Request InfoBristol Instruments Inc.The 438 Series Multi-Wavelength Meter from Bristol Instruments Inc. measures the wavelength, power and optical signal-to-noise ratio of as many as 1000 discrete optical signals. The meter combines Michelson interferometer-based technology with fast Fourier transform analysis. Wavelengths are measured to an accuracy as high as ± 0.3 pm, power is measured to an accuracy of ± 0.5 dB, and optical signal-to-noise ratio is automatically calculated to >40 dB. A measurement rate of 10 Hz enables a reduction in wavelength testing times, resulting in greater manufacturing...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/19/2024Laser Wavelength MetersThe 872A-VIS and 872A-NIR from Bristol Instruments are laser wavelength meters that support laser measurements from 375 to 1700 nm.
