Color centers in diamonds have proven to be promising quantum emitter candidates for many applications in quantum information and quantum sensing. Not only do they serve as efficient single photon sources at room temperature, but they also enable the analysis of spin dynamics and spin coherence times. Conventional detection approaches using high-NA microscope objectives and intricate piezo positioning systems [1] have turned out to be expensive and sophisticated [2]. In response to these challenges, our setup utilizes Blu-Ray optical pickup units (OPUs) [3] and offers a cost-effective solution to enhance access to single-photon research. These OPUs have built-in aspheric lenses and positioning mechanisms which we utilize to identify emitters and successfully measure single photon emssion from NV nanodiamonds.
