LS-1

The LS-1 Tungsten Halogen Light Source is a versatile white-light source optimized for the VIS-NIR (360-2500 nm). The lamp offers high color temperature, highly efficient output and long life in a compact, economical package. The LS-1 is available with a 900-hour, 3100 K bulb or a 10,000-hour, 2800 K bulb.

The LS-1 features an SMA 905 Connector for easy coupling to Ocean Optics fiber optic spectrometers and accessories, including optical fibers, cuvette holders and probes.

 

 

LS-1 Features

  • VIS-NIR spectral range (360-2000 nm). Useful for chemical analysis, reflectivity of solid objects and color measurement

  • High color temperature, efficient output

  • Available with color-correcting and signal-attenuating accessories for user-controlled manipulation of light source output.

  • 900-hour or 10,000-hour bulbs

Included with the LS-1 are a 1/2" OD BG-34 filter for color correction and Teflon diffusing disks for attenuation of light source output. The LS-1 comes with a 12 VDC power supply (a European power supply is also available) and a power cord.

The LS-1 is available for $577. Additional LS-1 models are also available.

The LS-1 features an SMA 905 Connector for easy coupling to Ocean Optics fiber optic spectrometers and accessories, including optical fibers, cuvette holders and probes. What's more, a built-in slot accepts loose optical filters up to 3 mm in thickness. Either LS-1 version can be installed with spectrometers and other devices into a multi-device rack unit or desktop box.

Included with the LS-1 are two accessories that may be useful for certain measurements. The 1/2" OD BG-34 filter can be installed into the light source to enhance the signal in the blue region relative to the red and NIR regions (see the first graph below). This filter also has an attenuating effect so that users should adjust spectrometer integration times (by as much as 2-3 times longer) to achieve desired signal amplitude. 

Three Teflon disks of various thickness are also available. These disks are used to create a diffuse source that is optimal for coupling into fibers and attenuating the overall signal when spectrometer saturation is an issue and other attenuation methods (such as adjusting spectrometer integration times) are impractical or undesirable. The disks attenuate approximately 50%, 75% and 99% of the signal, respectively. With a disk installed, the change in lamp output during the warm-up period is slightly more noticeable than without the disk. However, the time to achieve stabilized output (~30 minutes) is unaffected.
