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 our first online Web meeting on 28th of April, 2020 with about 50 attendees. By now (16th of November 2022) the group has grown to 465 people from 34 countries all over the world. We have members from national microscopy communities, companies involved in the microscopy business, organizations or institutions related to standardization on a national or international level, and scientific publishers and observers from funding agencies (see the graph below and on the member page for an overview).

In the 2nd General Web meeting on the 9th of July 2020, ten working groups were established to bring our common aims quickly forward. These web pages give a short overview of QUAREP-LiMi. In the 3rd General Meeting working group 11 “Microscopy Publication Standards” was established and later we established working group 12 “Image Visualization and Analysis“.

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 hearing from you. If you want to join the initiative, fill out our form. Use our form for changing your working group (WG) or joining a new WG. For any further questions please contact us.

QUAREP-LiMi now requires a Specialist Support Officer to assist with a number of critical tasks associated with maintaining, promoting and growing a large international and diverse community of scientists and industry participants.

You should have an understanding of microscopy, data management, research funding and publishing but opportunities for training and self-directed learning will be provided. You will be expected to take the lead on a number of specific administrative, promotional and technical tasks which require a scientific background.  These will include but are not limited to: maintaining the large and ever growing list of participants, their affiliations and WorkGroup (WG) assignments; supporting meetings; developing and maintaining the QUAREP-LiMi website and databases, social media streams, community outreach and conference organising.

The WG 1 released its first protocol “Illumination Power and Illumination Stability“. The protocol is featured on

Beside step-by-step instructions, the protocol provides:

Today, December 3, 2021, a special edition of Nature Methods was published containing an amazing selection of publications aimed at improving the quality of research results based on light microscopic techniques. The edition contains proposals, requests and demands from researchers for the development and establishment of new quality standards, software tools and techniques for recording, documenting and storing microscope images.
