SPIDER PHOTODETECTOR
Broadband. Amplified. ADC embedded.
Much more than a Photodetector
Unique in its class, our SPIDER Photodetector (Single-PIxel DEtectoR) is an amplified Si-InGaAs photodetector with programmable gain and an embedded 24bit data acquisition system. The employed two-color detector provides a straightforward beam alignment and a wide spectral response, ranging from 320nm to 1700nm.

Modes of operation
SPIDER Photodetector has been designed to work either standalone or connected to a PC.
Standalone
The amplified analog signals coming from the Si and InGaAs channels can be directly read with two BNC connectors.
The gain for both channels can be easily selected by pressing the proper button on the back of the device, and reading the corresponding settings on the built-in OLED display.
Connected to a PC
When SPIDER Photodetector is connected to a computer via USB, it can be fully controlled by a customizable user interface based on a user-friendly DLL.
Thanks to the embedded 24bit data acquisition system, the Si and InGaAs analog outputs are simultaneously digitalized up to 120 kSPS – 24bit and sent to the computer to be visualized in real time.
SPIDER Photodetector also includes 3 GPIO pins (general purpose input output) which can be used to generate or read digital signals. This allows the SPIDER Photodetector to control simple external device (e.g. shutter open/closed) and read a start/stop acquisition signal (e.g. external trigger).

It goes great with…
The SPIDER Photodetector can be naturally coupled with the GEMINI Interferometer, to obtain a 320-1700 nm Spectrometer.
Fluorescent Lamp Spectrum, measured with GEMINI Interferometer + SPIDER Photodetector.
The spectrum is the result of a single measurement, and it covers 3 octaves without any high order artifacts, which would be found if using a grating-based spectrometer.
