We describe the use of microlenses as amplification for CCD-based detection devices. The possible amplification of a signal in areaction chamber of a nanoplate is estimated with a first-order approximation. This value was proved with a commercially available microlens and with a specially constructed microlens array made of glass hemispheres. Possible applications of this approach to amplification are given.
