October 11, 2019 – San Diego, CA – Gamma Scientific announces the release of the LambdaMeter wavelength and power meter. The unit delivers accurate, real-time wavelength data combined with power measurement at a fraction of the cost of traditional spectrometers. Using proprietary optical filtering techniques and onboard calibration data, the LambdaMeter is able to resolve wavelength with accuracies to +/- 0.25 nm and +/- 0.01 nm repeatability and irradiance absolute accuracy of +/- 1%.

The LambdaMeter is particularly well-suited for wavelength and power measurement of traditional laser sources, VCSEL devices, and LED’s.  Real-time monochromator wavelength monitoring is also readily achievable.  Ideal for test and characterization, the product is compatible with continuous-wave and pulsed sources from 365 nm to 1,100 nm, with short-wave infrared options.

High dynamic range is achieved using a transimpedance amplifier with 5 gain ranges, and rock-solid stability via temperature stabilized detectors and optical filters. The compact unit is particularly well suited for laboratory and production environments and comes standard with a USB 2.0 interface and drivers for Windows®, macOS, and Linux.  Calibration per ISO 17025 accreditation is also available.

For over 50 years, Gamma Scientific has delivered highly innovative, state-of-the-art and award-winning measurement solutions for manufacturers and users of light sources, sensors and displays.  Products include high precision spectroradiometers, calibration light sources, goniophotometers, integrating spheres, thin film measurement systems, and LED testers and sorters.  The company also operates an ISO/IEC 17025, NVLAP accredited laboratory (NVLAP Laboratory code 200823-0) for calibration and testing.
