Introducing DeepEn One™ Microendoscopy Platform
Single-Fibre Endoscope for High-Resolution In Vivo Bioimaging
DeepEn One™ is a cutting-edge microendoscopy platform that delivers powerful in vivo bioimaging through a single multimode fibre endoscope (⌀100 µm). It enables researchers to probe deep into the living brain—reaching regions such as the amygdala, VTA, medial septum, brainstem, or spinal cord—while minimizing structural damage and preserving physiological function.

- Depth 5 mm – level of the amygdala
- Field of view: approx. 100 μm × 100 μm

From scientists
for scientists
At DeepEn, we are a team of passionate scientists, engineers, and innovators united by a shared mission: to empower the scientific community with cutting-edge tools that make deep tissue imaging possible and more insightful. Born from years of hands-on research experience, our solutions are designed by scientists who understand the real challenges faced in the lab. We bridge the gap between complex technology and practical application — creating tools that let scientists focus on discovery, not the limitations of their instruments.
About DeepEnNews

In October, DeepEn goes to
Barcelona for Optogen 2026
We are excited to exhibit at OPTOGEN 2026 in Barcelona, Spain, from 12–14 October 2026. The conference brings together leading scientists and technologists working on in vivo optogenetics and optical neural interfaces.
Drop by our booth in the Interior Square at the Barcelona Biomedical Research Park (PRBB), say hello, and discover our ultra-thin microendoscopes. Our team will share insights into the latest technological developments and research applications, and will be happy to discuss how DeepEn One™ can support advanced in vivo neuroscience, optogenetics, and optical neural interface studies.
We look forward to meeting you in Barcelona!
