The SuperCam is a next-generation scientific instrument that examines rocks and soils with a camera, laser, and spectrometers to seek organic compounds that could be related to past life on Mars. It can identify the chemical and mineral makeup of targets as small as a pencil point from a distance of more than 20 feet (7 meters).

Today’s automobiles provide a prime example. In a single vehicle, you can find Wi-Fi, Bluetooth, satellite radio, GPS systems, LED lights, air conditioning, power steering, anti-lock brakes, rear-view cameras, and other instrumentation. Numerous items also operate using dc motors, including power seats, adjustable mirrors, windshield wipers, power windows, and sunroofs. This same example could also apply to items ranging from Wi-Fi or Bluetooth-enabled appliances like washing machines, espresso machines, medical instruments, and even medical implants.

A compact and cost-effective NIR-VIS-UV lidar echo emulator (LEE) was designed and manufactured as a compact breadboard. The LEE is an application-specific optical pulse shaper delivering a short lidar return (echo) in the ns range overlapped with a long lidar return in the µs range with a repetition rate from 100 Hz – 500 Hz. The short echo power levels are in the range from 0.2–200 nW, whereas the long echo powers are from 0.1–25 pW.

Tantalum nitride-based precision thin-film resistors are impervious to corrosion caused by moisture because they are self-passivating. The RTAN series from Stackpole is a tantalum nitride thin film chip resistor that withstands biased humidity testing at 85oC, 85% relative humidity, ten per cent rated power with very little resistance shift
