Rez Mani did a M.Eng in Engineering Physics focused on optical properties of semiconductors from McMaster University in Hamilton, Ontario. This followed by a PhD in Earth and Space Science focused on satellite optical instrumentation from York University in Toronto, Ontario. After working in industry for 10 years where he participated in a multitude of optical/laser/spectroscopic projects, he returned to York University as a contract faculty and a research associate in 2011. He has also worked for Allied Scientific Pro as a consultant since 2011 and as an application scientist since 2017.

 Webinar Description:

The webinar will cover several spectroscopic and photometric topics. These include colour temperature, spectral range, CRI index, wave and particle properties of light, black body radiation,  photometric and radiometric units. The Webinar also discusses the new TM-30-18 technical memorandum by IES which uses 99 colours instead of 8 colours to determine colour fidelity. Understanding these basic concepts are essential to improve your knowledge of instruments that are capable of measuring photometric, radiometric and spectroscopic parameters.

Once you are registered you will be receiving a Gotomeeting or webex link and code to get in the webinar, stay tuned!  If you have any questions feel free to email 

Topic: Balancing artificial light for growing tomatoes in different environments three different varieties of tomatoes which were F1 Trust (indeterminate variety large round red tomato) Gold Rave (golf ball size orange plum tomato), and Indigo cherry drop (Black cherry tomato) were grown in three different environments with different sources of light. The first environment was a LED chamber with no access to sunlight, the second, was a greenhouse with supplementary artificial lighting and the third was the outside garden. The quality and morphology of the tomatoes grown in different environments were compared and conclusions were drawn about the usefulness of each wavelength of artificial light for growth of tomatoes. In the past, different varieties of tomato have always been grown using sunlight as the light source for their photosynthesis. The Sun produces a continuous range of wavelengths but not all of these wavelengths are equally needed for the growth of a vegetable. The light intensity, wavelength and photo-period are all important parameters that need to be considered.
Get to know the presenter:   Rez Mani did his PhD from York University in 2001 in satellite spectroscopic instrumentation. He worked in the industry for nearly 9 years, during which he participated in many optical, laser and spectroscopic projects where he worked with many different types of high power lasers such as Nd:YAG, CO2 and Ti:Sapphire.  He returned to York University in 2011 as a researcher and a contract faculty. He currently teaches the course "Atmospheric Pollution" for the department of Natural Science at York University. He has also been collaborating with Allied Scientific Pro as a consultant for more than 6 years and recently as an application scientist for a year.
