General Introduction
Attonics Systems is disrupting the field of spectroscopy. Our innovative spectrometers are
based on a novel interferometer design that allows the spectrometer to be as compact as
possible yet comparable to a lab grade spectrometer. Our patented manufacturing technique
enables a new platform for spectroscopy based on interferometry instead of conventional
gratings. By realizing a spectrometer conveniently held within your palm and yet have
research grade precision is a revolution. Our compact, rugged spectrometers are easily
adaptable to any existing optical setup for spectral monitoring.
Unique Features
•
Compact Size
•
Low Cost
•
Interferometer based sensor: High resolution, high throughput as opposed to high
resolution low throughput for grating based spectrometers
•
Wide range spanning the entire CMOS range (380-1020)
•
1 nm repeatability
•
12 nm FWHM (customizable down to 2 nm)
Cost effectiveness and compactness
High resolution and lab grade spectrometers and spectrophotometers are expensive with a
price tag in excess of US$ 20k and difficult to maintain. The cost for using spectrometers as
detectors is, therefore, cost-
prohibitive and many applications can’t affo rd precise spectral
monitoring. We overcome the cost disadvantage while providing high spectral resolution for
process monitoring. The dimensions of the active device are 32 x 32 x 66 mm

making it
ultra-compact and suitable for applications hitherto impossible. Compact size means it can
be easily adapted to any viewport.

Fig. 1 : a) Schematic of a grating spectrometer dispersing a collimated beam of light
impinging on the grating into its spectral components. A detector downstream the grating
reads the individual wavelengths as a function of angle or location. Spectral separation
depends on collimation, dispersion and distance from the grating. b) Schematic of the
Attonics Systems interferometer. A collimated beam of light transmits through a 3-
dimensionally structured micro/nano textured surface. Light rays interfere and form a unique
fringe pattern on an array detector in proximity. The forming fringe pattern are
mathematically translated into spectral information. Spectral separation depends on the
maximum phase delay generated in the textured surface.
