The DET10C/M InGaAs photodetector provides improved bandwidth and NEP performance over previous models. The slim housing allows the optical detector to slip into tight setups. This model comes complete with a fast PIN photodiode and an internal bias battery packaged in a rugged aluminum housing. With a wide bandwidth DC-coupled output, this detector is ideal for monitoring fast pulsed lasers as well as DC optical sources. The DET has a Bias-T circuit that combines a high-frequency AC signal with a DC signal into a single output. The direct photodiode anode current is provided on a side panel BNC. This output is easily converted to a positive voltage using a terminating resistor. When looking at high-speed signals, Thorlabs recommends using a 50 Ohm load resistance. For lower bandwidth applications, our variable terminator is a great time saver.

All connections and controls have been moved away from the light path, thus making the DET a more useful, easier-to-use device. The SM1, SM05, and 8-32 (M4) threadings on the DET detector housing allow it to be mounted in a cage system, lens tube system, or on a TR series post. The DET10C/M arrives with a 12 VDC Bias battery already installed.
