918D-SL-OD2R In Stock

The 918D-SL-OD2R by Newport is an Optical Power Detector, designed for precise optical power measurements. Engineered around a silicon photodiode, this detector has a spectral range spanning from 400 nm to 1100 nm. This photodiode enables accurate measurements ranging from milli-Watts to femto-Watts. For applications needing a broad power range, the device incorporates a built-in attenuator, extending its capability to encompass the 200 mW to 10 W range. Designed for low optical power applications, the 918D-SL-OD2R incorporates integrated data storage and a built-in OD2 attenuator filter, complete with an electronic attenuator on/off sensor. This sensor possesses the capacity to detect electronic signals for temperature drift compensation, enhancing measurement accuracy amidst temperature fluctuations.

The strategic design of the 918D-SL-OD2R's attenuator ensures exceptional spectral flatness and a resilient damage threshold. The integrated photodiode boasts a low Noise Equivalent Power (NEP), effectively widening the attainable dynamic measurement range. To optimize the signal-to-noise ratio for input powers below 1 mW, it is advisable to deactivate the attenuator. Seamless compatibility with DB15 based power meters characterizes the 918D-SL-OD2R. When connected to a power meter, the detector seamlessly adjusts its responsivity value, obviating the need for manual recalibration of the power meter setup. It's important to note that while calibration is aligned with the integrated attenuator, data remains stored in the EEPROM even when the attenuator is removed.
