Photoreceivers

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.

Ultra-Fast Photorecievers Series HSA-X-S

Ultra-fast photoreceivers for measurements up to 2 GHz

Photoreceivers

Combining state of the art photodiodes with proven and outstanding FEMTO GHz amplifier technology a new family of photoreceivers with a remarkable performance has been designed. The HSA-X-S offers an upper bandwidth limit of 2 GHz. Two models with either a fast Si or InGaAs photodiode cover a spectral range from 320 to 1000 nm and 850 to 1700 nm, respectively. Due to the sophisticated amplifier design the minimum NEP is just 14 pW/√Hz at a transimpedance of 5 x 10^3 V/A. This allows for the measurement of optical power levels in the µW range with GHz speed. For the HSA-X-S-1G4-SI with silicon photodiode the effective active diameter is a remarkably large 0.8 mm due to the use of a ball lens in front of the detector chip.

Applications include spectroscopy, fast pulse measurements, optical triggering.
