A device for optically imaging at least a part of an object, the device having an optical axis and including a two-dimensional first array of first microlenses, having a first side intended to face the object, and a second side, opposite the first side, a two-dimensional second array of second microlenses, each first microlens being aligned with a second microlens on an axis parallel to the optical axis, wherein each first microlens comprises a first catoptric system, and preferably a first catadioptric system.

Multichannel close-up imaging device

The present invention relates to a multichannel imaging device and more specifically to a multichannel device wherein each optical channel has at least an optical low-pass angular filter configured to block any light propagating through the optical channel along a direction of propagation having an angle which is greater than a predefined angle θrelative to the optical axis, the low-pass angular filter comprising at least one planar interface, separating a first material having a first refractive index nand a second material having a second refractive index n, the ratio of the second refractive index over the first refractive index being lower than 1, preferably lower than 0.66.
