Patent ID: 6930314

Claim:
A light detection device, comprising: a light source configured to produce light of a first wavelength; a wavelength converter configured to receive the light of the first wavelength and to convert that light into light of a second wavelength, where the second wavelength is different than the first wavelength; a system for directing the light of the second wavelength to an examination area, wherein a sample holder comprising a plurality of sample sites is positioned in the examination area; and a detector configured to receive luminescence light from samples positioned in the plurality of sample sites, wherein the system for directing light includes: an optical pattern generator configured to convert the light of the second wavelength into light having a preselected intensity pattern, and an optical relay structure configured to project the light having the preselected pattern onto the examination area, where the projected pattern substantially conforms to the arrangement of sample sites in at least a portion of the sample holder, where the light source is a pulsed laser, where the pulsed laser is triggered by the detector.
