home A digital lock-in radiometery system that has over seven decades of dynamic range without range switching. We developed this from concept through production design. An electric watt-hour meter with daisy-chain communications capability. Used for sub-metering in situations like marinas and apartments. We developed several models from concept through production design. An ultra-high-reliability switchmode power supply that is used on the GPS satellites. A line of industrial-strength infrared thermometers designed to cover a wide range of applications. 36 models were developed from concept through production. A low-cost raster scanner utilizing plastic molded optics. Optical and electronic design were done from concept through production, including molded optics.
