Who is Spectrolytic
 Spectrolytic was founded in 2012, to exploit the results of a PhD project
related to a mid-infrared oil sensor for gearboxes in wind turbines
 Initially an IP only company with all operations located at Comline, it became
a fully operational commercial entity in 2015 to enable further growth with a
clear strategic focus on providing cost effective spectroscopic solutions.
 All current spectroscopy products are still produced at Comline utilizing their
expertise in manufacturing electronic products for harsh environments
 Spectrolytic also offers bespoke MEMs / process development service in its
cleanroom facilities. The process development activities are carried out by
world class trained MIT / Cambridge physicists and material experts.
 A privately held and self-funded operation with continued positive growth year on year
and offices in Germany, US, UK and Spain.

What is mid-infrared spectroscopy
• A broad band emitter shines light through a samples
• The molecules in the sample will absorb certain wavelength of the light whist others pass through the
sample
• The wavelength of the light that is absorbed by the sample can be linked to certain molecular
structures that unequivocally identifies the molecules.
• Typically light in the wavelength range from 2.000nm to 12.000nm (mid infrared wavelength region)
provides the highest absorption signal whiles still providing a unique molecular identifier
• Monitoring the changes in the absorption spectrum of a sample over time provides information about
the concentration of relevant molecules in the sample.

-Light is emitted from broad band source
-Light penetrates cuvette with sample fluid/gas
-Certain wavelength get absorbed by sample
-Light is separated into its spectral components by
Linear Variable Filter (LVF)
-Signals (as function of wavelength) are detected with sensor
-Light is emitted from broad band source
-Light is coupled into an ATR crystal
-Sample fluid is placed on top of ATR crystal
-Light bounces in a controlled way through ATR crystal
and interacts with the sample on its surface
-Certain wavelength get absorbed by sample
-Light is separated into its spectral components by
Linear Variable Filter (LVF)
-Signals (as function of wavelength) are detected with sensor

Analysis of raw milk (Agriculture)
• The analysis of the raw milk as
close as possible to the cow is
very important:
• Milk quality provides instant
information about health of cow
• Milk quality can be used to
optimise feeding of cows
• Provides the farmer with
information about the quality of
the milk
• Additional parameters that can be
measured are fat content, protein
content, milk contamination (urea,
melamine) and many more
Lactose concentration in raw milk

Differentiate cancerous from non-cancerous samples
• Infrared absorption spectra of all
samples are shown on the right.
• Offset shifts in y-direction are due to
variability in sample preparation.
• The Partial Least Square (PLS1)
method was used to analyse the data
using SphinxSuite
• Analysis of mid-infrared absorption
spectra allows to differentiate between
cancerous and non-cancerous
samples
• R2 = 0.9 with limit sample numbers
• 5 principle components
Cancerous
Non -Cancerous

Spectrolytic‘s products can address all required
measurement needs
Spectrolytic current products address many of the relevant measurement problems
related to oil condition monitoring
Infrared absorption measurements of samples are a recognised and well established
technology
Spectrolytic products moved this technology out of the laboratory into the field /
processing plants
Next step is to bring this powerful technique to more mainstream application by
maintaining the accuracy of the measurements but bringing down the costs.
We believe the automotive & industrial market are very interesting market segments
and we currently identifying suitable partners with market insight and sales channels

Product Road Map
Industry 4.0 demand lower cost per measurement for the IoT of things
Government & regulators impose ever stricter environmental controls requiring novel
engine / software solution.
Non complying becomes increasingly difficult after VW scandal
Spectrolytic & partner(s) provide route for a cost effective sensor solution
to solve many challenging measurement problems

19. 19
Spectrolytic‘s cost effective sensor solution
Many applications use the same oil and therefore the absorption spectra from engine
to engine are very similar
Spectrolytic has developed a software that identifies key wavelength bands for each
relevant oil parameter for a specific oil type.
These parameters can then be translated into an application specific oil sensor
being able to measure any number of oil parameters.
These oil sensors can be very robust, accurate and cost effective
The same concept described above maps onto any other application

Summary
Spectrolytic has an exciting technology that addresses many problems that are
currently relevant in the automotive and industrial market segments
Applications we are already working on are oil condition monitoring,
gas detection, medical (cancer & COPD) and milk analysis
The technology is scalable, proven and can meet the cost targets required for
automotive and other high volume applications
Spectrolytic is currently evaluating additional partners with relevant market
knowledge and sales channels to enter high volume industrial & automotive
makets.
