LS-2 LabSource VBG®-Stabilized Dual Laser Source
PD-LD's LS-2 LabSource, a dual-source benchtop module, features two VBG®-stabilized laser sources that are available in standard and custom wavelengths. Unique to other benchtop Raman modules, the LabSource is the only module on the market to offer the combination of 2 laser sources with closely-spaced wavelengths intended for use in Shifted Excitation Raman Difference Spectroscopy (SERDS), a powerful analytical technique which greatly reduces the fluorescence interference in Raman spectroscopy measurements.

PD-LD's LS-2 LabSource module is a VBG®-stabilized dual-laser source, fully-integrated, benchtop module that supports Shifted Excitation Raman Difference Spectroscopy (SERDS). This technology allows greatly improved spectral analysis of compounds that fluoresce or are in the presence of background fluorescence. The LabSource is the only module on the market to offer the combination of 2 laser sources with closely-spaced wavelengths (from 0.1 to about 1 nm) that is the underlying mechanism of SERDS analysis. The difference between the spectral outputs from these two sources enables high-quality spectral data in the presence of background fluorescence.

The LabSource is intended for benchtop applications, where its SERDs capabilities can be integrated with existing laboratory analytical equipment. Due to its small size and ease of setup, it can be used with in multiple setups within a lab.

The LabSource is well-suited to any application in which fluorescence impedes traditional single-source Raman spectroscopy analysis, such as life sciences applications which require analysis of live tissue or organic matter.
