Diffraction Gratings: Flexible Design Options

Wasatch Photonics VPH gratings offer optical and instrument designers a tremendous amount of flexibility to optimize performance for a specific application. In this tech note, we’ll discuss the benefits of the various standard and patented grating design technologies at our disposal, and the general grating parameters we can control to meet your specific needs.

Tech Note: Raman Sample Coupling

Raman spectroscopy involves delivery of a high intensity of laser light to a very small focus, while simultaneously requiring sensitive detection of less than one-millionth the number of scattered photons. How that light is delivered to and collected from the sample has a significant impact in the quality of data […]
