Choosing the right optical model and optical properties to use in your laser diffraction measurements can appear to be a difficult task, especially when you are looking at unknown or mixed materials. In this webinar we will describe the available optical models and their recommended applications. We will also describe some experimental and empirical techniques available for optical property determination, and how these techniques can be applied to real measurements to generate realistic results.
A third installment of our popular masterclass series. Learn from the experts.
