In basic research and teaching scenarios such as spectral teaching experiments, routine photometric calibration, material optical testing, and light source spectral analysis, equipment is bulky and cumbersome, the operation is cumbersome, the cost performance is low, and the basic accuracy is insufficient. These are common pain points for most laboratories. Many routine spectral experiments do not require ultra-high-specification dual-grating equipment, but they need a compact, easy-to-adjust, sufficient-precision, stable, and highly compatible standardized spectrometric device that can balance experimental accuracy and teaching practicality.

The Sefan Optoelectronics 7IMS10 series single-grating scanning monochromator is a compact high-precision spectrometric equipment specifically designed for basic research, university teaching, and routine industrial detection. Relying on a mature asymmetric C-T optical architecture, precise sine drive structure, and intelligent electronic control system, with a lightweight body, standardized spectrometric accuracy, extremely low operation and maintenance costs, it perfectly adapts to most routine spectral experiment scenarios, becoming the standard equipment for university physical optics teaching, photonic laboratories, and high-performance cost-effective main equipment for small and medium-sized enterprises' quality inspection.

The 7IMS10 series supports manual knob adjustment + computer automatic control dual operation modes, suitable for different usage scenarios: manual mode is intuitive and clear in operation, suitable for university teaching demonstrations and student practical exercises, with a very low learning threshold; computer mode can complete continuous wavelength scanning, fixed-point wavelength locking, and grating parameter calibration with one click, with high automation, suitable for precise experimental scenarios such as project research, data collection, and batch detection.

It is equipped with two standard USB and RS232 communication interfaces, plug-and-play, stable transmission, compatible with various computer terminals, and can be quickly set up without complex debugging. It can flexibly switch between spectral scanning speed and test wavelength band, fully covering the conventional spectral range of ultraviolet, visible, and near-infrared, balancing experimental efficiency and test accuracy.

Lightweight integrated design, high versatility and expandability, quickly set up experimental system

Unlike the cumbersome and space-consuming drawbacks of traditional large-scale spectroscopic equipment, the 7IMS10 series adopts a compact integrated body design, featuring small size, easy installation, and no occupation of experimental space. It is suitable for small optical platforms, teaching experimental tables, and integrated online detection equipment. The equipment has extremely strong scalability, with the light entry port seamlessly connecting to the entire series of xenon light sources and steady-state light sources of Sifan, and the light exit port compatible with various fiber optic interfaces, photodetectors, and optical testing fixtures.

Without complex modifications, it can quickly build a standardized integrated spectroscopy testing system with light source, dispersion, and detection, meeting the upgrade needs of various scenarios in experiments, taking into account both current teaching use and future research expansion. The equipment utilization rate is far higher than that of ordinary simple monochromators.
