Quality Assessment and Reproducibility
for Instruments & Images in Light Microscopy

The QUAREP-LiMi is a group of enthusiastic light microscopists from Academia and Industry all interested in improving quality assessment (QA) and quality control (QC) in light microscopy. We came together in a first on-line Webmeeting on 28th of April, 2020 with about 50 attendees. By now (04/07/2021) the group has grown to 260 people from 24 countries all over the world. We have members from national microscopy communities, companies involved in the microscopy business and organizations or institutions related to standardization on a national or international level (see the graph below and on the member page for an overview).

In the 2nd General Webmeeting on 9th of July, ten working groups were established to bring our common aims quickly forward. These webpages give a short overview about QUAREP-LiMi. In the 3rd General Meeting the working group 11 “Microscopy Publication Standards” was established.

QUAREP-LiMi runs a cloud server with more information and as a common repository and exchange point for our work.

QUAREP-LiMi is absolutely open for new members and we are looking forward to hear from you. If you want to join us fill out the contact form found here. For changing your working group (WG) or joining a new WG use the memberlist on the cloud server or sent an E-Mail to: info@quarep.org or


QUAREP-LiMi has published its first white paper:

QUAREP-LiMi: A community-driven initiative to establish guidelines for quality assessment and reproducibility for instruments and images in light microscopy
