Pakistan (/ËpÃ¦káµ»stÃ¦n/ or /pÉËkáµ»ËstÉËn/; Urdu: Ù¾Ø§Ú©Ø³ØªØ§Ùâ), officially the Islamic Republic of Pakistan, is a federal parliamentary republic in South Asia on the crossroads of Central Asia and Western Asia. It is the sixth-most populous country with a population exceeding 200 million people.
Spectrometers for Laser Measurement. These miniature rugged spectrometers are calibrated to measure and track laser frequency and centroid wavelength and/or total power of lasers in Watts. Currently, StellarNet offers laser measurement systems in the 200-2300nm range.
resolution will be in the range of micrometers, but the maximum range is limited to only a few meters. Up to distances of 100m people often use the phase shift measurement. The laser light is modulated and the phaseshift between outgoing and incoming light gives the distance. To reach a resolution in the millimeter range very high sampling rates are necessary. Only low measuring rates with high current consumtion are possible the consequence. With Time-to-Digital-Converters (TDCâs) you choose the straight way. It is possible to measure directly the time-of-flight of light.
