Product Description
  • Operating Wavelength: 200-2600 nm
  • Built-in Battery, Low Noise, Fast Response
  • Spatial Type and Fiber Type Available
LBTEK offers Biased Photodetectors covering a wavelength range from ultraviolet to infrared (200-2600 nm), featuring low noise and fast response, capable of meeting the detection needs of various optical signals in different application scenarios. The detectors are equipped with internal bias batteries to provide stable reverse bias voltage. LBTEK fully considers the diverse needs of users by providing two types of detectors: standard and high-speed. The standard detectors output signals via BNC connectors, making them widely suitable for general applications, while the high-speed detectors use SMA connectors to ensure high signal bandwidth, making them more suitable for scenarios with extremely high demands on signal transmission speed and bandwidth. Biased photodetectors can be widely applied in scientific research, optical communications, medical fields, and industrial inspection and other fields.
Biased Photodetectors
  • Operating wavelength covers 200-2600nm
  • Free-space optical input
  • Fastest rise time 1ns
  • Damage threshold: 100mW/cm2
The LBTEK Biased Photodetector series covers three types: Si, InGaAs, and Ge, integrating low noise, fast response, and no gain characteristics, making it suitable for various photodetection applications. With outstanding performance, the fastest rise time is only 1ns, capable of directly receiving free-space input optical signals. The detector has a built-in A23 battery to provide reverse bias. Connect the photodetector's signal interface to downstream acquisition equipment such as oscilloscopes via a BNC-BNC signal cable. Additionally, a red battery monitoring button is installed on the side of the detector, allowing users to quickly determine whether the battery needs replacement with a simple press without removing the battery, significantly improving operational convenience and efficiency.
Note: The product includes an SM1 internal thread sleeve, which can be removed during use.

High-Speed Biased Photodetectors
  • Operating wavelength covers 400-1700nm
  • Free-space input/fiber-coupled input
  • Fastest rise time 100ps
  • Damage threshold: 100mW/cm2

The LBTEK High-speed Biased Photodetector series, covering both Si and InGaAs types, features a wavelength range of 400-1700 nm, integrating low noise, high-speed response, and no-gain characteristics for outstanding performance. In terms of input methods, the LBTEK High-speed Biased Photodetector series offers both free-space and fiber-coupled options to meet the needs of various application scenarios. The fiber-coupled input allows for convenient connection to FC/PC single-mode or multimode fibers, while the free-space input provides two choices: an anti-reflection coated flat window or an uncoated ball lens, offering flexibility for optical signal acquisition in complex environments. The detector has a built-in A23 battery to supply reverse bias. The signal interface of the photodetector can be connected to downstream acquisition devices such as oscilloscopes via a BNC-SMA signal cable.
