Abstract
A holder and apparatus for terahertz imaging and/or spectroscopy of beads, particles or microparticles, and methods for terahertz imaging and/or spectroscopy of beads, particles or microparticles and making the holder are disclosed. The holder includes a tray having a substantially planar upper surface, and one or more offsets above or below the substantially planar upper surface. Each offset is configured to hold one of the beads, particles or microparticles, and has a height or depth configured to minimize or eliminate interference between reflections of the terahertz radiation from the tray and reflections of the terahertz radiation from the bead, particle or microparticle in or on the offset.
