We won't be at Photonics West 2022

Unfortunately, we have to cancel our participation at Photonics West 2022 due to Covid19.

We would have been very pleased to meet you in person and to exchange ideas with you. Given the rapid rise in Covid19 cases, we have made the difficult decision to withdraw from exhibiting at Photonics West 2022.

Of course our Heraeus experts would still like to get in touch with you about your current challenges. If you would like to schedule a virtual meeting, please contact us:
