HP-250 Series Fiber Spectrometers, featuring a high-speed STM320 processor with FreeRTOS system and a high-precision linear CCD optical sensor with 3648 pixel resolution, are developed based on the principle of long-focus cross asymmetric CT spectroscopic system. They are designed for their lightweight, stable performance, high accuracy, cost-effectiveness, and portability, and come with PC software. They challenge the traditional concepts of large, complex, and expensive high-precision spectrometers. They can sample and measure various spectral data energies, and with the PC software, they can efficiently analyze and process test data, offering superior measurement linearity and accuracy. They are widely used in universities, laboratories, homes, shopping malls, schools, factories, greenhouses, outdoor, and on-site lighting measurement fields. They are also used in the research and development of light source products and production line quality control. They have also received positive feedback in the eyewear and jewelry industries. They can perform energy analysis on the transmittance, absorbance, and reflectance of objects and liquids. They are widely applicable in the fields of petrochemical and basic organic chemical industries, polymer chemistry, pharmaceuticals and clinical applications, biochemical industries, environmental sciences, textile industries, and food industries.
