Flat Top Diffuser (FTD)
Luminit’s Flat Top Diffuser (FTD) is engineered to transform laser beams into highly uniform flat-top profiles for demanding optical applications. Utilizing a direct-beam laser writing platform and greyscale laser photolithography, we create precision refractive and diffractive optics with feature sizes down to 1 micron—all in a single-step, maskless process.
Our in-house capabilities include design, mastering, replication, testing, and measurement, offering customers a streamlined production pipeline, faster time to market, and a simplified supply chain.
Flat Top Diffusers can be fabricated on thin film or rigid substrates using a variety of scalable manufacturing techniques, including:
- Injection molding
- Roll-to-roll embossing
- Sheet-by-sheet embossing
Production methods are tailored to your substrate, thickness, temperature, and volume requirements.
