After Palavas-les-Flots this year, see you in Spain: BETSA® will be exhibiting at the 64th European High Pressure Research Group Meeting, from 5 to 10 September 2027 at ADEIT, University of Valencia.

Come and visit our booth: we will bring demonstration instruments, our latest developments and our flagship products. A good opportunity to talk about your high-pressure experiments with the team. Booth number to follow.

This MH20M electric discharge machine left our workshop in Nangis in 1998. A few weeks ago, a customer sent it back to us. Servicing, cleaning, a board check, a spark adjustment — and it is drilling gaskets again, as precisely as on day one. The video shows the whole process.

That is what we build for. Our machines are designed to be repaired, not replaced: no throwaway electronics, every part machined and assembled in-house, and a workshop that still knows how to service a machine it delivered in the last century. That is also why we guarantee them for up to 10 years — one small overhaul is usually enough to bring a machine back up to date.

The mechanical filter wheel of the BROT can now be replaced by a motorized wheel driven remotely. Built around Thorlabs® ELL14 / ELL14K Motorized SM1 Optics Rotator modules, it sets the laser attenuation from the control software instead of by hand, without opening or touching the optical head.

Straight through, the beam passes at 100 %. A first stage selects one position at a time — direct, OD 1 or OD 2 — and a second stage adds a continuously variable neutral-density wheel driven over 270°, from OD 0 to OD 1. Together they set the transmission anywhere from 100 % down to OD 3. The driver, the relay board and the power supply are integrated inside the BROT enclosure, behind a dedicated front panel.

This option is under development for the BROT V2.25 and has no commercial reference yet. Contact us to discuss your configuration.

BETSA® attended the 63rd meeting of the European High Pressure Research Group, held from 23 to 28 August 2026 at the Phare de la Méditerranée in Palavas-les-Flots, near Montpellier, and preceded by the Pre-EHPRG School on 22 and 23 August.

EHPRG brings together the community we have been equipping for thirty-five years: mineral physics, condensed matter, chemistry under extreme conditions, and the synchrotron beamlines where much of that work is done. We were there to talk about membrane diamond anvil cells, gas loading, external and internal heating, and Raman optical transfer.

Many of you came to find us with the problem you had not solved yet. An optical axis height that does not match an existing bench, a cell that has to fit a cryostat never designed for it, a gasket that fails repeatedly at the same pressure — most of our custom instruments began as exactly that kind of conversation.

Check out our new lineup for RAMAN.

Our latest high-pressure solutions are now on the market! Designed for excellence and built for extreme conditions, our new range is ready to transform your experiments.

Hey there, we’re excited to announce the latest news about BETSA®! Our optical head dedicated to RAMAN for diamond anvil experiments just got an upgrade! The new version, BROTC-02, features improved laser, camera, and other components. Plus, it allows you to independently adjust all filters and elements for even better results. This is the second version of the BROT and we can’t wait for you to try it out in your very high-pressure experiments. Stay tuned for more updates and advancements from BETSA®!

Exciting news from BETSA®: we’ve developed an internal heating system that can reach temperatures up to 1450°C continuously. Our IHS — 3D printed, machined or laser cut — can be customized to fit your specific needs and environment. BETSA® also offers a variety of high-pressure cells to help you conduct your experiments with ease. Stay tuned for more updates from us!
