EXPEC-6000 is a developed product by Focused Photonics (Hangzhou), Inc. It is an achievement based on many years of extensive research and development of optical spectrum analyzing equipment. EXPEC-6000 has a rich spectral library with more than 50,000 optical spectrum lines available for selection and has a synchronous measuring ability to analyze 72 elements simultaneously. Via a new approach of industrial design, EXPEC-6000 also includes an optimized design of a two-dimensional spectroscopic system of middle ladder grating, an automatic fixed RF power supply, a custom-made anti overflow CCD and full-automatic spectrum acquisition system, an argon gas logic controller as well as a light chamber temperature control system. All in all, this makes EXPEC-6000 have properties of high resolution, extensive dynamic range, high stability, and low limit of detection.
