The Micro Optics That You Need

The growing use of compact, portable, and disposable optical devices challenges suppliers to maintain quality and performance while cutting size, weight, and cost.

Ross Optical's micro optics are not only competitively priced, but also backed by our in-house expertise in design, coating technology, test, inspection, and QA. Our micro optical components include many options available at diameters down to 1 mm:

  • Bi-convex and plano-convex lenses, designed to form and shape light beams
  • Achromat lenses, precision-fabricated to reduce chromatic aberration
  • Ball lenses, used in many types of coupling devices
  • Prisms, shaped to redirect and repurpose light energy
  • Aspheres, shaped to condition light with reduced spacing and parts count
