  • Imaging system comprising microlenses and associated device for detecting a sample
    Patent number: 9256008
    Abstract: The invention relates to an imaging system and an associated device for detecting a sample (4). The imaging system comprises a matrix (24) of photosensors (26), a first lamina (28) disposed opposite the matrix (24) of photosensors defining a face (28A) for supporting the sample, and a set (30) of optical elements, disposed between the matrix (24) of photosensors and the first lamina (28). Each microlens (34) is disposed above a photosensor (26) of the matrix (24) of photosensors. The set (30) of optical elements comprises a matrix (32) of microlenses (34). The set (30) of optical elements comprises an optical medium (36) disposed between the matrix (32) of microlenses and the first lamina (28), the refractive index of the optical medium (36) being substantially between 1 and the refractive index of the microlenses (34).
