ShenZhen Hoyatek Co.,Ltd. was established in 2005, dedicated to the development and production of light source test equipment. Its products are widely used in the fields of optical communication, interferometry, and optical fiber sensor testing. It is recognized as a manufacturer dedicated to optical applications. ShenZhen Hoyatek Co.,Ltd. introduced the world's advanced technology in 2017, deeply studied the analysis of laser beam quality 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

Measuring principle

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

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

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

n 700nm-3μm: Maximum 25W for pyroelectric detectors; 1W maximum for germanium detectors.

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