LGR includes more than 12,000 square feet of R&D space located in the center of Silicon Valley, in Mountain View, California. These facilities, which may be divided into several laboratories and centers, include the state-of-the-art optical, electronic and mechanical infrastructure that allows our scientists and engineers to develop, test and manufacture leading-edge products for our customers.

R&D Laser Laboratory
The Laser Laboratory is equipped with various continuous-wave and pulsed lasers (including diode lasers, quantum cascade lasers, cw and pulse dye lasers) operating at wavelengths ranging from the UV to the mid-infrared spectral regions, high-resolution wavemeters and interferometers, telecommunications grade fiber-optic components, as well as optical tables, several clean rooms and clean benches, and computational facilities.

R&D Microfluidics Laboratory
The Microfluidics Laboratory consists of our MEMS and chemical analysis facilities and includes multiple wet chemical instrumentation as well as a suite of inspection stations, microscopes and micro-manipulators. This Lab provides 300 square feet of clean room capability housing high-magnification inspection stations and spin-coating stations. The Lab also features several high-resolution micro-positioners and view scopes. The ongoing work at LGR in microfluidics is supplemented by our access to the Stanford University Nanofab Facility, which offers qualified uses access to some of the most sophisticated fabrication equipment available anywhere.

Product Development Center
The Product Development Center allows our engineers to transfer the novel ideas from the R&D lab into real products. In this Center, our engineers and scientists develop and test new devices ranging from comprehensive gas sensing instrumentation and cavity ringdown products to accessories that extend the utility of our Gas Analyzers and OEM product line. In addition to internally developed products, the wide capabilities of the Product Development Center allow us to also specialize in custom instrumentation. If you are looking for new specific sensor systems or products based upon our cavity enhanced absorption (ICOS and CRD) or laser spectroscopy in general, please contact us at sales@lgrinc.com

Manufacturing Center
The Manufacturing Center includes the infrastructure necessary to fabricate and extensively test our full product line of instrumentation and components. Containing more than several thousand square feet of space, the center includes a fully equipped machine shop, environmental test facilities (thermal and humidity chambers), mechanical test facilities (vibration and shaker tables), electronics shop, and computational test facilities.
