On our journey to operate more sustainably across our value chain. 🌱🌍
Nicole Ziegler, Head of Sustainability at ZEISS, outlines the company's progress towards its sustainability targets set for 2025.

Sustainability is a core part of our group-wide strategy and is divided into three focus areas: value for society, circular economy and climate action. 🤝 One of our highlights over the past five years, ZEISS has made progress on key goals in these areas. This includes reducing emissions from our own activities (Scope 1 & 2) – something we’re continuing to work on. Over the last five years, we reduced our Scope 1 & 2 CO₂e emissions by 68%. The next step: establishing science-based targets that also address Scope 3 emissions, which are currently under review by the Science Based Targets Initiative (SBTi) to confirm their compliance.

A new step in cancer therapy.

ZEISS Microscopy inside the Optima Pharma manufacturing system gives scientists a clear view into every cell and that clarity helps ensure safer, more effective CAR-T cell therapies for cancer treatment. 🔬

OPTIMA Pharma expert Vilma Methner shares how automated production and continuous imaging improve quality and consistency. Dr. Kathrin Baader Böpple from Bosch Health Campus is convinced of the potential: Instead of chemotherapy for everyone, therapies will increasingly target the individual tumor. Prof. Michael Schmitt from Universitätsklinikum Heidelberg adds a powerful reminder of why this work matters: CAR-T therapy has already given many patients a chance they no longer believed they had.

A partnership of engineering, technology, and medicine: all working toward better cancer care.

What happens when ZEISS employees take their passion for science beyond their daily work? They turn classrooms, cities, and competitions into real-life labs.

Shaping the future of science means inspiring today's youth. Through our "A Heart for Science" initiative, ZEISS employees worldwide volunteer to bring STEM education to life and spark curiosity in the next generation.

Four projects were honored with the "A Heart for Science” Award for their impact, showcasing the variety of enhancing STEM education. 🏆

🇩🇪🇨🇭🇦🇹 GSA Region: Workshops and digital classrooms bring the microcosm into schools, where students discover the microscopic world in a playful way.

🇯🇵 Japan: Children and citizens uncover "invisible" urban ecosystems at the Imperial Palace moat and Meiji Jingu Shrine, using ZEISS microscopes to explore how hidden organisms shape healthier cities.

🇺🇸 US: School groups explore hands-on stations in microscopy, medical technology, X-ray imaging, robotics and sustainability at the ZEISS Innovation Center in California.

🇬🇧 UK: Supporting the FIRST Tech Challenge, mentoring and refereeing student robotics teams to the world championships in Panama.

Today we celebrate World Environmental Education Day 🌍💚

A day that highlights how learning about nature is the first step to protecting it.

At ZEISS, we support projects that help communities grow knowledge – such as initiatives in India where volunteers empower young people to understand their environment and shape a sustainable future. As part of our A Heart for Science (AH4S) initiative, a hands-on STEM workshop was also held on site to inspire young students.

Education builds awareness. Awareness drives change.

Together, we can make a difference. 🌱

Here’s one fact about Ernst Abbe you may not know: As a 19th-century economic liberal, he was opposed to patenting. For this reason, none of his inventions in the field of microscope construction were patented before 1890. 🔬

Like many others, Abbe was convinced by one argument in favor of patenting: The alternative to patenting is secrecy. But secrecy is even more detrimental to progress than the temporary monopoly of a patent. That is why Abbe himself took out patents from 1890 onward, on the condition that these were not allowed to restrict scientific research.

Happy birthday, Ernst Abbe! Thank you for enabling outstanding achievements that have played a decisive role in our company becoming a technological leader. 💙

Have you ever looked at the Earth from the Moon? 🌎👀

A special feature of ZEISS VISUREF 600 is its fixation target: During an eye test, you will see this iconic photo taken in 1968 with a ZEISS lens during the Apollo 8 mission (instead of the typical hot air balloon picture).

New ZEISS VISUREF 600 performs comprehensive eye tests with multiple highly precise measurements in one device. It provides objective refraction data enabling ZEISS premium lens prescriptions and offers functionalities for dry eye screening and soft contact lens fitting.

Happy ! ⛄

We're excited to share an impressive microscopic marvel: a tiny snowman with an even tinier gingerbread house perched on its head.

This whimsical creation, barely visible to the naked eye, demonstrates the incredible precision and potential of nanotechnology. Beyond crafting intricate designs, this work highlights the remarkable possibilities in microscopic innovation.

The image was produced by Travis Casagrande and the Canadian Centre for Electron Microscopy (CCEM) several years ago, using the ZEISS Nvision 40 FIB, which was replaced with a ZEISS Crossbeam 350 LaserFIB. 🔬

Winter magic in the mountains. 🏔️

When snow covers the rocks and transforms the mountains into a snowy landscape, such impressive moments arise. The silence of nature, the clear air, and the gentle crunch of snow underfoot – is there anything more beautiful? ❄️

How does light enable digitalization? 💡📱 80 percent of all microchips manufactured worldwide are produced using optics from ZEISS Semiconductor Manufacturing Technology (SMT). More than 95 percent of chip structures are created with DUV lithography, which can be divided into two different types.

In dry DUV, there is air between the last lens and the wafer instead of liquid. It is primarily used in volume manufacturing and is favored because it allows for cost-effective production and low-maintenance machines. In immersion lithography, a fluid is introduced between the optics and the wafer. The key advantage is that liquids have a higher refractive index than air. This causes the light beam to be deflected more strongly, improving the resolution.

For portrait photographer Jan Düfelsiek, it’s all about real encounters. 📸

In his session with Michelin-starred chef Alina Meissner-Bebrout at Bibraud in Ulm, he captured with ZEISS Camera Lenses her focus, rhythm, and dedication to her craft.
