Design of Refractive/Diffractive Hybrid Projection Lens for DMD-Based Maskless Lithography
The projection lens is the core component of DMD-based maskless lithography and its imaging quality directly affects the transferal of exposure pattern. Based on the traditional projection lens system, we have designed diffractive optical element (DOE) and aspheric surfaces to optimize the refractiv...
