Phase Rings

For phase contrast imaging applications

Zernike Phase Rings

Zernike phase rings are used for phase contrast imaging along with our zone plates to achieve high resolution, high-contrast imaging of biological and other samples. Rings of varying materials, thickness and diameters are available custom-made for your application.

Materials

Phase rings of varying materials and thickness can be made on thin membranes for your application. Contact us for more information.

Custom Designs

Custom designs with multiple phase rings on a single membrane can be made to test different parameters.

Membranes

Phase rings can be fabricated on various ultra-thin membranes of silicon nitride, silicon carbide, and silicon from 50 nm to 1 µm in thickness for soft to hard X-rays.

Chip Sizes

Custom chip sizes can be made. Our typical substrate size is 5 mm x 5 mm, but custom sizing is possible.
