BNC Terminators
VT1
Variable Terminator
When using a photodiode with a reverse bias, for example when operating in the photoconductive mode, a small photocurrent is produced when the photon is absorbed. Typically, a 50 O resistor is used to maximize the bandwidth. However, it is often desirable to have a higher, easier to measure signal using a larger potential drop when aligning the photodiode. A variable terminator allows the user to set a higher resistance value during beam alignment then lowering the resistance to achieve the best possible bandwidth. This offers a clear advantage over a fixed terminating resistor. Thorlabs offers two terminators, the VT1 variable resistance terminator and the fixed 50 O T4119.
VT1 Variable Terminator offers the user a choice of seven discrete resistance settings which can be easily selected from the outer rotary barrel. The VT1 offers the following values: 50 O, 100 O, 500 O, 1 kO, 5 kO, 10 kO, and 50 kO.
T4119is a 50 O feed-through terminator, which provides the ideal termination needed for our DET series of detectors to achieve maximum bandwidth.
