In the field of high-end spectroscopy analysis, the ultimate balance of wavelength coverage, resolution, stray light and stability has always been the core pursuit of scientific research and industrial detection. The 7ISU50 series of three-grating scanning monochromators from Saifan Optoelectronics, with a 500mm long focal length, intelligent collaboration of three gratings and precise mechanical control, creates a "full-spectrum coverage, ultra-high resolution, ultimate purity, stable and reliable" flagship-level solution, becoming the preferred tool for cutting-edge research, high-end manufacturing and optical metrology, and redefining the benchmark of high-end monochromators' performance.

The core breakthrough of the 7ISU50 series lies in the perfect integration of the 500mm asymmetric horizontal Czerny-Turner optical path and the three-grating system. It is standardly equipped with three gratings of 1200 lines/mm, 600 lines/mm and 300 lines/mm, with wavelength coverage ranging from 185 to 1250nm, covering the entire range from deep ultraviolet to near-infrared. The software can switch bands with one click, without the need for manual replacement of gratings and recalibration. The aberration cancellation and secondary dispersion cancellation design makes the spectral lines more symmetrical, with stray light as low as 5×10⁻⁴, and the data purity far exceeds industry standards. The F/8 optical system combined with precise gratings has a resolution of 0.03nm, a minimum step accuracy of 0.0023nm, full wavelength repeatability and accuracy, and can easily distinguish nanometer-level wavelength differences, meeting the requirements of Raman, fluorescence, absorption and other high-precision measurement needs.

In terms of mechanical and control aspects, the 7ISU50 series showcases meticulous craftsmanship. Precise worm gear transmission ensures smooth operation, low noise and long lifespan, completely eliminating errors caused by mechanical jitter. The optical chamber and mechanical chamber are strictly separated to prevent lubricating oil from contaminating optical components, ensuring long-term operational stability. The slit is continuously adjustable from 10μm to 3mm, with automatic protection of the blade edge, balancing precision and durability. USB high-speed communication supports computer automatic control of grating switching, wavelength scanning and filter replacement, plug-and-play, and one-click completion of wide-spectrum testing. Beijing Saifan Optoelectronics Instrument Co., Ltd. Exclusive nitrogen gas filling port eliminates atmospheric absorption interference, making ultraviolet and near-infrared measurements more accurate.

From basic research to high-end manufacturing, the 7ISU50 series has no boundaries of application. In research laboratories, it is the core for optical characterization of quantum dots, perovskites and two-dimensional materials, helping semiconductor, new energy and new material research to break through, becoming the "data foundation" of frontier research. In the industrial field, it is embedded in production lines for photovoltaic spectral response, film thickness and composition detection, LED wavelength calibration, achieving second-second-second output of precise results within seconds, improving product quality and production efficiency. In optical metrology and environmental monitoring, it accurately captures weak signals, supporting light source calibration, gas component analysis and trace substance detection, providing reliable support for scientific research decisions and environmental monitoring.

Compatible with SMA905 optical fiber interface, various light sources and single-point/line array/planar array detectors, the 7ISU50 series can quickly build customized testing systems, adapting to multiple scenarios and diverse needs. Whether it is basic experiments in university laboratories or harsh conditions in industrial production lines, it provides stable output and efficient operation, becoming the "efficient assistant" for researchers and engineers.

Choosing the 7ISU50 series is choosing "all-round, precise, stable" high-end spectroscopy solutions. It breaks through import dependence with hard-core technology and empowers domestic research and industrial upgrading with high cost-effectiveness, ensuring each spectroscopic measurement is ultra-pure and each set of data is accurate and reliable. On the path of exploring light and matter, the 7ISU50 series always crafts precision with meticulous craftsmanship and empowers innovation with professionalism, becoming your best partner to unlock the truth of spectroscopy and break through the boundaries of research.
