Electron Microscopy

Electron microscopy utilizes an electron beam to study the properties of the sample. Includes scanning electron microscopy (SEM).

Spectrum analyzers

Spectrum analyzers are used to measure the power of an optical spectrum over a specified wavelength (frequency) span.

Spin coating

Spin coating is a method to apply a uniform film onto a solid surface by using centrifugal force and requires a liquid–vapor interface.

Continuous wave

Continuous wave lasers are emitting constant radiation usually with very small spectral bandwidth. They are often used for alignment and sensing purposes, if tunable, can be used for spectral measurements. In the most powerful versions, they are used as optical…
