Alcorix Products | Micro and nanofabrication devices

Empowered by Alcorix devices, researchers can see and do more in the nanoscale range.

Inspired to innovate precision micro and nanofabrication solutions, Alcorix has developed a proprietary portfolio of novel devices, techniques and processes that deliver a whole new level of ultra-precision and accuracy. Our devices can detect, discriminate, image, manipulate, and deliver materials at lower and lower size scales. Our products include precision focusing devices, beam blockers, resolution targets and pinhole apertures, with other products under development such as high-pressure cells, microprobes, microsensors, and other microfabricated tools.

Beam Blockers

A beam blocker is a blocking filter for low spatial frequencies. In X-ray imaging systems, it usually blocks the zero-order diffracted beam in order to provide a shadow cone obturating the direct passed beam. Beam blockers are made of an absorbing gold cylinder placed on a transparent membrane. The height of the cylinder needs to be configured to sufficiently absorb the radiation, while the diameter has to be adapted to the optics. Alcorix has a variety of standard configurations, and can work with you if you need to develop a customized solution.

Resolution Targets

Resolution Targets

Resolution targets are reference line patterns with well-defined spacings and thicknesses that are used to measure the resolution of imaging systems. The Alcorix resolution targets include both Cartesian- and Polar-coordinate micrometer-scale patterns.

Pinhole Apertures

Pinhole Apertures

Pinhole apertures are meant to shape the beam or filter the low spatial frequencies in X-ray optics configurations. Their diameters vary from few hundreds or tens of micrometers when used as field apertures, to few micrometers when used as order sorting apertures. Pinhole apertures are made in > 60-micrometer-thick gold disks, and can have customizable high-precision diameters. Gold disks can be free-standing or attached to larger Si handling chips. Alcorix has a number of standard configurations and can work with you if you need to customize for different shapes and thicknesses of apertures.

Sawtooth Focusing Devices

Sawtooth Focusing Devices

Sawtooth devices are a type of compound refractive lens that are particularly useful for focusing high energy (15 kev to hundreds of keV) X-rays. Alcorix offers several products in standard configurations that can produce down to sub-micrometer focal spots. Aberration-corrected versions are being developed.

$Diffractive X-Ray Optics$

Diffractive X-Ray Optics

Alcorix develops a series of diffractive X-ray optical devices, including zone plates for soft and hard X-rays, including for high photon energies. Other devices include multilayer Laue lenses (MLLs), optical vortexes, gratings, slits, and coded apertures. While some devices are available in stock, others are under development.

UNCD TEM Grids

UNCD grids allow interference-free EDS analyses of most atomic elements of interest in TEM samples. Specialized UNCD grids with various mesh configurations are available. Grids with graphene membranes are also possible.

High-Pressure Fluid Cells (HPFC)

High-Pressure Fluid Cells (HPFC)

Fluid cells for 3-30 MPa were developed for covering an intermediary pressure domain necessary for studying chemical and biochemical reactions using X-rays or other beams transmitted through a membrane-limited cavity that can be also a reaction chamber for in situ observation.
