An optical-microwave-quantum transducer can include a first nanophotonic slab and a second nanophotonic slab. Each luminaire is selectively operable to emit source light, characterized by a dominant source light wavelength within a range from 390 nanometers to 750 nanometers. Through controlling the convex or concave shape of the surfaces andor the refracting power of the lens elements, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened. The mechanism further includes a cap having an exit port to seal the open first end of the reservoir. The apparatus includes logic to activate the second sensor when the first sensor transitions from the active mode to the dormant mode.
