Abstract: Optical readers are disclosed in examples herein. An example optical reader including a light source to emit a light beam; and a spot pattern generator to receive the light beam and to generate a two-dimensional spot array from the light beam, the two-dimensional spot array to be directed toward a substrate having nanostructures, the two-dimensional spot array to be sensed to detect a presence or an absence of a substance of interest on the substrate.

Abstract: In one implementation, a spectral microscope may comprise a substrate with a planar lens, the planar lens including a phase profile including an axial focus and an oblique focus, a light source to excite a signal of a particle among a plurality of particles, and a detector to receive light generated from the light source from the axial focus of the planar lens and a spectral color component of the excited signal of the particle from the oblique focus of the planar lens.
