SCHOTT® Luminous Laser Diffusers
SCHOTT® Luminous Laser Fiber Diffusers are glass-based optical fiber diffusers for internal and external light-based therapies. They deliver homogeneous light distribution and uniform irradiance via cylindrical, spherical (360°), or front-emitting geometries. Integrable into catheter, endoscopic, and probe-based systems, they support minimally invasive, intracavitary, and surface treatments with high optical efficiency across visible and NIR wavelengths for PDT, PIT, and LITT applications.
High homogeneity and light radiation efficiency
Advanced light‑based medical devices require consistent and predictable illumination. SCHOTT® Luminous Diffusers achieve high radiation homogeneity and optical efficiency, supporting reliable light delivery across defined emission geometries. Extensive internal testing of our diffusers demonstrates highly homogeneous light emission and optical efficiencies of more than 80%, with reproducible results depending on diffuser configuration.
Full range of service capabilities
SCHOTT supports customers throughout the entire development process: from early‑stage design and prototyping through application engineering, customization, and high‑volume serial production. Our expertise includes micro‑assembly of complex light guides and medical‑grade surface treatments and coatings. This end-to-end support helps OEMs develop custom laser light delivery systems, laser light delivery components, and tailored diffuser solutions for specific therapeutic, geometric, or integration requirements.
Setting new standards for laser delivery
Achieving extremely homogeneous radiation characteristics together with high power, high efficiency, and broad wavelength compatibility is a key requirement in modern medical laser delivery. SCHOTT® Luminous Diffusers combine these properties in a durable glass-based platform developed from SCHOTT’s long-standing expertise in glass processing and light transport through glass. Whether used as a laser fiber diffuser, fiber optic diffuser, spherical diffuser tip, or front-emitting optical diffuser, SCHOTT solutions are designed to support reliable performance in demanding medical environments where uniform light output, miniaturized dimensions, and tailored beam characteristics are critical.
High homogeneity
Uniform radiation characteristics optimize performance in demanding applications.
High optical efficiency
More than 80 % of laser light is transferred.
High power
Throughput of up to 20 W is supported.
Low heat emissions
A high level of temperature resistance means heat emissions are kept to a minimum.
