Features
Power and Wavelength in a Single Instrument
The 819-WL optical power and wavelength sensors, when coupled to a 1938-R or 2938-R optical meter, provide the capability to accurately measure the power and wavelength of light sources between 400 and 1100 nm. The sensors are calibrated to NIST traceable power and wavelength standards to ensure accuracy. Simplified mounting, quick setup and alignment, and a two meter cable make the 819-WL sensor easy to integrate into an experiment. The instrument can be integrated with other equipment via USB, RS232, or Ethernet remote interfaces.
Ideal For Laser Diode Testing Applications
The integrating sphere measurement method simplifies optical power measurements of laser diodes and LEDs by eliminating measurement problems related to detector saturation, alignment beam profile, polarization, and back reflection. Since these sensors simultaneously measure wavelength, they have the unique capability to "self-calibrate" the wavelength dependent response of the internal detector. There is no need to enter a reference wavelength for an accurate power measurement; the instrument does it automatically by detecting the signal wavelength.
Thermally Stablized Performance
Each 819-WL optical sensor is temperature controlled via a Thermoelectric Cooler (TEC), with the TEC controller embedded in the electronics enclosure. This offers stable performance in a variety of ambient laboratory temperatures and optical input power levels, with a built-in status LED to ensure optimum accuracy and stability in your measurements.
Custom Specials Available
For volume applications requiring a higher wavelength precision at a trade-off of a smaller wavelength measurement range, please contact your Newport sales representative for our custom specials offerings. For a reduced wavelength range from our standard products, we can provide measurement resolutions as precise as ±0.01 nm.
