In the field of optical inspection and spectral analysis, Beijing Saifan Optoelectronic Instrument Co., Ltd. has always led the industry development with innovative technologies.
Its independently developed 7IMU10 series single grating scanning monochromator, with its asymmetric horizontal Czerny-Turner optical path design, precise mechanical
transmission system and modular expansion capability, has become a powerful tool for spectral analysis in scientific research and teaching, industrial inspection and high-end manufacturing fields.
Core technology breakthrough: Dual guarantee of optical performance and mechanical precision
The 7IMU10 series monochromator adopts an asymmetric horizontal Czerny-Turner optical path structure. Through aberration avoidance design, it significantly enhances the symmetry of spectral lines.
Combined with a 1200 lines/mm grating (such as the standard configuration of the 7OG1200-500), it achieves wavelength accuracy at 0.5nm and repeatability at 0.25nm. The optical resolution is 30%
higher than that of the traditional design. Its secondary dispersion elimination technology effectively suppresses stray light to the order of 5×10⁻⁴, ensuring the purity of spectral data. The equipment
is equipped with precision ground lead screws and ultra-wear-resistant linear guides, with a minimum step of 0.0625nm. Its mechanical life exceeds 50,000 cycles, and its long-term stability has been
verified by multiple university laboratories.
Flexible expansion: Adaptable to diverse detection scenarios
This series supports RS232/USB dual-mode control and can be seamlessly integrated with the entire series of light sources, detectors and optical fiber interfaces of Saifan Optoelectronics (such as
7IFW6 filter wheel drive module) to build a complete spectral detection system. The equipment offers a wide wavelength coverage from 0 to 1100nm, with a standard slit width of 300μm (adjustable
to 5μm), and is compatible with silicon-based, InGaAs and other detectors, meeting the requirements of the full spectral range from ultraviolet to near-infrared. Its compact design (dimensions
190×150×133mm, weight 3.5kg) and nitrogen filling interface configuration enable it to be deployed in both laboratory benchtop systems and integrated into portable testing equipment.
Application Empowerment: Cross-industry spectral solutions
Research and teaching: The Department of Physics at Tsinghua University has established a quantum efficiency testing platform using the 7IMU10 series, achieving precise measurement of 70%
quantum efficiency of GaN photocathodes at a wavelength of 380nm, thereby facilitating the research and development of semiconductor materials.
Industrial inspection: In the photovoltaic industry, this equipment, in conjunction with the 7-SCSpecIII multi-junction solar cell testing system, completes the spectral response curve analysis of
perovskite cells, providing data support for efficiency optimization.
Environmental monitoring: By being used in conjunction with the 7ILT150 halogen tungsten light source, it can detect the absorption characteristics of organic pollutants in the 200-800nm band
of water bodies, serving the water quality assessment projects of environmental protection departments.
User Witness: Dual recognition of performance and reliability
A C919 large aircraft materials research and development center in Beijing reported: "In the reflectance test of the 7IMU10 series of high-temperature alloy coatings, the wavelength drift after
continuous operation for 72 hours was only 0.1nm, and the data consistency far exceeded that of similar products." In addition, the equipment has passed the ISO9001 quality system certification.
Key components (such as gratings and guide rails) are covered by a three-year warranty, and the after-sales response time is ≤4 hours, demonstrating Saifan Optoelectronics' commitment to quality.
Usher in a new era of precise spectral detection
The 7IMU10 series single grating scanning monochromator from Beijing Saifan Optoelectronics has redefined the performance benchmark of monochromators with its innovative optical design,
breakthroughs in mechanical precision and scenario-based adaptability. Whether it is the cutting-edge exploration of basic research or the quality control of industrial manufacturing, this equipment
will become a reliable partner for researchers and engineers.
