General Description:
The Cary 5000 combines PbSmart technology with the unparalleled optical design and performance of all Cary UV-Vis-NIR instruments. It requires only one detector to extend that performance into the NIR. With innovative PbSmart™ technology, the Cary 5000 extends the unparalleled Cary performance into the NIR to 3300 nm.
