Success Stories

LED Solar Simulator - Student project with Ryerson University

An undergraduate student undertook a research project to develop a solar simulator using only LEDs. The student was able to develop a prototype under the mentorship of his supervisor and our experienced engineers. The prototype helped to inform a current LED solar simulator design we are now manufacturing, bringing benefits to both parties.

SPS-300 – Product Development with McMaster University

Developed to respond to custom research needs, we partnered with an expert in FTIR and THz spectroscopy. A product was developed for the immediate need, which quickly matured into a full-fledged product line for specialized spectral requirements. Now, a large number of accessories and different methods can be appended to the main system.

Clean Room

  • In-house clean room
  • Up to ISO 5 available
  • Applications: pharmaceuticals, aerospace, automotive

Sciencetech’s manufacturing unit is equipped with an in-house clean room which is used to manufacture and test equipment to comply with clean room standards.

Products we have manufactured in this environment include: our far infra-red spectrometer, solar simulators and light sources (aerospace applications), and spectroscopy systems (standards institutions and aerospace applications).


Contaminants that are produced by living organisms, machinery, and other equipment can have dire effects in highly sensitive testing environments. Clean rooms are often used to protect contamination-sensitive procedures.

Equipment to be operated in clean rooms also needs to be manufactured in a clean room environment, to prevent the instrument itself from introducing particles into the testing environment.

Clean room requirements are standardized in such a way that the concentration of airborne particles in a clean room is known, limited, and controlled. Clean room standards are classified according to the number of particles found per cubic meter at a specified particle size.


The most well-known and often requested standards are classified under ISO 14644-1:

Class Maximum Particles/m² FED STD 209E Equivalent
≥ 0.1 µm ≥ 0.2 µm ≥ 0.3 µm ≥ 0.5 µm ≥ 1 µm ≥ 5 µm
ISO 3 1,000 237 102 35 8 Class 1
ISO 4 10,000 2,370 1,020 352 83 Class 10
ISO 5 100,000 23,700 10,200 3,520 832 29 Class 100
ISO 6 1,000,000 237,000 102,000 35,200 8,320 293 Class 1,000
ISO 7 352,000 83,200 2,930 Class 10,000
ISO 8 3,520,000 832,000 29,300 Class 100,000
