Oriel's family of photdiode sensors come with a standard 1.5 Inch Series flange allowing instant connectivity to other Oriel instruments, such as monochromator exit slit assemblies. A 1/4-20 tapped hole can be used for rod or surface mounting. They are offered in standard and calibrated versions for use with Newport optical power meters as well as room temperature and TE stabilized versions. Our InGaAs and Ge photodiode sensors cover the spectal information rich 0.7 to 2.5 µm NIR measurements. These sensors are operated in the photovoltaic (unbiased) mode to provide the lowest noise for DC and low frequency operation since it avoids the shot noise associated with bias currents. One unit, model 71898 , comes with a DC bias arrangement producing 1 ns rise times. We offer amplified and unamplified versions. Their large areas make signal capture easy. Use the Ge detectors to get beyond the 1.6 µm limit of standard InGaAs. Our Silicon photodiode sensors are offered in sizes from 0.5 mm diameter to 10 mm<sup>2</sup>. With the exception of the 71608 and 71648 photodiode sensors, which are used for open air measurements, all are housed in an Oriel flanged enclosure.

Calibration

We offer calibrated and standard phodiode sensors. The calibrated InGaAs detectors come with NIST traceable calibrated responsivity factors for the 0.8 to 1.7 µm range. The Germanium detectors NIST traceable calibrated responsivity factors cover the 0.7 to 1.8 µm range. The standard (VIS-IR) silicon detectors are calibrated from 400 -1100 nm. The UV detectors are calibrated from 200 -1100 nm.

Amplification

Detectors are available with and without a built-in transimpedance amplifier. Table 1 gives the gain/bandwidth information for the built-in 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 or 70709 Power Supply provides the required power. 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.

Cooled or Room Temperature?

You will do well with room temperature Si, InGaAs and Ge devices under most measurement conditions. Both are quite stable. However, the responsivity of the diodes is sensitive to temperature changes. It can go up or down with temperature, depending on the spectral range in which you operate. Therefore, whenever you are looking for measurement reproducibility of better than ~2%, temperature stabilization becomes a necessity. Our TE cooled devices, combined with the 77055 Temperature Controller, give you excellent stability of readings. The added benefit of TE cooling is the reduction of noise levels which allows you to reach the limits of device performance.

50Ω Termination

Use a 50Ω termination when measuring ≤100 ns pulse widths or ≥10 MHz modulated signals to avoid electronic echoes generated by signal reflections at impedance mismatch locations.

Electronic Accesories

The 77055 Cooler Controller allows full function of the TE cooled devices. The 70703 or 70709 Power Supply provides the required ±15 V for the amplifiers.

Connectors and Cables

All detectors have a BNC connector for signal out. We ship these detectors with a 6 ft. (1.8 m) long BNC cable; the amplified models also include a 6 ft. (1.8 m) long cable with 3 pin banana plug, for connection to the 70703 / 70709 Power Supply.

Mounting

The flanged detectors are enclosed in aluminum housings with a 1/4-20 tapped hole in the bottom for rod mounting, and a 1.5 Inch Series female flange for direct coupling to Oriel Monochromators.
