Butterfly-Package Balanced Photodetector DBD-2G-A
Butterfly-packaged balanced photodetectors offer small size, low weight and low power consumption for module and system integration. Options include InGaAs balanced photodetectors (800-2400nm) and Si balanced photodetectors (400~1100nm). The butterfly-packaged balanced detector integrates two matched ultralow-noise analog PIN detectors and a low-noise broadband transimpedance amplifier, powered by a single supply. It reduces common-mode signal noise and improves system signal-to-noise ratio. While retaining the original module performance, its compact, lightweight, low-power design is particularly suited to module and system integration. InGaAs butterfly balanced photodetectors are also specified at 800~1700nm.

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.
