BRISTOL Optical Wavelength Meter and Optical Spectrometer (OSA)

1. Wavelength meters and multi-wavelength meters

The 828A High-Speed Wavelength Meter: real-time measurement rates up to 1kHz, measurement accuracy up to ±0.2ppm for continuous and modulated lasers, and simultaneous measurement of up to 1000 channels. The built-in laser is calibrated in real time, eliminating the need for an external calibration source.

228 Series Wavelength Meters: For single channel light source, signal and device testing.

428, 438 Series Multi-Wavelength Meters: Cost-effective for multi-channel light source, signal and device testing.

2. Optical Spectrometer (OSA)

Product Characteristics

771 Series: General-purpose, high-resolution OSAs with spectral resolution up to 2 GHz and wavelength accuracy up to 1 pm.

750 Series: Fast OSA designed for optical communication, providing efficient spectrum analysis and automatic measurement of Side Mode Suppression Ratio (SMSR) in 0.07 seconds, far exceeding the level of traditional grating OSA.

Specific model comparison is as follows:

These devices are widely used in scenarios such as laser measurement in WDM/DWDM systems, multi-channel signal testing, optical transceiver testing, and laser tuning performance and wavelength stability testing.
