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 accessories and spectrometers. Light sources for illumination purposes enable absorbance, transmittance, and reflectance measurements ranging from deep-UV to near-IR. Light sources for excitation purposes generate high-power outputs ranging from deep-UV to near-IR for fluorescence measurements.

UV-Vis-NIR

Series of modular and reliable sources for continuous 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 LS-DW is the best solution for absorbance and transmittance 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 absorbance, transmittance, and reflectance measurements.

LS-XeF

XeF is a compact pulsed xenon light source that produces a strong output that ranges from 190 to around 2000 nm. LS-XeF is the ideal solution for fluorescence measurements. It can also be used for absorbance and transmittance measurements as a high-flexibility solution.

Vis-NIR

Series of modular and reliable sources for continuous 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 ranges, LS-W 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 ranging from 265 to 1550 nm. It features the interchangeable LED slide, which offers extreme flexibility at a low cost, making it the perfect solution for fluorescence measurements.

UniLight

UniLight is a complete solution for a large sample and high-performance irradiation with a great efficiency and uniformity. 

Unilight

The LED irradiation board spectral output is user-customizable and ranges from 265 to 1550 nm. It features a Controller Box for local and remote control with the Light Controller software.
