Recent advancements in quantum technology have highlighted the potential of nitrogen-vacancy (NV) centers in diamond. However, realizing this potential requires overcoming challenges associated with the size, complexity, and cost of current optical systems. In this Perspective, we present a compact and portable confocal setup designed for efficient detection, initialization, and readout of single NV center photoluminescence signals, enabling coherent spin control and nanoscale-resolution magnetic field sensing.
