Luminit utilizes a direct-beam laser writing platform and proven manufacturing processes to bring flat top diffusers into high volume production. Our greyscale laser photolithography is a single-step, maskless writing process that enables the creation or mastering of refractive and diffractive optics with feature sizes down to 1 micron. With design, mastering, replication, test and measurement under one roof, advantages for customers include faster time to market and simplified supply chains. Thin film or rigid optical components can be manufactured by injection molding, roll-to-roll embossing, or sheet-by-sheet embossing, depending on thickness, substrate, temperature and volume requirements.
