818 Series Calibrated Photodiode Sensors

818 Series Calibrated Photodiode Sensors

NIST traceable 818 Series Photodiode Sensors allow an accurate power measurement over a broad power range with a removable attenuator.

Features

Tightest Calibration Uncertainty

The 818 Series include a full spectral response calibration utilizing NIST-traceable standards calibrated with high-precision equipment maintained in Newport's optical detector calibration facility. Tight calibration facility and process control allows the tightest calibration uncertainty in industry. Each detector is shipped with the calibration data, which is electronically stored inside the detector's EEPROM. A certificate of calibration as well as the actual calibration curves and data with and without the attenuator are shipped with each product. To maintain accuracy and guarantee performance Newport recommends annual photodiode detector calibration.

? NIST traceable calibration with better uncertainty than competition ? Improved 10 mm clear aperture attenuator design ? Detachable calibration module ? Wavelengths from 200?1800 nm ? Removable calibrated OD3 attenuator

Typical spectral responsivity of Newport's low power detectors

The 884-xx Series OD3 attenuators, calibrated for each matching detector and shipped together, extend the calibrated optical dynamic range of our detectors by three decades. Our attenuator design provides high damage threshold and spectral flatness. With the low NEP associated with the photodiodes we are using, a wider dynamic range is achieved. For less than 1 mW input power, we recommend removing the attenuator (0.1 mW for 818-UV/DB between 200 - 400 nm) to maximize the signal to noise ratio.

Newport uses the highest quality semiconductor detector materials available. Available sensor types are silicon (Si), UV-enhanced Si, Germanium, and Indium Gallium Arsenide (InGaAs). Choose 818-UV for 200 - 400 nm wavelength, but note that the maximum measurable power level in 400 1100 nm is as low as 50 mW with the attenuator on. Newport's advanced calibration facility performs the tightest calibrations in the business, further improving the absolute accuracy of our detectors.

Note on Detector Connectors

The models with the /DB suffix come with a detachable BNC/DB15 calibration module that provides direct compatibility with Newport's current power meter offering. The models with the /CM suffix come with a detachable BNC/8-pin mini-DIN calibration module that provides compatibility with legacy Newport power meters. The standard BNC connector allows flexible interfacing with oscilloscopes, lock-in amplifiers or current meters. In both cases, the /CM and /DB adapters contain the detector calibration data, model number, serial number and calibration date for seamless operation with the power meter.

Calibration Module

Order 818-SCAL-OPT when you need to order a calibration module only, for 818 Series photodiode detectors, without recalibration of the detector. When you place an order, inform the sales staff the detector model, the required calibration module type, and its serial number. This part is not orderable online.

1) The limiting factor w/ Attenuator is the damage threshold of the OD3 attenuator. The limiting factor w/o Attanuator is the detector nonlinear response at high input beam intensity. 2) 15 ns pulse width 3) Uniformity specification applies to photodiode only. It does not apply to the attenuator. 4) Calibration uncertainty can be varied depending on the NIST transfer standard uncertainty variation.
