DH-2000-BAL Deuterium-Tungsten Halogen Combined Light Source
The DH-2000-BAL Deuterium-Tungsten Halogen Combined Light Source is the only deuterium-tungsten halogen combined light source in the world that can balance UV-NIR light intensity.; We adopted the recommendations of technical experts regarding the use of dichroic filter technology in light sources and developed the only combined light source that can solve the saturation and signal-to-noise ratio problems associated with the D-alpha line in deuterium lamps.; Features of the DH-2000-BAL Deuterium-Tungsten Halogen Combined Light Source; • Eliminates the D-alpha line of the deuterium lamp;; All deuterium-tungsten light sources produce a D-alpha line, that is, they form jagged peaks in the visible portion of the spectrum, indicating that the deuterium-tungsten halogen light source produces an uneven spectral output. Correcting the spike formed near the wavelength of 655 nm is very difficult. For example, if the user adjusts the spectrometer's integration time to reduce the brightness of the saturated spectral line, it will cause a significant decrease in system efficiency in the UV wavelength range, affecting the signal-to-noise ratio. Likewise, the spectrometer's efficiency is also highest near the wavelength of 655 nm.; Proprietary patented filter technology; The DH-2000-BAL balanced deuterium-tungsten halogen combined light source uses the same high-precision dichroic filter technology as our in-line variable filter, balancing the light intensity of the deuterium-tungsten halogen combined light source, thereby forming a smooth spectrum across the entire band and solving the saturation-related problems. By comparison, it was found that most combined UV-VIR light sources can only adjust relative intensity.; DH-2000-BAL Spectrum; The spectrum of the DH-2000-BAL measured with the HR40000-CG-UV-VIR spectrometer shows: a smooth spectrum is formed across the entire UV-VIS-NIR band, eliminating the D-alpha line.; DH-2000-BAL Specifications
