MKS Instruments, Inc., a global provider of enabling technologies that transform our world, has announced the Newport™ 819-SL-06-WL optical power and wavelength sensors at SPIE's Photonics West 2025. These sensors provide accurate, real-time power and wavelength measurements of laser sources between 400 and 1100 nm. Calibrated to NIST traceable standards to ensure accuracy, the 819-WL sensors feature a wide 6 mm aperture that simplifies optical measurements and eliminates problems related to detector saturation, alignment, beam profile, polarization, and back reflection. A convenient way to collect both power and wavelength information from lasers and VCSELs emitters, the 819-WL is designed for use in telecommunications, datacom, 3D sensing, and Lidar applications. When combined with the Newport 1938-R or 2938-R advanced optical meters, the 819-WL sensors provide both benchtop display and remote communication via USB, RS232, or Ethernet interfaces, making them ideal for automated test environments.

The Newport 819-SL-06-WL optical power and wavelength sensors simultaneously measure both power and wavelength, resulting in the unique ability to "self-calibrate" the wavelength dependent response of the internal detector. That means there is no need for the user to enter a reference wavelength in order to obtain an accurate power measurement; the instrument handles this automatically by detecting the laser wavelength. In addition, each sensor includes a thermoelectric cooler for temperature control and a built-in status LED indicator that notifies the user when the device has reached a stable temperature to begin measurements.
"Spectrometers and optical spectrum analyzers tend to be complex and costly ways to take much needed measurements," said Reuven Silverman, General Manager, Ophir Photonics Products. "The 819-SL-06-WL sensors make it easy to collect both power and wavelength from devices under test. The new sensors eliminate many of the problems associated with collecting and sampling light. This helps keep measurements accurate and stable across a variety of ambient laboratory temperatures, signal wavelengths, and optical input power levels."
Simplified mounting, quick setup and alignment, and a two-meter cable make the Newport 819-SL-06-WL sensors easy to integrate into an experiment or manufacturing setup. Both free-space and fiber-coupled input options are available to accommodate a variety of laser systems. For volume applications requiring higher wavelength measurement precision (up to ±0.01 nm), Newport offers customized specials to best meet your product needs.
