Femtowatt (ultra low noise min. NEP 0.7fW/√Hz), variable gain (10E3 to 10E11 V/W) and fixed gain photoreceivers offer a solution to measuring fast and precise small optical signals. By combining a low noise transimpedance amplifier with a silicon or InGaAs photodiode a broad wavelength range from 190nm up to 1700nm is covered. Ideal for all lab scenarios, fibre alignment, fast power monitoring, testing laser diodes, linearity measurements over 10 decades, and industrial control and aligment are just a few applications.
