PD-LD Introduces New LS-1 and LS-2 VBG®-Stabilized Benchtop Modules

January 19, 2012 – PD-LD, Inc. is pleased to formally announce the introduction of the company’s new LabSource series of benchtop laser sources. Two models are currently available. The first, the LS-1, features a single Volume Bragg Grating®-stabilized laser source and the second, the LS-2, features dual laser sources that enable it to perform a variety of unique tasks, e.g., dual wavelength light therapy, specialized analytics, etc.

These modules offer a convenient, customizable solution at a manageable price point. “The modules offer an excellent performance to price ratio and a variety of wavelength options, extending their potential applications beyond spectral analysis,” said PD-LD CEO Vladimir Ban. Both the LS-1 and LS-2 include integrated drive circuitry and software, making them easily integrated with existing laboratory instruments, and with user-friendly interface and ergonomic design, they offer quick set up and ease of use.

“Our design team paid particular attention to the feedback and input received from our customer base and market research in creating this unprecedented instrument” said PD-LD president Uri Abrams. “LabSource has made a quantum leap in design, functionality and the type of user interfaces offered as standard, far surpassing any similar products currently available on the market.” Abrams continued, “ The LS2 model is particularly designed to enable the application of SERDS techniques outlined in our most recent US patent number 7,982,869. We are very optimistic about the near term prospects this new product line offers towards our growth. We already have many units in the market and our operations group is diligently working on fulfilling the growing demand for these units.”

The LS-1 contains a single stabilized laser source, while the LS-2 features two closely-spaced dual laser sources –in lieu of a single source – which enables it to positively identify a far wider range of substances. Most notably, it can analyze and identify fluorescent substances that have previously proven difficult or impossible to identify or analyze via traditional single-source Raman spectroscopy. The underlying dual-source technique, known as Shifted Excitation Raman Differential Spectroscopy, or SERDS, represents a significant development in the capabilities of Raman spectroscopy, particularly in field-based settings or in the analysis of organic and/or biological samples.

The LabSource modules are a major new development in PD-LD’s VBG®-based product line “These modules represent the first completely turnkey VBG®-stabilized products to be offered in the marketplace. They are well-suited for customers who wish to have a complete laser solution, rather than working with a group of discrete parts” said Tom DeBerardine, PD-LD’s VP of marketing and sales.
