Fit for all your needs
LS-W is a compact, reliable, and powerful tungsten-halogen light source that meets the demands of most spectroscopic applications covering the visible and near-infrared regions.
Granted flexibility
Including power output controller, SMA connector for optical fiber connection, with adjustable focus, and lamps with different power (7, 14, 20, and 25 watts) provides the W light source with great flexibility and power efficiency.
Key features
A powerful light source
With the W light source, you have the possibility of choosing from four different tungsten-halogen lamps (7, 14, 20, and 25 watts) that range from 300-3000 nm for the 20 watts lamp and 380-3000 nm for the 7, 14, and 25 watts lamps. The optimum power to the optical fiber is achieved through efficient optical coupling and adjustable focus.
Adjustable 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 LS-W provides a simple operation for dark measurements without the need for turning off the light source, 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).
Reflectance Set-up with Reflectance Probe
-
The standard probe holder is a robust and simple-to-use mechanical tool made with black anodized aluminum for securing the probe tip with a fixed distance when measuring the reflectance spectra and color of flat and slightly curved surfaces.
-
Reflectance probes are used to obtain spectral information from fluorescence and reflectance measurements of surfaces and powders.
-
A powerful and flexible spectrometer that fits in the palm of your hand.
