Developed for ESA’s future X-Ray space telescope the Athena, the optical filter using Canatu CNT could enable further visibility to space. See press release.

Canatu’s ultra-thin optical filters have high EUV/X-Ray transmittance, while being strong to endure mechanical stress such as differential pressure and vibration. They also have high heat resistivity and are chemically inert.

Proc. SPIE 12181, Space Telescopes and Instrumentation 2022: Ultraviolet to Gamma Ray, 121814H (31 August 2022); doi: 10.1117/12.2631516

Canatu CNT membranes are ideal for optical filter applications due to their high EUV and X-Ray transmittance, resistance to pressure differentials, and chemical inertness. These optical filters allow certain wavelengths of light (e.g. X-rays or EUV) to pass through while blocking others (e.g. visible, infrared, or deep ultraviolet). They can be used in EUV lithography to filter specific wavelengths or in front of X-ray detectors to block unwanted particles, electrons, and photons, all while withstanding high temperatures and pressure differentials.

EUV pellicles are membranes used to protect the photomask from contamination while permitting high EUV transmission. EUV pellicles made of Canatu CNT offer unique benefits unparalleled by other materials. See product.

This LED lighting kit includes two cold shoe mounts and a 1⁄4”-20 mounting option for attaching an array of accessories, like mobile phones, digital cameras, and action cameras up to 10 pounds. All of the ring light kit components are lightweight and fit into the included carry case for easy travel and storage.

Since 2020, Canatu has partnered with the European Space Agency (ESA) to develop an X-Ray filter for the ATHENA telescope, allowing precise celestial imaging by enabling X-Rays to pass through while blocking other wavelengths. Traditionally, X-Ray filters use metal meshes for mechanical support due to their fragility. Canatu has introduced a novel all-carbon support structure in partnership with Ametek Finland Ltd. and the University of Palermo, replacing the traditional metal mesh and enhancing X-Ray transmittance.

Canatu CTO Ilkka Varjos presented free-standing CNT membrane platform technology at SPIE Photomask + EUVL 2021. His talk focused on the unique qualities of Canatu CNT, extensive customizability of the CNT synthesis and post-processing, and application potentials. See press release.

These membranes are created from Canatu CNT, renowned for its exceptional purity and properties. Canatu CNTs are synthesized in a floating catalyst chemical vapor deposition (FC-CVD) reactor, and then dry-deposited onto an open frame or a border. With more than a decade of experience in large-scale production of CNTs, Canatu excels in controlling the process and tailoring CNTs for different uses.
