The 818-SL/DB is a silicon photodiode sensor designed for optical power measurement in the 400-1100 nm spectral range, featuring a removable OD3 attenuator and a DB15 calibration module for use with Newport power meters. It has a post-mounted design with a 11.3 mm detector size and a 10.3 mm clear aperture. The sensor offers a maximum measurable power of 2 W with the attenuator and 4 mW without, a calibration uncertainty of 1.65% at 400-430 nm and 1.1% at 430-1000 nm, and a linearity of ±1%. It supports NIST-traceable calibration with ISO 17025 compliance, includes a removable calibration module, and is compatible with fiber-optic adapters for free-space or fiber measurements. The rise time is ≤2 µs, and the minimum measurable power is 20 pW. The sensor operates with a 1.5 m cable and maintains a maximum power density of 30 W/cm² with attenuator and 3 W/cm² without.
The 818-SL/DB Silicon (Si) Photodetector is designed for low optical power measurements and now features a new design with a diffuser for ISO 17025 compliance. It is supplied with a NIST traced calibration report that details individual detector responsivity measured with and without attenuator. Exclusive OD3 attenuator technology extends the calibrated optical dynamic range of our photodiode sensor heads by three decades. The serial numbers for the detector and the attenuator are matched to ensure NIST traceability. The 10.3 mm clear aperture with the cross hair will improve the detector alignment to the input optical beam more accurately and help avoid detector overfilling. This model includes a BNC/DB15 calibration module. The adapter contains the detector calibration data, model number, serial number and calibration date for seamless operation.
