[摘要]：Digital web cameras (popularly known as webcams) have recently gained a significant increase of relevance in the field of optical microscopy, in particular to allow for quick and do-it-yourself methods in developing low-cost and portable microscopes suitable for life sciences and engineering applications in low-resource areas. Unfortunately, these methods were published without any systematic explanation and quantitative assessment of the imaging performances. We reproduce these do-it-yourself methods, discuss the optical considerations that are relevant for them, and quantitatively compare their imaging performances to a commercial digital microscope in order to clarify both the advantages and disadvantages of the webcam-based microscopes.
