1. Working principle

　　Deuterium halogen lamp light sourceBy integrating deuterium lamp and halogen lamp, wide spectrum output is achieved:

Deuterium lamp: generates ultraviolet spectra by electrically exciting deuterium gas (D ₂), suitable for high-precision analytical instruments.

Halogen lamp: uses tungsten wire to heat up to incandescent state and emit visible light to near-infrared spectrum. Through filtering technology, spectral line burrs can be eliminated, achieving smooth and continuous output.

2. Core advantages

Wide spectrum coverage: Integrating the spectral range of deuterium lamps and halogen lamps to meet the multi band requirements of ultraviolet visible near-infrared.

High stability: ensures long-term measurement accuracy.

Long life design: significantly reduces maintenance costs.

Quick response: The deuterium lamp supports instantaneous switching (without preheating delay), while the halogen lamp has a preheating time of only 20 minutes, suitable for dynamic experimental needs.

2、 Application scenarios
