High Precision Wavelength and Power Measurement; Sub-Nanometer Resolution and Accuracy

Gamma Scientific announces the release of the Wavemon™ 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 Wavemon is able to resolve wavelength with accuracies to +/- 0.25 nm and +/- 0.01 nm repeatability and irradiance absolute accuracy of +/- 1%.

The Wavemon 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 rocksolid 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.
