The latest large optical power meters include high-speed, multi-channel, and high-power models from Thorlabs, Newport, Keysight, Ophir, and Dimension, offering advanced measurement, automation, and sensor compatibility.

Thorlabs

Thorlabs offers a wide range of optical power and energy meters, including PM100A, PM100D2, PM100D3, PM400, and PM5020 consoles. These meters support multiple sensor heads with NIST-traceable calibration, allowing users to swap sensors while maintaining accurate measurements. The PM400 console, in particular, can be bundled with popular sensors for convenience. Thorlabs also provides wireless and fiber optic power meters for field applications, with automatic sensor recognition via the red C-series connector for easy integration .

Newport

Newport's latest offerings include the 1936-R/2936-R series, featuring 250 kHz sampling rates and femtowatt-level resolution, making them suitable for highly sensitive measurements. Newport also provides dual-channel benchtop meters, precision fiber optic power meters, and a variety of low-power, laser power, and specialty sensors. Their meters can be extended with additional detectors or software, and virtual optical power meters allow PC-based measurement at lower cost .

Keysight

Keysight's optical power meters are designed for multi-channel measurement and automated test setups, supporting up to eight channels in a compact half-rack form factor. They offer rapid sampling, low latency, and wide dynamic range, with SCPI control for integration into automated systems. Keysight meters use InGaAs sensors for precise, linear, and repeatable measurements across a broad wavelength and power range, suitable for both development and production testing .

Ophir

Ophir's StarBright series is a handheld, feature-rich laser power and energy meter with a bright color display for easy reading. It supports up to eight sensors simultaneously via the StarLab software, and can measure power, single-shot energy, repetitive energy, frequency, beam size, irradiance, and dosage. The StarBright meter is compatible with a wide range of thermal, pyroelectric, and photodiode sensors, and firmware upgrades are straightforward .

Dimension

Dimension's OPM series includes high-performance, high-speed, high-power, and high-sensitivity modules compatible with their ALPHA and OMEGA universal optical test platforms. These modules support one, two, or four detectors per module, with 10 kHz maximum data acquisition speed and 10 million data buffer size per channel. They are designed for automated optical power measurement, fast scanning of passive devices, and integration with other functional test modules for one-stop testing solutions .
