Shenzhen Haoyuan Optoelectronics Technology Co., Ltd. introduced the world's advanced technology in 2017, conducted in-depth research on laser beam quality analysis and energy distribution, and launched the HY series BPS-GE-0103 beam quality analysis system based on the actual production needs of domestic manufacturers.

HY-BPS-GE-0103 Series---Beam Analyzer System

Measurement principle

Two orthogonal slits pass the beam in front of a photodetector. The beam passing through the slit strikes the detector, causing a current to be generated. The signal generated by the detector is linearly proportional to the irradiance of the beam passing through the slit. A digital encoder can accurately measure the slit position. The current signal generated by photoluminescence is converted into a digital signal and analyzed, and finally the beam profile of the X-axis and Y-axis is obtained. The slit is equivalent to a physical attenuator, which can prevent the beam applied to the detector from being too strong and saturating the detector.

The power that BPS-GE-0103 can measure depends on the wavelength of the laser being measured. The wavelength determines not only the reflectivity at the slit surface but also the energy interaction with the material. Generally speaking, the following three basic wavelength ranges illustrate the power range that a probe can measure.

n 3μm-FIR (>20μm): pyroelectric detector maximum 100W.

n 700nm-3μm: pyroelectric detector maximum 25W; germanium detector maximum 1W.

n 190-700mn: pyroelectric detector maximum 3W; silicon detector maximum 1W
