Rochester Precision Optics (RPO) is a leading international manufacturer of aspherical precision optics – in particular customized glass optics ranging in size from 1 mm to 60 mm. It covers a wide range of focal lengths and numerical apertures. This US company took over the proprietary pressing process referred to as precision glass molding (PGM) from Eastman Kodak Company together with the necessary equipment when it was founded in 2005. RPO’s additional strengths include molded plastic optics and CNC-manufactured aspheres for the infrared range. Most of these elements are developed according to customer specifications.
In practice, aspherical lenses offer numerous advantages that reduce the number of optical elements in many applications, which in turn enables more compact and lighter designs.
