Light Guides for Endoscopy
Flexible light guides for precision applications in industry and medical technology.
Light guides that fit your endoscope. Thanks to many years of expertise and experience in fiber optics, combined with consistent quality standards, our flexible light guides are used in a wide range of endoscopes.
Outstanding Light Transmission and Precise Control
Efficient Light Transmission
Our products enable efficient, low-loss light transmission through optimised NA values.
Color-Accurate Imaging
Minimal colour shift: illuminated objects retain their natural colour, even with long light guides.
High Light Collection
Through an optimised numerical aperture (NA), our light guides capture maximum light right at the coupling point.
The Right Numerical Aperture (NA)
for High Image Quality in Endoscopy
The numerical aperture is a critical factor for light capture and the emission angle of light guides. It directly influences the angle (θ) at which light enters or exits the light guide: a higher NA enables a wider capture angle and therefore greater light intake.
Our light guides are available with various NA values to allow optimal adaptation to your endoscopy requirements. Thanks to our manufacturing precision, we achieve high light capture, essential for image quality in your endoscopes.
Maximum Durability & Reliability in use
Beyond optical performance, we place great emphasis on the mechanical and thermal resilience of our light guides.
Autoclavable Systems
For the medical sector, we offer fully sterilisable light guides. High-quality materials ensure compliance with strict hygiene standards and the preservation of light transmission, even after numerous autoclave cycles.
Custom Connector Technology
We manufacture custom end ferrules, connectors and precision components at the micrometre scale. These are matched to your endoscopes and light sources for seamless, loss-free system integration.
