In experiments involving ultraviolet absorption, fluorescence excitation, thin film ultraviolet surface characterization, and trace substance detection, the selection of the light source in the deep ultraviolet band directly determines the baseline noise and detection limit. Many researchers often encounter such problems: short-wavelength ultraviolet energy is weak, and there is insufficient signal near 200nm; the spectrum is discontinuous, and the scanning curve has many burrs; the replacement of the light source is cumbersome, and the optical path debugging takes a long time; the lamp tube has a short lifespan, and frequent replacements increase the experimental cost.

In the 200?400nm ultraviolet range, the deuterium lamp is the standard light source for spectral analysis. The Sevan Optoelectronics 7ILD30 deuterium lamp source is specifically designed for 30W deuterium lamps, capable of outputting deep ultraviolet light as low as 195nm, with outstanding short-wavelength luminance, and significantly better light emission intensity below 360nm compared to halogen tungsten lamps, providing a smooth and continuous ultraviolet spectrum, and is the core unit for building an ultraviolet spectral system.

The built-in long-life deuterium lamp in the light source allows users to quickly replace the lamp tube by themselves without the need for factory disassembly and assembly, reducing the downtime waiting time. When used with the Sevan 7IPD30/7IPD30A deuterium lamp constant current power supply, it can achieve excellent light output stability, with small light intensity drift over a long period of continuous testing, stable baseline, significantly reducing the data dispersion problems in ultraviolet absorption tests and fluorescence excitation experiments, and better repeatability for parallel sample tests.

The optical end adopts a double quartz focusing lens design, with high light output efficiency; it supports the minimum φ3 light spot output, and can flexibly match monochromators, sample chambers, filter wheel sets, PMT detectors, and quickly build a complete spectral testing optical path. The entire machine is cooled by air, with a compact structure, and is easy to install and debug.

It is widely used in universities, research institutes, and enterprise R&D centers, and can be used as an independent ultraviolet light source or fluorescence excitation light source, and is applied in ultraviolet-visible absorption spectroscopy, thin film ultraviolet transmission/reflectance testing, environmental pollutant ultraviolet detection, optical radiation calibration, and ultraviolet quantitative analysis of biological samples, etc.

A domestic research optical solution package, taking into account stability performance, delivery cycle, and after-sales service. The Sevan Optoelectronics 7ILD30 deuterium lamp source provides reliable continuous ultraviolet excitation for deep ultraviolet spectral characterization, reduces system errors caused by the light source, and helps with ultraviolet-related research and material characterization.
