Engineered diffusers are optical diffusers that have better control over the homogeneity and divergence angles than a normal or conventional diffuser. Thus, making an engineered diffuser involves a design stage in which the characteristics of the desired output beam are considered and play an important role. We can distinguish two types of engineered diffusers: the broadband diffuser and the diffractive diffuser. The first type of engineered diffuser is very efficient across many different wavelengths. This […]
