New Focus, a Newport Corp. brand, has introduced the GHz Nirvana, a high-speed photo-receiver with automatic signal balancing that provides high bandwidth and fiber coupling. The patent-pending autobalance feature eliminates background noise from dynamically changing systems, including thermal drift and wavelength dependence, yielding perfect power balance between the reference and signal beams. It also eliminates the need to optically balance the detectors and enables measurement systems that can accommodate drift over time. The user also can balance in optical and manual modes. The autobalance feature and variable gain increase the receiver's flexibility and ease of use, enabling the user to adjust the detector instead of having to adjust components such as the optics, lasers and samples used in an application.
