NIRVANA PHOTORECEIVER ALLOWS SHOT-NOISE-LIMITED DETECTION

New Focus introduces the first commercial DC auto-balancing photoreceiver. Traditional balanced photoreceivers, which require the user to manually balance the power in a reference and signal arm, can be difficult to use. The Nirvana auto- balancing photoreceiver solves this problem by electronically balancing the photocurrents from the signal and reference photodiodes. These photoreceivers provide greater than 50-dB noise suppression even at frequencies of less than 100 kHz. Their sensitivity and ease-of-use make them ideal for applications which require highly sensitive shot-noise-limited measurments. These auto-balancing photoreceivers are especially useful for spectroscopy, biomedical applications, and electro-optic sampling.
