VIS Lamps
Modern analytical instruments require light sources that support the performance of the instrument. VIS/tungsten halogen lamps (also known as tungsten lamps) and other light sources are available. Not only are they designed for long life, but they also ensure maximum precision and stability. Choose between Agilent Technologies or our own quality brand Altmann Analytik. You will always get the optimal lamp for your instrument.

Tungsten-Halogen Lamps for Laboratory Applications
Tungsten-halogen lamps (also referred to as tungsten lamps) are used in laboratories either individually or in combination with a deuterium lamp to optimize the spectral emission of analytical instruments in the visible wavelength range. Depending on the design and operating conditions, the power output ranges from 5 W to 200 W, while the service life—also influenced by operating conditions—varies between approximately 50 and 2,000 hours.
Inside the lamp, there is a very fine tungsten filament. When an electric current is applied, the filament heats up to temperatures exceeding 2,500 to 3,000 °C and begins to glow. Due to its extremely high melting point, tungsten is particularly heat-resistant and durable. In addition, it produces a continuous emission spectrum, which is essential for precise spectroscopic measurements.
In laboratory settings, tungsten lamps therefore serve as stable light sources in the visible and near-infrared spectral range and are primarily used in spectroscopy and other optical analytical methods.
