Ultra-Low-Noise Balanced Photodetector UBD-500M-A
The ultralow-noise balanced photodetector has approximately one-third the noise floor of a conventional balanced detector and suits applications with stricter noise requirements. • InGaAs balanced photodetector: 800-1700nm. • Si balanced photodetector: 400~1100nm. Product introduction: The UBD ultralow-noise balanced detector module is an upgrade of the MBD series. With other parameters unchanged, it provides markedly lower background noise. At the same bandwidth and gain, noise is approximately one-third that of MBD, yielding higher sensitivity and signal-to-noise ratio. InGaAs detector responsivity curve.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
