We supply compact and ultra-compact spectrometers from OtO Photonics.
OtO provides compact Czerny-Turner cavity spectrometers along with a range of unique microspectrometers based on their innovative semiconductor grating chip technology.
This "non-spherical, mass-producible" grating replaces the "collimator-plane grating-focusing mirror" optical structure used in traditional C-T spectrometers and combines grating and focusing functions into one micro-sized component. The microchip concave grating technology 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 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.
OtO spectrometers cover the spectrum from 180nm to 1700nm with CCD, CMOS, back-thinned, cooled back-thinned and linear InGaAs arrays from manufacturers such as Toshiba, Sony and Hamamatsu.
A wide range of standard configurations of detector, grating pitch and slit size are offered 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
As inspection is needed in almost all industries, OTO believe that the dawn of microspectrometers will drive the development of spectral analysis components and relevant electro-optical sectors.
It is also possible to define detector, resolution and bandwidth for specific applications and all OTO microspectrometers can be supplied with WiFi connectivity.
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.
