Diffractive Diffuser
We specialize in the production and custom development of high-precision optical diffusers and beam shapers for 3D sensing (ToF), LiDAR, and medical/aesthetic laser systems.
- We have successfully developed diffractive diffusers and broadband flat-top diffusers with high laser-induced damage thresholds (LIDT) for medical/aesthetic lasers and high-power industrial lasers, specifically optimized for 1064nm wavelengths.
- Beyond 1064nm and 532nm, we offer full-spectrum customization for any wavelength and complex beam-profile specification. Whether for specific medical/aesthetic wavelengths—such as 2940nm (Er:YAG) or 755nm (Alexandrite)—or specialized industrial applications ranging from ultraviolet (UV) to deep infrared (IR), our engineering team can design bespoke microlens arrays or multi-level phase structures tailored to the unique characteristics of your light source.
- For 3D sensing and LiDAR applications utilizing VCSEL arrays, we provide high-specification “Polymer-on-Glass” (POG) solutions. Focusing on the core 850nm and 940nm bands, we can engineer highly complex, asymmetric, wide-field-of-view patterns (e.g., 110°×80°, 120°×90°, 120°×50°, etc.) on substrates typically 0.35mm in thickness.
- We can precisely eliminate zero-order hotspots, achieving exceptionally uniform “flat-top” profiles or specific geometric beam shapes, while ensuring absolute stability and clinical safety—even in environments with extremely high LIDT requirements.
Leveraging an industry-leading micro/nano-fabrication platform, we integrate deep customization throughout the entire process, from initial optical design and rapid prototyping to large-scale mass production.
