In the field of optical inspection, Beijing SOFN Instrument Co., LTD., relying on its profound technical accumulation and innovative strength, has launched the 7IMS30
series single grating scanning monochromator. This device, with its outstanding optical performance, precise mechanical structure and wide range of application
scenarios, has become an ideal tool for spectral analysis in scientific research, teaching and industrial inspection fields.
Core technology: Dual breakthroughs in optics and mechanics
The 7IMS30 series single grating scanning monochromator adopts an asymmetric horizontal Czerny-Turner optical path design, combined with aberration elimination
technology, significantly enhancing the symmetry of spectral lines and optical resolution. Its secondary dispersion elimination design effectively reduces stray light and
ensures the purity of spectral data. The device is equipped with a 1200-line/mm grating (such as the standard configuration of 7OG1200-500), with a wide scanning
wavelength range of 0-1100nm, covering the application range of silicon detectors, and an optical resolution of 0.1nm.
In terms of mechanical structure, the 7IMS30 series is equipped with precision ground lead screws and ultra-wear-resistant linear guides, ensuring long-term stability
and spectral accuracy during operation. The minimum step distance can reach 0.00625nm (using a 1200g/mm grating), achieving high-precision wavelength scanning.
In addition, the optical chamber of the equipment is strictly isolated from the mechanical transmission chamber to prevent the contamination of optical components
by stray light and the evaporation of lubricating oil.
Flexible configuration: Adaptable to diverse detection requirements
The 7IMS30 series supports RS232 interface, which can be connected to a computer to achieve automatic control and is convenient to be integrated into an automated
testing system. The equipment can be configured with various gratings and detectors to adapt to different wavelength ranges and application requirements. For instance,
by replacing gratings with different line pairs (such as 7OG600-500, 7OG300-500, etc.), users can flexibly adjust the spectral resolution and wavelength coverage range.
In addition, the 7IMS30 series is also equipped with a scanning knob indicator, which supports manual wavelength setting and is easy to operate. The inlet of the equipment
can be connected to various light sources and optical fiber interfaces of SOFN Instruments, and the outlet can be connected to single-point detectors, linear array/area array
detectors, and even a CCD can be installed for use as a spectrometer, meeting diverse demands ranging from simple spectral measurement to complex spectral imaging.
Application scenarios: Comprehensive coverage of scientific research and industry
The 7IMS30 series single grating scanning monochromator is widely used in scientific research and teaching, industrial inspection, environmental monitoring and other fields
Research and teaching: In fields such as physics, chemistry, and materials science, the equipment can be used for experiments like spectral analysis, fluorescence measurement,
and Raman spectroscopy. For instance, the Department of Physics at Tsinghua University has established a quantum efficiency testing platform using the 7IMS30 series,
achieving precise measurement of 70% quantum efficiency of GaN photocathodes at a wavelength of 380nm.
Industrial inspection: In fields such as semiconductor manufacturing, photovoltaic industry, and optical films, the equipment can be used for material quality inspection, film
thickness control, spectral response testing, etc. For instance, the solar cell spectral response testing system of Saifan Optoelectronics, based on the 7IMS30 series
monochromator, provides a complete spectral response testing solution for various types of solar cells.
Environmental monitoring: The equipment can be used for spectral analysis of environmental samples such as water quality analysis and air pollution detection. By connecting
optical fibers and detectors, remote and online monitoring can be achieved, facilitating research in the field of environmental protection.

Since its launch, the 7IMS30 series single grating scanning monochromator has received unanimous praise from users. The user believes that the equipment performs
outstandingly in terms of optical performance, mechanical accuracy, and operational convenience. Especially in terms of long-term operational stability, the equipment has
withstood the rigorous tests of scientific research and industrial sites, becoming a trusted testing tool for users.
Market positioning: A cost-effective choice for the mid-to-high-end market
The 7IMS30 series single grating scanning monochromator is positioned in the mid-to-high-end market, meeting the strict demands of scientific research and industrial fields
for spectral analysis with high performance, high precision and high stability. The price range of the equipment is from 5,000 to 10,000 yuan, and it has a relatively high cost
performance compared with similar products. Meanwhile, Saifan Optoelectronics offers comprehensive after-sales service and technical support to ensure that users have
no worries during the usage process.
