OLIS DSM 172 UV/Vis/NIR
Tool-free modularity for CD and CPL, and more
This uniquely versatile CD employs a prism-grating monochromator for 185-2600 nm throughput, plus an emission channel (you choose UV/Vis or NIR), and the Polarization Toolbox sample compartment.
Absorbance and CD to 1700 nm. Circularly polarized luminescence, fluorescence, and anisotropy emission 230-870 nm (extendable to NIR) and excitation 185-2600 nm.
To transition from 180 degree measurements – CD and absorbance – to 90 degree measurements – CPL & fluorescence, open the appropriate software icon and position the polarizer(s) and modulator before the sample (CD) or after the sample (CPL).
The right answer is the only answer a DSM CD can return.

"Even more, we can measure CPL signals of racemic samples irradiating only one enantiomer and evaluate the optical properties of one enantiomer even when the other one is placed into the sample. We are able to obtain GLUM values up to 0.0001."
OLIS DSM 172 : The ultimate example of an ‘endlessly upgradeable spectrophotometer’ is the Cary 14 utilized in the OLIS DSM 172. The world-class prism-grating monochromator and battleship stalwart chassis are upgraded with a xenon arc light source and the CPL Solo, creating the world’s only UV/Vis/NIR CD and UV/Vis (or NIR) CPL, while retaining the original 185-2600 nm dual beam absorbance potential. Upgrade with accessories for temperature control, thin film variable angle measurements, magnetic field, excitation polarization, and more.
Like all OLIS products, the name for this model was coined when we first conceived of its configuration. The “17” comes from the Cary 17; the “2” was added to remind us that there is a second monochromator, now an OLIS single grating model for emission. “DSM” is the elegant and digital data acquisition method common to all OLIS products with a PEM or quarter wave plate, i.e., all CD and CPLs. The first DSM 172 models are three generations of electronics and computerization behind today’s Win 10 models, but they can be upcycled to be identical to what we are producing today.
There is no downside to upcycling!
