The LBTEK high-speed biased photodetector series includes Si, InGaAs, and GaAs types, covering a wavelength range of 400-3600 nm. It combines low noise, high-speed response, and no-gain characteristics, offering excellent performance. Regarding input options, the LBTEK high-speed biased photodetector series provides both free-space and fiber-coupled choices to meet different application needs. The fiber-coupled input can easily connect to FC/PC single-mode or multi-mode fibers; the free-space input is available with either an anti-reflection coated flat window or an uncoated spherical lens, providing flexibility for optical signal collection in complex environments. The detector comes with a built-in A23 battery for reverse bias. If you prefer to use a power supply, the power kit (DET-12V) on this product page can be purchased separately. The photodetector’s signal interface can be connected to downstream acquisition equipment, such as an oscilloscope, via a BNC-SMA signal cable.
Note: Other input coupling options can be customized for different models in this series. Please contact LBTEK technical support for details.
