The IR detector, which converts the thermal radiation into electrical signal, is key to performance of many optical/IR systems. To achieve adequate thermal sensitivity and to increase the detectivity of the detector, microlenses should be used to focus the incident radiation onto the sensitive area of the detector. But if we look at the integration compatibility of the double refractive surfaces microlenses in a complete device, we find that they have many drawbacks and the technical achievement of these microlenses seems more difficult in overall technological processes. Fresnel zone plate (FZP) lenses present none of these drawbacks, and their technology is quite compatible with the classical processes which are used for other optical microcomponents. In the present paper, a theoretical analysis and numerical calculations are given to verify the achievements of a proposed thin film FZP in decreasing the diffraction losses, focusing the incident radiation, and hence, enhancing the performance of the detector.
