Light Sources

Optical spectroscopy measurements rely on sources that generate a beam of light with an efficient and stable output. With that in mind, Sarspec offers a number of compact and modular sources for illumination and excitation that can be perfectly combined with each of our spectrometers. Light sources for illumination purposes enable absorbance, transmittance, and reflectance measurements over wavelengths ranging from deep-UV to near-IR. Light sources for excitation purposes generate high-power outputs at specific wavelengths for fluorescence and phosphorescence measurements.

UV-Visible-NIR

Series of modular and reliable sources for illumination and excitation that use deuterium, tungsten halogen and xenon lamps to cover wavelengths ranging from deep UV to near-IR.

LS-DW

DW is a continuous light source that combines the spectrum of deuterium and tungsten halogen lamps into a single optical path, producing a stable output from 185 to 2500 nm. Being low power and high stability DW light source is the best solution for absorption and transmission measurements.

LS-DWHP

DWHP is a continuous light source that combines the spectrum of a powerful deuterium and tungsten halogen lamps into a single optical path, producing a high intensity and stable output from 185 nm to 2500 nm. LS-DWHP is the perfect solution for absorption, transmission, reflectance and irradiance measurements.

LS-XeF

 XeF is a compact pulsed xenon light source that produces a strong output that ranges from 190 to 2000+ nm. XeF light source is the ideal solution for fluorescence and phosphorescence measurements. It can also be used for Absorbance / Tansmittance applications as an high flexibility solution.

Visible-NIR

Series of modular and reliable sources for illumination that use tungsten halogen lamps to cover wavelengths ranging from Visible to near-IR.

LS-W

W is a continuous tungsten halogen light source that provides flexibility while producing a stable and high-power output from 300 to 2500 nm. Available in four versions for different output power and wavelength range, W light source is the perfect solution for absorbance, transmittance, and reflectance measurements.

LED

A compact, modular and stable light source with a narrow band and high-power output that is available in discrete wavelengths ranging from deep UV to near-IR.

LS-LED

LED is an innovative narrow band and high-power light source that produces a continuous, pulsed or modulated spectral output from 265 to 1550 nm. The unique feature of interchangeable LED slides offers extreme flexibility at a low cost, making it the perfect solution for fluorescence and phosphorescence measurements.
