New-Focus 125 MHz Photoreceiver
The New-Focus (Newport)1801-FS Silicon Optical Receiver is a free space, 320 to 1000 nm photoreceiver offering a well-balanced combination of gain, bandwidth, and low noise over the DC to 125 MHz frequency range. Because of it's high trans impedance gain and low noise-equivalent power (NEP), it offers the best in sensitivity for signals with rise and fall times as short as 3 ns. This high sensitivity, combined with it's high-level output, reduces the effects of downstream noise sources. For mounting it has a 8-32 mounting thread, and we include an M4 metric adaptor and tool.
