Project Description

SLM Research Kit 4K (SRK4K) – JD7714

The SLM Research Kit 4K (SRK4K) offers 2π phase retardation at different selectable wavelengths at resolutions of 4096 x 2400 pixels. The SRK4K is compact, and can aid in the development of a wide-variety of applications including DOE, HOE, laser processing, holography, WSS, and data storage (HDS) applications. SRK4K accessories include the wavelength configuration software and all required cabling.

The included SRK Config Manager software allows the user to configure both the wavelength and retardation of the SLM. The software runs on a Windows PC which is connected to the SLM via a USB cable. Two native and one user configuration allow for a convenient and flexible way to work with a variety of light sources.
