Coher Sense

ICORS 2026 kicked off yesterday evening. We have our founder Oliver, and chief of science Katarzyna on site in Istanbul. Not giving a talk this time, but looking for your feedback on our latest developments presenting a poster this afternoon. Swing by #537. #Raman

Proof that the Coher Sense team is always working… even when working involves a pre-flight beverage at Schipol airport around 10am. 😉 Safe travels to Oliver as he heads for Istanbul to ICORS! We can’twait to hear how the community picks up the poster presentation. #Raman #Lasers #NotNoodles #ICORS #10MHz

Last week Oliver traded the boss hat for the lab rat outfit. 🐀🧑🔬🌈 Sometimes the best place for a founder isn't behind a desk, but in front of an optical setup, spending the entire day measuring, questioning, and learning. A huge thank you to Dominik S. and Christian Scholz at LTB Lasertechnik Berlin GmbH for opening their facility to us and making one of their DEMON 2 Double Echelle ultra-high-resolution spectrometers available for testing our latest optical concepts. Our current KISA sensors already achieve around 1 pm (≈1 GHz) wavelength resolution. But one customer challenge pushed us far beyond the capabilities of our own measurement infrastructure. That was the moment we knew it was time to ask for help. The question was ambitious: Can we improve by another three orders of magnitude while preserving everything that makes KISA... KISA? Compact. Low power. Low cost. Environmentally stable. We often say that measuring lasers should become simpler. Ironically, making it simpler requires understanding them at an entirely new level first. As engineers, we're trained to solve problems ourselves. But sometimes the smartest engineering decision is knowing when someone else has exactly the tool you need. Luckily, our friends at LTB said yes. Last Thursday wasn't just another measurement day. It reminded us why we enjoy working in photonics so much. People share ideas. People share equipment. People genuinely want each other to succeed. One lesson worth remembering: Build your network before you need it. Be kind. Help others. And never be afraid to ask. The photonics community continues to amaze us with its openness, expertise, and collaborative spirit, and we are incredibly grateful to be part of it. Our latest concept is still just that—a concept. But thanks to days like last Thursday, it's one step closer to becoming a product. Science advances through measurements. Innovation advances through people. Thank you, LTB. We truly appreciate your support. #Photonics #Quantum #LaserTechnology #Innovation #Collaboration #KISA

What a day at Physikalisch-Technische Bundesanstalt, PTB Berlin! 🚀 When you get the chance to test your hardware at Germany’s national metrology institute, you don't hesitate. To be honest, we were absolutely thrilled to just be considered for this—and incredibly excited to "mess with the best." (And let’s be real, we stood our ground... barely! 😉) A massive thank you to Anne and Victor for opening up your labs today and putting our KISA sensors to the ultimate test. Your hospitality, expertise, and unmatched testing environment made for an unforgettable visit. While we are still diving deep into the data, the initial results have left us incredibly proud: - Exceeding Expectations: The electronics designed by our student, Till Jensen , performed phenomenally. It looks like our official specs might actually be quite conservative! - The Core Focus: While we didn't test every single feature KISA has to offer, we thoroughly vetted our most sought-after capability—and the potential is thrilling. - Keeping Us Grounded: The extensive testing also highlighted areas where we still have work to do. We welcome these insights; they are exactly what we need to keep pushing the boundaries of our technology. A quick visit turned into an afternoon marathon... 🕒 Word apparently spread fast that the AMA Association for Sensors and Measurement Innovation Award and Hamamatsu Photonics Europe Photonics Innovation Award winner was in the house! What was meant to be a standard demo turned into a fantastic four-hour extension as curious minds from around other departments stopped by to talk shop, ask questions, and share ideas. It’s safe to say we left feeling incredibly inspired. 📸 Take a look at the photos below to see: Our KISA sensor installed and working hard in PTB's optical setups (configurable for both fiber-coupled as in the image or free-space use). A few shots from the stunning, historic PTB hall. Thank you again to everyone at PTB Berlin who made the day so productive and welcoming. The hard work continues! #Photonics #DeepTech #SensorTechnology #Innovation #PTBBerlin #Metrology #CoherSense #Optics #EngineeringExcellence

Final and third day of SENSOR+TEST is kicking off. Swing by to get a glimpse at our AMA Association for Sensors and Measurement Innovation Award winning tech or swing by for calibration of your light saber. Check out how compact laser sensing can support applications from laser research, industrial gas sensing all the way up to quantum computers. Oliver Lischtschenko and Katarzyna Szykuła-Meurs are looking forward to exchanging thoughts with you on your application. You can find us at booth number 1-143. Just follow the path to the dark side - we have Knoppers. ;)

Kicking off sensor and test day 2. Following day 1 with winning the AMA innovation award, this show started with a bang for us. If you’re interested in learning about our innovative (and prizewinning) KISA sensor technology can help you stabilize your lasers in real world applications like gas sensing, optical strain measurement, humidity detection or even fluorescence based measurements, feel free to swing by our booth 1–143 and have a chat with our CSO Katarzyna Szykuła-Meurs or our CEO Oliver Lischtschenko. Also, check out the cool NIR laser sensor demo at 1550nm we created with the help of our friends at RGB Lasersystems GmbH and their tiny lasers. We are looking forward to seeing you. Huge shout out to the FabLab Lübeck e. V. for supporting us with the little 3D-printed iconic Holstein Gates. People love picking them up as goodies and it’s always very often a good memory they share about visiting the city.

The car is ready and off we go to SENSOR+TEST in Nuremberg. Long march ahead and then tomorrow afternoon setting up the booth. Come swing by 1–143 starting Tuesday after the opening ceremony around 10:30. Our CSO Katarzyna and CEO Oliver are looking forward to understanding your challenges with #lasers in real life. Oh, and of course, don’t forget to keep your fingers crossed for our nomination at the AMA Association for Sensors and Measurement innovation awards Tuesday morning.

✨ Coher Sense is officially introducing NIR KISA at SENSOR+TEST 2026 We are excited to announce that we will officially introduce our NIR KISA laser diagnostics system at SENSOR+TEST 2026 in Nuremberg. With NIR KISA, we are extending our compact laser diagnostics platform into the 900–2600 nm range, enabling simultaneous insight into wavelength, power, and drift behavior for modern laser systems. Whether you work in laser development, OEM integration, production testing, spectroscopy, telecom, or quantum technologies, we would be happy to show you what compact, scalable laser diagnostics can look like. 📍 SENSOR+TEST 2026 📅 9–11 June 2026 📌 Nuremberg, Germany 🔎 Booth 1-143 We are also proud that Coher Sense has been nominated for the AMA Innovation Award 2026, presented by the AMA Association for Sensors and Measurement — a great recognition for our work on making laser diagnostics more compact, scalable and integration-ready. Come by, see the NIR KISA live and let’s talk about your laser diagnostics challenge. 🎟️ We share a link for free trade show tickets in the comments. #SensorTest2026 #AMAInnovationAward #Photonics #LaserDiagnostics #NIR #Spectroscopy #LaserTechnology #Optics #MeasurementTechnology
