Gratings and beam splitters

Description

- Diffractive gratings on thin membranes or silicon wafers

- Different use cases:

   o Beam splitting

   o Grating interferometry

   o Phase contrast imaging

- Wide range of material choices (Si, Au, Ni, SiO2, Ir, Cr, Diamond)

Example

Silicon x ray gratings custom made

Si grating (p=1800 nm)

Specifications

Au grating (p=100-200 nm)

SiO2 grating (p=500nm)

- Gratings can be designed according to customers’ needs using various fabrication approaches
