Ross Optical Improves and Expands Micro-Optics Capabilities


Mahr Interferometer at Ross Optical FacilityRoss Optical’s acquisition by Precision Optics Corporation adds new capabilities to our portfolio with micro-optics down to sub-millimeter sizes. Products and systems requiring optical surfaces less than 2 mm in diameter often result in a trade-off, sacrificing either quality, price, or supply.

As a proven optics partner, Precision Optics produces lenses with diameters as small as 0.37 mm using our proprietary micro-precision™ technology. This advanced technology provides customers with products in sizes comparable to GRIN lenses, but with the breadth, capabilities, and quality of precision ground and polished lenses.

In addition, we have a MarOpto FI 1040 Z, a full-featured interferometer that provides non-contact measurements of flat or spherical surfaces and transmitted wavefront of optical components and assemblies. This machine has the following capabilities:

  • 6x zoom for workpieces as small as 0.5 mm in diameter
  • Three modes of interferogram analysis: Phase shifting, IntelliPhase – static spatial carrier analysis, and fringe tracing 
  • F-number from F / 0.7 to F / 6.0


Ross Optical produces micro-lenses with diameters from sub-millimeter to 6.0 mm and ball lenses under a millimeter.  We work with each customer to provide the micro-optics lenses and other components that meet our customer’s unique requirements.

Micro-optics from Ross Optical are at the heart of micro-optical systems, including devices for optical fiber transmission, medical devices, instrumentation and sensing systems, and a host of visualization devices. Micro-optical lenses allow shorter focal lengths for compact systems.
