In scientific research and industrial scenarios such as spectral analysis, optical precision detection, instrument calibration, and material spectral characterization, long-term use of spectrometers and monochromators can lead to wavelength deviations, scale deviations, and scanning accuracy drift. Without regular calibration with a standard light source, it will directly result in misalignment of spectral line identification, distorted experimental data, untraceable detection results, and failure of batch quality control standards. This is one of the core causes of errors in precise spectral experiments. To ensure the long-term high-precision operation of optical instruments and the compliance and traceability of experimental data, it is necessary to rely on official-level standard wavelength calibration light sources.

The 7ILM5 wavelength calibration mercury lamp source from Saifan Optoelectronics is a research-grade standard light source specifically designed for the precise calibration of spectral equipment. It uses imported cold cathode low-pressure mercury lamp cores combined with self-developed high-precision drive systems, outputting multiple sets of standard characteristic spectral lines, covering the core calibration wavelength bands of ultraviolet and visible light. With its core advantages of precise spectral lines, high stability, extremely long lifespan, ready-to-use, and wide adaptability, it becomes the exclusive calibration benchmark for monochromators, spectrometers, and optical testing systems. It is a necessary optical reference device for laboratory metrology calibration, precision calibration in scientific research, and regular equipment maintenance in industrial settings.

Standard characteristic spectral line output, NIST-level precise traceability

The 7ILM5 relies on the unique luminescence characteristics of low-pressure mercury lamps to output multiple discrete, sharp, and free-of-distortion standard characteristic spectral lines. The spectral line positions are precisely fixed and highly recognizable, perfectly matching NIST standard wavelength parameters, without spectral line deviations or band distortions. It can perfectly adapt to the full range of wavelength calibration in the ultraviolet and visible bands, precisely correcting the wavelength scale errors, scanning offsets, and zero-point drifts of spectral equipment, completely solving the problem of precision loss caused by long-term operation of the equipment, making each spectral test data precise, compliant, and traceable, meeting the high-standard precision requirements of universities, metrology testing, and industrial quality inspection.

Cold cathode lamp core technology, high stability and long lifespan

The equipment is equipped with an imported cold cathode low-pressure mercury lamp core as the core of light emission. Different from the shortcomings of traditional hot cathode mercury lamps with high loss, rapid attenuation, and long preheating time, it has advantages such as no impact during startup, stable light emission, extremely low light attenuation, and resistance to aging. The lamp core has extremely strong emission consistency, with no position deviation of spectral lines or significant attenuation of light intensity throughout the entire life cycle. There is no need to frequently calibrate equipment parameters. The ultra-long lifespan design significantly reduces the cost of calibration consumables and the frequency of equipment maintenance, suitable for regular precision calibration in laboratories and regular equipment calibration of industrial production lines.

Highly stable drive output, pure baseline without interference

The accompanying self-developed dedicated constant current drive power supply of Saifan provides extremely low circuit ripple and stable output, completely eliminating spectral line broadening and light intensity fluctuations caused by voltage fluctuations and current drift. During operation, the spectral baseline is straight and pure, the characteristic peaks are sharp and clear, and there are no noise from interference peaks. It can precisely capture the micro-precision deviations of the instrument, adapt to the precise error correction requirements of high-precision spectral equipment, and ensure the instrument is always in the optimal working precision state.

Ready-to-use without preheating, efficient and convenient to operate

The 7ILM5 optimizes the startup circuit logic to achieve rapid ignition, no need for long preheating, and enters the stable calibration state immediately upon startup, eliminating the long waiting process of traditional calibration light sources. The overall integrated design of the equipment is compact, taking up little experimental space, with simple operation and no learning curve, allowing for quick completion of equipment wavelength calibration without professional debugging, significantly improving the efficiency of laboratory instrument maintenance and research experiment progress.
