Our family of silicon detectors comprises calibrated and noncalibrated room temperature and TE stabilized models, in sizes from 0.5 mm diameter to 10 mm2. With the exception of the 71608 and 71648 Detectors, which are used for open air measurements, all are housed in an Oriel flanged enclosure. You can couple these detectors directly to the output of an Oriel Monochromator, or rod mount them to a bench. The housings have a 1.5 Inch Series female flange and a 1/4-20 tapped hole. 0.6 0.4 0.2 0.0 200 400 600 800 1000 1200 TYPICAL RESPONSIVITY (A/W) WAVELENGTH (nm) VIS-IR SILICON UV-ENHANCED SILICON Fig. 1 Typical Responsivity of Silicon Detectors. Calibration We offer calibrated versions of most of these detectors. The standard (VIS-IR) silicon detectors are calibrated from 400 - 1100 nm. The UV detectors are calibrated from 200 -1100 nm. Detectors and Applications Most of the silicon detectors offered here are operated in the photovoltaic (unbiased) mode. The photovoltaic mode of operation offers the lowest noise for DC and low frequency operation, since it avoids the shot noise associated with bias currents. Two units come with standard DC bias arrangements producing 1 ns, and less, rise times. We offer these in 1 mm (model 71894) and 0.5 mm (model 71895) diameters. The low cost detectors, models 71608 and 71648, allow measurements when light tightness, such as provided by the 1.5 Inch Series flange system, is not necessary. TE Cooling Use the room temperature Si detectors for most of your applications. Use the single stage TE cooled/stabilized models when absolute reproducibility of readings is essential, especially when working above 1 ìm. The 77055 Cooler Controller (see page 1242) allows full function of the TE cooled devices. 50Ù Termination Use a 50Ù termination when measuring 100 ns pulse widths or 10 MHz modulated signals. This will eliminate reflected electrical signal echoes from spoiling the fidelity of your measurements. Amplification Detectors are available with and without a built-in transimpedance amplifier. The table gives the gain/bandwidth information for the transimpedance amplifier. The amplifier provides transimpedance gains from 104 V/A to 109 V/A. It also offers three selectable time constant settings to allow you to match the upper bandwidth limit with your experimental needs. Operating at the lowest bandwidth setting allows you to operate at the lowest noise levels. The amplified models require +/-15 V DC; the 70703 Power Supply (described on page 1247) provides the required power. Table 1 Bandwidth Values Time Constant Gain 104 V/A 105 V/A 106 V/A 107 V/A 108 V/A 109 V/A "MIN" 100 kHz* 100 kHz* 80 kHz 8 kHz 800 Hz 80 Hz "MED" 100 kHz 10 kHz 1 kHz 100 Hz 10 Hz 1 Hz "MAX" 1 kHz 100 Hz 10 Hz 1 Hz 0.1 Hz 0.01 Hz * The bandwidth is inversely proportional to gain only up to the limiting bandwidth of the amplifier. There may be a lower system limit due to the detector or other electronic element. • Areas to 10 mm2 • Bandwidths DC to 400 MHz • Room temperature and stabilized models • Models with spectral calibration
