Description
Pina, NanoQ, Mic, Tuna, and Stea are next-generation compact semiconductor light sources from Oriental Spectra for advanced optical applications. Each series includes variants based on semiconductor laser and LED technologies. These sources cover a broad spectral range from UV–Vis–NIR and support picosecond, nanosecond, microsecond, pulse-width-tunable, and continuous-wave operating modes. All models feature synchronized trigger output and flexible external trigger input. They can be used as standalone laser modules for custom free-space optical setups or coupled with spectrometers and fiber optic systems. The Stea series, a CW semiconductor light source, offers high stability, high output power, and fiber coupling capability, and is designed for fluorescence quantum efficiency, detector response, and photoconductivity measurements. It is commonly applied in research on phosphors, dyes, organic semiconductors, perovskites, and quantum dots.
