LS-W
LS-W
The document describes the LS-W series of tungsten-halogen light sources, which are powerful and flexible tools for visible to near-infrared (NIR) spectral range applications. These light sources offer adjustable power output, optical fiber connectivity, and remote control capabilities via the SPEC Hub.
The LS-W series includes four models: LS-W7, LS-W14, LS-W20, and LS-W25, each with different power outputs (7W, 14W, 20W, and 25W respectively). The wavelength range for these lamps is 380-3000 nm, except for the LS-W20, which ranges from 300-3000 nm. The lamps have a lifetime of approximately 4000 hours, except for the LS-W20, which lasts around 1500 hours.
- Adjustable Power Output: Users can locally control light intensity using a power output knob.
- Built-in Shutter: Allows for dark measurements without turning off the lamp, enhancing stability and lifespan.
- Filter Slot: Includes a slide filter holder for narrowing the spectral range with various filters.
- Remote Control: Operable via SPEC Hub with TTL compatible signals and intensity control options.
- Optical Fiber Connector: SMA 905 with adjustable focus.
- Cooling System: Air cooling is used to maintain optimal performance.
- Power Requirements: Operates on 24 VDC/2 ADC with a maximum power consumption of 12-30 W depending on the model.
- Dimensions and Weight: The light source measures 200 x 92 x 72 mm and weighs 1.1 kg.
The LS-W light sources are suitable for various applications requiring precise control over light intensity and spectral range, such as reflectance measurements and other spectroscopic analyses.

L S -W TUNGSTEN-HALOGEN LIGHT SOURCE Visible-NIR Spectral Range Adjustable Power Output Optical Fiber Connector Built-in Filter Slot Remote Control with SPEC Hub ADJUST THE LIGHT INTENSITY With W light source you have the possibility of LS-W has an adjustable power output knob to choosing from four different tungsten-halogen locally control the amount of light that reaches your 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 included slide filter holder allows great flexibility, including narrowing the spectral range (by using band-pass, short-pass or long-pass filters) SHUTTER 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 shutting off the lamps, resulting in a more stable and extended lifetime.
