Overview
Guangyi Intelligent' Biased Photodetectors are available in several models that cover the wavelength range from the UV to the mid-IR (200 nm to 2.6 µm). With a wide bandwidth DC-coupled output, these detectors are ideal for monitoring fast pulsed lasers as well as DC optical sources. The direct photodiode anode current is provided on a side panel SMA. This output is easily converted to a positive voltage using a terminating resistor. When looking at high-speed signals, Guangyi Intelligent recommends using a 50 Ω load resistor. For lower bandwidth applications, our variable terminator or fixed stub-style terminators quickly adjusts the measured voltage. The detectors below do not have amplifiers or built-in gain, which generally allows them to operate at higher speeds than our FPD510 series of amplified photodetectors; for applications that require gain, an amplified photodetector may be more suitable.
