In conventional spectral teaching experiments, basic spectral detection, small monochromators operation, and daily calibration of photonic equipment scenarios, most laboratories commonly encounter problems such as bulky calibration equipment, cumbersome operation, long preheating time, poor stability, and high maintenance costs. When spectral instruments are in long-term scanning operation, slight wavelength drift, scale shift, and spectral line misalignment are inevitable. Without regular and precise calibration, it will directly lead to deviations in basic experimental data, poor repeatability, distorted teaching demonstration effects, and inability to meet the standardized precision requirements of routine research and teaching.

The Sefan Optoelectronics 7ILM3A mercury light source is an integrated portable wavelength calibration light source specifically designed for basic spectral calibration scenarios. It adopts a core design of cold cathode low-pressure mercury lamp and power supply integration, with five core advantages of ultra-high stability, standard characteristic spectral lines, extremely long service life, plug-and-play, and portability. This simplifies the spectral calibration process, accurately corrects instrument wavelength errors, and becomes a standard-level calibration device for university teaching laboratories, basic optical detection, and small spectral system operation.

Standard discrete spectral lines, accurately complete wavelength traceability calibration

The 7ILM3A relies on the mature light emission mechanism of the cold cathode low-pressure mercury lamp, outputting multiple sets of standard discrete characteristic spectral lines in the ultraviolet-visible wavelength range. The spectral lines are sharp and clear, without peaks or spectral line broadening, with fixed and precise wavelength positions, fully matching the standard spectral parameters. It can efficiently complete wavelength calibration, zero-point drift correction, and scan accuracy reset for monochromators, small spectrometers, and optical scanning systems, accurately solving the problems of wavelength drift and data inaccuracy caused by long-term use of conventional instruments, making basic spectral experiments, teaching demonstrations, and data consistent, reliable, and traceable, and improving the efficiency of laboratory instrument maintenance and experimental implementation.

Integrated integration minimalist design, plug-and-play without debugging

Different from the traditional structure shortcomings of separate lamp sources and power supplies, complicated wiring, and complex debugging, the 7ILM3A adopts a lamp source and power supply integrated structure. The entire machine is compact and lightweight, not occupying the limited space of the optical platform. It truly realizes plug-and-play, without complex wiring, no professional optical path adjustment, no long-term preheating, and can output stable standard spectral lines upon startup, greatly reducing the threshold of spectral calibration, suitable for frequent calibration and rapid equipment operation scenarios, and significantly improving the efficiency of laboratory instrument maintenance and experimental implementation.

High energy stable spectrum output, no fluctuations during long-term calibration

The equipment optimizes the light emission circuit and drive architecture, ensuring sufficient spectral output energy, uniform and stable light emission, completely avoiding problems such as light intensity fluctuations, output jitter, and spectral line drift of ordinary calibration light sources. The entire machine operates stably, with a pure baseline, extremely high peak identification, and no light intensity fluctuations or spectral line shifts during long-term continuous calibration, capable of stably supporting multiple sets of equipment for continuous calibration and batch experimental calibration operations, ensuring consistent calibration results and precise error correction every time.

Cold cathode filament support, ultra-long service life and low maintenance cost

Equipped with high-performance cold cathode low-pressure mercury filament, compared with traditional hot cathode mercury lamps, it has outstanding advantages such as no current impact during startup, extremely low light decay, anti-aging, and resistance to high-frequency start-stop. During the entire service life of the equipment, the spectral line accuracy is stable, the light intensity decay is weak, and there is no need to frequently replace consumables, significantly reducing the maintenance cost and frequency of calibration equipment in laboratories. The durable and reliable hardware quality perfectly adapts to regular university teaching, long-term high-frequency use in laboratories, and industrial basic detection calibration conditions.

Wide compatibility, compatible with all series of conventional spectral equipment

The 7ILM3A has extremely strong versatility and compatibility, can seamlessly match Sefan's entire series of 7IMS grating monochromators and conventional scanning spectrometers, and is also compatible with mainstream small-scale spectral detection equipment and teaching optical instruments on the market. The standardized light output structure has smooth optical path coupling and no loss of connection, suitable for various optical platform construction needs, and can quickly complete equipment accuracy calibration, fault reset, and daily calibration maintenance, making it a highly versatile basic spectral calibration equipment.

Universal scene adaptation, suitable for both teaching and research

With its core features of portability, stability, ease of use, and high cost-effectiveness, it is widely applicable to various scenarios such as university physics spectroscopy teaching experiments, basic research spectral accuracy calibration, operation and maintenance of small photodetection equipment, basic testing of optical components, and regular metrological calibration of laboratory instruments. It can not only meet the intuitive and stable requirements of teaching demonstrations, but also support the accuracy calibration standards of routine research experiments. It is an indispensable calibration reference equipment for basic optical laboratories.
