High-Precision Wavelength Meter Servo-A10(DP)

Optical Wavelength Range: Min. 1520 nm; Max. 1625 nm Optical Frequency Modulation Repetition Rate: Max. 370 kHz Optical Frequency Deviation [Repetition Rate: 10 kHz]: Max. 560 GHzpp

The A0070A Optical Frequency Analyzer is a revolutionary system for evaluating FMCW LiDAR lasers, capable of observing optical frequency modulation waveforms in real time just like an oscilloscope. By using a unique method, it extracts only the optical frequency modulation component without being affected by optical intensity modulation. No adjustment is required before measurement; the waveform is displayed immediately after laser input. High linearity ensures accurate measurement over a wide optical frequency deviation.;The A0070A accelerates the development and manufacturing of FMCW LiDAR.

Wavelength Range: 1250~1650 nm(182~240 THz) Wavelength Accuracy [1550nm；1550nm)]: ±0.33 ppm(±0.5 pm@1550 nm) Wavelength Repeatability [1550nm；1550nm)]: ±0.07 ppm(+0.1 pm@1550 nm)

As the demand for communication data continues to grow, larger-capacity optical communication transmission systems are required, which drives optical component and network equipment manufacturers to use coherent communication modules based on wavelength-tunable lasers in transmission backbone networks. Currently, the scope of use of wavelength-tunable lasers and coherent modules will further extend down to metropolitan area networks and even access networks. A very important test for tunable lasers is precise measurement and wavelength calibration. As communication channels continue to increase, from the initial 40 channels to the current maximum of 800 channels, fast and accurate wavelength testing is more critical than ever.

Laser wavelength detector: 2048 CMOS detection pixels measure the center wavelength of lasers anywhere from 200 - 1100nm. Integrating-sphere diameters of 25mm, 38mm and 50mm are available. The software tests laser power stability and center-wavelength drift. The figure below shows center-wavelength variation over 10 hours, with a deviation of approximately 0.1nm. Another figure shows that, just after startup, the TEC temperature controller has not reached its ideal state, so intensity is not very stable and optical output power fluctuates slightly.

Yongli CO2 Laser Wavelength Meter: Precision spectral analysis over 9-12μm for researchers and engineers, ensuring wavelength consistency in medicine, marking and specialty-material processing, where absorption and results depend on wavelength. Measurement: Precision diffraction and thermal imaging convert invisible mid-IR into visible data. Each scale division resolves0.02μm, showing shifts under different excitation conditions, standard 10.6μm output and spectral purity. Structure: A precision adjustable base uses three bottom rollers for micrometer alignment. A lifting shutter protects optics during alignment. A clear observation window and simple thermosensitive medium allow direct readings at 9.26μm, 9.54μm or 10.6μm without complex photoelectric conversion. Safety: Power density must remain<40W/cm^2. Instructions emphasize pulse control and attenuation to protect the instrument and maintain professional operating practice. The meter links laboratory theory and industrial use, enabling close understanding of laser-energy properties.
