Applications of SCHOTT® Luminous Laser Diffusers
Laser diffusers are suitable for light-based medical treatments, supporting the medical industry’s fight against cancer. In other fields, dermatology procedures benefit from the use of highly precise and effective laser delivery, while dentists use lasers to destroy the bacteria that causes gum disease.
PDT / PIT light delivery
Next-generation cancer treatments are based on uniform light delivery in narrow access paths, typically for intracavitary applications including illumination of hollow organs such as the bladder or other anatomical cavities. These treatments use light to activate photosensitizers and help therapeutic compounds reach cancerous cells. That is why photo dynamic and photoimmuno therapy device concepts (PDT/PIT) often require defined emission lengths and high axial homogeneity to achieve consistent illumination across the target zone. SCHOTT® Luminous Diffusers support side‑emitting and tip‑emitting geometries, with configurations tailored to wavelength, emission length, and device architecture requirements.
LITT light delivery
In laser‑induced thermal therapy (LITT) device concepts for neurological applications such as epilepsy and brain tumor treatments, optical fibers or interstitial laser diffusers are used to deliver controlled laser energy into targeted brain tissue. Important is the support of highly homogeneous light emission and efficient transmission at near‑infrared wavelengths, enabling predictable energy delivery within minimally invasive probe architectures.
aPDT light delivery
In antimicrobial photodynamic therapy (aPDT) device concepts used in dental applications or gum treatment, light is delivered locally to activate photosensitive agents for antimicrobial treatment, for example in inflamed gingival tissue. SCHOTT® Luminous Diffusers support controlled and homogeneous light delivery in compact fiber‑based probe designs, with configurations tailored to visible wavelengths and defined emission geometries. Their reproducible optical performance and configurable geometries support integration into dental devices requiring precise, localized illumination.
Surface or planar illumination
Front‑emitting diffuser designs can be configured to broaden and shape the output at the distal tip for defined illumination areas, as needed for external light-based therapies such as skin treatments. Optical components can be combined with the fiber to support uniform surface light delivery as well as specific beam shapes or intensity distributions in dermatological device designs.
High‑power NIR light delivery
SCHOTT® Luminous Diffusers are designed for efficient transmission at visible and near‑infrared wavelengths up to 2,000 nm, supporting device architectures that require stable optical performance and low heat emissions at higher power levels, used in endovenous laser therapy (EVLT) for the treatment of varicose veins.
