The Yokogawa AQ7420 high resolution reflectometer can analyse the internal structure of optical modules and visualise ...

Optical non-contact profilers are interference microscopes used to accurately measure the three-dimensional height variations on surfaces of a given test material. Optical profilers manipulate the ...

The first order optical system design covered in the previous course is useful for the initial design of an optical imaging system but does not predict the energy and resolution of the system. This ...

Optical sensors can provide either digital or analog outputs. With digital outputs, relative position is determined by counting pulses, and pulse width determines the resolution. Digital versions ...
