Disk drive flat optics:design factors affecting manufacturing and cost in volume

R P Westney et al. Appl Opt. .

Abstract

Polarizers and beam splitters for optical drives are small but expensive. Crystalline, prismatic, or cemented optics can often be replaced with coated flats of comparable performance- Cost drivers are examined, and spectral comparison is made between a plate and cube polarizer. Moisture stability of thin film coatings is discussed, and related applications examined, especially those involving control of the relative phase shift between S and P polarization on reflection. Processes now exist enabling the volume manufacture of these optics.
