A fit for all your needs
A powerful light source
With W light source you have the possibility of choosing from four different tungsten-halogen lamps (7, 14, 20, and 25 watts) that range from 300-2500 nm for the 20 watts lamp and 380-2500 nm for the 7, 14, and 25 watts lamps. The optimum power to the optical fiber is achieved through an efficient optical coupling and adjustable focus.
Adjust the light intensity
LS-W has an adjustable power output knob to locally control the amount of light that reaches your sample. And with 4 different lamps with 7, 14, 20, and 25 watts you can always get the amount of light you need.
Shutter control for maximum performance
The built-in shutter controller included on the W light source provides a simple operation for dark measurements without the need for turning off the lamps, resulting in a more stable and extended lifetime.
Select the ideal spectral range
LS-W has a built-in filter slot. The filter holder that fits in this slot can accommodate one 12.7 mm filter and allows great flexibility, including narrowing the spectral range (by using band-pass, short-pass or long-pass filters).

Tungsten-Halogen Light Source
LS-W is a powerful Vis-NIR source that exceeds the demands for absorbance, transmittance and reflectance measurements. The continuous spectrum provided by the tungsten-halogen lamp is stable and offers high efficiency for a wide range of educational, scientific, and industrial spectroscopic applications.
