For APT Solutions

UM2280 handWe are pleased to announce that AP Technologies has been appointed UK and Ireland distributor for OtO Photonics' full range of spectrometers, light sources, spectral measurement system, accessories and SpectraSmart software.


OtO Photonics was founded as “OtO Science” in 2006 in Hsinchu City, Taiwan with the objective of leveraging Micro Electro Mechanical Systems (MEMS) micro grating technology to develop compact spectrometers. Renamed OtO Photonics in 2010 the company now provides a range of classic Czerny-Turner cavity spectrometers alongside unique microspectrometers based on their innovative semiconductor grating chip technology.


OtO's "SmartEngine", "EagleEye" and "SideWinder" C-T spectrometers cover the spectrum from 180nm to 1700nm with CCD, CMOS and linear InGaAs array detectors including back-thinned and cooled back-thinned technologies.


The "UltraMicro" series of microspectrometers utilise OtO's "non-spherical, mass-producible" grating which replaces the "collimator-plane grating-focusing mirror" optical structure used in C-T spectrometers. Combining grating and focusing functions into one micro-sized component enables extremely compact dimensions as small as 23.2mm x 31mm x 8.5mm (6.1cm³).


The microchip concave grating technology used in UltraMicro-Series microspectrometers leverages patented algorithms to calculate curvature and ray-tracing to eliminate aberrations and achieve high resolution of 2nm. When combined with OtO’s high-precision optomechanical designs and proprietary "SpectraSmart" software the MEMS grating technology enables microspectrometers which push the performance envelope to deliver the benefits of high accuracy, ultra-compactness, shock resistance, weather resistance and low cost making them ideal for high volume deployment in OEM instruments including handheld devices.


OtO's "AirAlliance" series adds WiFi functionality to their full range of C-T and MEMS spectrometers and in combination with SpectraSmart software and SDK toolkits allows connection to up to 5 PC/tablet/smartphone devices (AP mode) and an unlimited number of devices in Client Mode.


All of OtO' spectrometers are offered in a range of standard configurations of detector, grating pitch and slit size to suit common applications:-


  • Electro-optical inspection – i.e. LED testing, solar panel & thin film measurement


  • Colour matching & management


  • Environmental monitoring – i.e. water- and air-quality control


  • Biomedical measurement – Blood & DNA analysis


It is also possible to define detector, resolution and bandwidth for specific applications.


OtO’s unique “stray light calibration” process optimises the performance of standard low cost spectrometers to achieve stray light levels as low as 0.01% - better than models costing $30,000 and upwards.
