CPL Introduction, 1970’s to Today

Arguably the first use of “circularly polarized luminescence” dates to 1974, “Circularly polarized luminescence of terbium (III) complexes in solution” (C. K. Luk & F. S. Richardson, Chem. Phys. Lett., 1974). (ScienceDirect)  (A few years earlier were S. S. Eaton’s 1971 paper “A new method for determining optical purity, using circular polarization of luminescence” and several 1971–1974 papers on magnetic circular polarization and related theory.)

This 1993 chapter in Methods in Enzymology by Richardson firmly established CPL as a technique of serious merit. [22] Circularly polarized luminescence - ScienceDirect

Richardson and Riehl encouraged Richard DeSa to develop CPL equipment. We had our first buyer for one in the 2000s. This earliest model was the OLIS DSM 172, the combination CD and CPL.  

 

The CPL Solo was developed in 2019. Its small size, affordability, and exquisite sensitivity has made it the market leader in this new and rapidly growing field. Owners of the CPL Solo include:
