The NanoGage model 100 short-range position sensor from Optra Inc. has a 3-mm standoff, low sensitivity to electromagnetic interference and a large bandwidth. Suitable for short-range displacement measurements, the aluminum sensor is ~0.5 in. in diameter and 2.2 in. long. It features a linear measurement range of 100 µm, a signal capture range of ±400 µm and 15-nm rms resolution at 100 kHz. It works with reflective surfaces such as glass or metal, with smooth machined surfaces, and it requires a minimum of 4% surface reflectance for a specular target.
