Kelvin: Optics for smartphones. Focus on What Matters!

This digital project blurs the lines between the convenience of mobile photography and the power of professional optics.

The Levenhuk Kelvin Touch KM7 is an incredibly user-friendly photomicroscope with a touch display and Wi-Fi. Forget about complicated settings. Enjoy intuitive touch controls and comfortable viewing on any device. Examine your samples directly on the 7‑inch touchscreen, connect to a computer, stream the image to an iPhone or Android over Wi‑Fi, or output to a TV. Share your discoveries on social media or host live demonstrations for an entire room. Everyone gets a front-row seat!

The microscope captures stunning 4K photos and records crisp 2K video. Whether you are running a science blog, creating educational films, or putting together a presentation, your content will look spectacular. For maximum convenience, connect via Wi-Fi and control all the shooting settings remotely from the mobile app.

Adjust the magnification by rotating the objectives or using digital zoom – up to 1900x. Begin at low magnification to study the surface of vintage coins, the structure of minerals, or insect shells. Increase the magnification and the fascinating hidden world of microorganisms appears. The precise dual‑stage focusing system locks in perfect sharpness for you at any magnification.

Adjust the illumination for any sample in seconds. Let light pass through transparent specimens or study the surface details of opaque objects. Dual illumination delivers light from above and below, with adjustable brightness. The mechanical stage moves your sample smoothly along two axes, making it easy to pinpoint an area of interest and keep it perfectly framed. It runs on AC power or its built-in battery. A full charge gives you about an hour of cordless operation and takes no more than three hours to recharge.
