. It is composed of a miniature Fabry-Perot interferometer (FPI), which is fabricated through MEMS technology, and an InGaAs PIN photodiode. The interferometer acts as a tunable filter that scans through a range of wavelengths, and each wavelength that passes through the FPI is detected by the InGaAs PIN photodiode. Currently, the wavelength sensitivity range is 1550 to 1850 nm, but it can be extended to other wavelength ranges based on application demands.
Company: Spectral Engines (Helsinki, Finland)
Product: Wireless IR Analyzer
Inexpensive and simple, the Wireless IR Analyzer sensor is fast and stable with a resistance to shocks, vibrations and wear, thanks to a monolithic, off-plane micromechanical Fabry-Perot interferometer. And unlike conventional spectrometer schemes, it requires only a single-point detector rather than a linear array. The robust IR spectrometer system is compact with a high throughput, and is capable of covering IR ranges above 1.7 µm without any loss in performance.
Displays and Lighting
Company: Crystal IS (New York, U.S.)
Product: Optan SMD
Optan SMD is an environmental sensor that provides an increase in instrument maintanence intervals by preventing biofilm (a thin film of bacteria) from forming on surfaces. Based on native aluminum nitride (AlN) substrates, the new sensor is environmentally friendly; conventional systems have historically used copper coatings and chemicals that have been deemed toxic under newer environmental regulations. Also, the Optan SMD’s compact footprint allows for design flexibility and integration into instruments of all sizes.

The complete system works in tandem to offer a state-of-the-art cinema experience.
Company: QD Laser Inc. (Kanagawa, Japan)
Product: Retinal Imaging Laser Eyewear
Unlike conventional smart glasses and head-mounted displays, the Retinal Imaging Laser Eyewear draws images directly onto the retina, making picture clarity independent of the user’s visual acuity and point of focus. A miniature laser projector inside the frame provides digital image information, essentially using the retina as a screen by the combination of red, green and blue laser diodes and a MEMS mirror. The device’s laser imaging has good color reproducibility, high dynamic range and a low energy profile. The augmented reality images can be seen without any focusing gap.
Imaging and Cameras
Company: First Light Imaging (Meyreuil, France)
Product: C-RED One
C-RED One is an ultra low noise, fast SWIR Camera that uses a 320 × 256-pixel e-APD (Avalanche Photo Diode) sensor with a 24-µm pixel pitch. It combines frame rates of 2000 fps and sub-electron readout noise simultaneously, with the aid of the APD detector technology made of HgCdTe photodiodes offering noiseless amplification of the signal by single electron multiplication. The majority of IR cameras on the market use InGaAs sensors, along with low cooling, but these are not sensitive after 1.5 µm and provide a readout noise that is higher than what C-RED One produces.
Company: Rochester Precision Optics (New York, U.S.)
Product: CNOD (CMOS Night Observation Device)?
The CNOD is a fully digital system offering true digital night vision sight; it is not a thermal system. It can be used as a handheld monocular, a clip-on in-line weapon sight or a stand-alone weapon sight. Currently, no image intensification night vision sight or thermal sight exists that can perform all of these functions. It can see through glass, features very low halo and external light bloom, and enables IR laser detection and full facial recognition.
Company: Stream Technologies (Edmunton, Alberta, Canada)
