LS-W

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.

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.

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.

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).

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.
