Uv/Vis and NIR Spectrophotometry Systems
You purchase laboratory equipment with aspirations of successful experiments, valuable publications, and no downtime. We agree. Using expertise developed since the 1960s, we design, computerize, and produce workhorse UV/Vis and NIR spectrophotometry systems that return best results with fewest opportunities for error and waste.
For our first twenty years in business, researchers worldwide came to us to computerize and improve spectrophotometers they already owned. Laboratories large and small continue to choose to upcycle their trusted HP 8453, Cary 14, Cary 17, and PerkinElmer 983 spectrometers with us.
Since 1994, we have hand-crafted hundreds of all-new Olis products which will likewise stand the test of time for optical excellence. Designed-in upgradability, best-in-class performance, and your best results define our philosophy.
Circularly Polarized Luminescence
For researchers interested in circularly polarized luminescence, the OLIS CPL Solo the only commercial small and affordable model available. It offers highest sensitivity and precision in measuring chiral emissive molecules yielding valuable insights into molecular structure and interactions. Models for UV/Vis, Vis/NIR, NIR, and IR are available.
Phosphorescence lifetime
Phosphorescence lifetime measurements are available in a free-standing system as well as add as an optional enhancement to the fluorescence and CPL models.
Chiral studies of ground and excited state molecules are supported for characterization of molecular chirality, providing valuable information about molecular structure and interactions.

CLARiTY UV/Vis
OLIS CLARiTY is a line of UV/Vis spectrophotometers for measuring pathlength correctable absorbance on light scattering (turbid/ hazy) samples as well as clear.
CD UV/Vis
CD spectroscopy is used to study the chirality of molecules. OLIS produces CD spectrophotometers for deepest UV through NIR spectral ranges, all employing an entirely digital data acquisition method which can only result in the correct answer.
Reflectance, Diffuse & Specular
Diffuse and specular reflectance can be added to several OLIS models.
NIR Spectroscopy
NIR studies are becoming increasingly important in fields such as pharmaceuticals, food science, and environmental analysis. OLIS NIR systems support the analysis of complex samples and the identification and quantification of various compounds. In addition to absorbance and fluorescence NIR systems, we also offer NIR CD and CPL spectrometers.
Fluorescence Spectroscopy
Fluorescence models are available for exceptional sensitivity and precision, enabling the accurate measurement of fluorescence emission and spectra. Spectrofluorescence is used to in study the behavior of fluorophores and probing their interactions with other molecules.
Anisotropy
Anisotropy measurements, which are useful for understanding the orientation and mobility of molecules, is available on all CPL and properly enhanced fluorescence systems.
Modularity
OLIS is committed to providing researchers with the most advanced and reliable UV/Vis and NIR spectrophotometry systems, supporting groundbreaking research and discoveries in a wide range of fields. Reducing waste in science is very high priority for us, evidenced in both instrument longevity/ upgradability and reduced consumable use in sample preparation.
OLIS spectrophotometers support a diverse range of capabilities, including numerous applications on a single optical bench, due to the highly modular nature of many models.
Upcycled Spectrophotometry Systems
All OLIS products have designed-in upgradability. And some of our most popular and successful products are produced from components of older instruments which are still outstanding for their optical performance.
This embrace of sustainable practices is baked into the history and future of OLIS. Over the decades, hundreds of top quality. spectrophotometers including all OLIS models (OLIS RSM 1000, the OLIS DSM 1000 CD, the OLIS DM 45 fluorimeters, the OLIS DSM 172 CD & CPL, and the OLIS CLARiTY 245 UV/Vis, etc.) as well select classic HP, Cary, and PE models have been kept in top working condition and not relegated to the landfill.
By modernizing and upcycling spectrophotometers, OLIS extends the lifespan by double, triple, and longer, reducing waste and minimizing the environmental impact of scientific research.
Upcycled spectrophotometry systems are environmentally friendly, functionally excellent, and highly cost-effective. Researchers can access cutting-edge technology at roughly half the price. Affordability makes a top-tier instrument accessible to a wider range of laboratories, ultimately accelerating scientific discoveries and advancements in various fields.
OLIS spectrophotometry systems are revolutionizing the way researchers analyze light scattering samples and measure absorbance. For protein concentration, protein structures and interactions, and related studies using intact, whole cells rather than clarified subsets of them.
On-Line Instrument Systems is in Athens, Georgia and has been providing Uv/Vis and NIR Spectrophotometry Systems since its inception in the 1970s by Dr. Richard J. DeSa. With a vision of advancing the most challenging research goals without compromising a commitment to environmental responsibility. We have consistently strived to deliver cutting-edge solutions backed by outstanding service and fair prices.
As of January 2023, OLIS is now woman-owned and lead by Julie Ann DeSa Lorenz.
