Measure up to 16 layers in coex film.
The noncontacting infrared (IR) sensor is mounted on a ring circling the bubble and contains both a transmitter and receiver. It can use either of two wavelengths--830 nanometers (near-IR) or 1300 nm (between NIR and IR)--to take up to 4000 measurements a second Rapid refocusing gives it a working range of 2 to 22 mm, allowing it to measure even a rapidly fluttering bubble, Isis says. The minimum layer thickness it can measure is 5 microns. Absolute accuracy on smooth film is said to be [+ or -] 0.25 microns. Tel: +49 (621) 842 510 * www.isis-optronics.com
