Digital Gradient Filter

The solution for all stepper and scanner models to prevent UV light from going directly toward the projection lens

Designed for solving important variation in light uniformity and to work under low light intensity, our DGF offers better CD & optical projection uniformity. This cost-effective solution also prevents important stray light effect and better slit uniformity. Furthermore, it’s extended lifetime and short delivery time of 2-3 weeks makes it an obvious choice over OEMs.
