Wide wavelength range spectrometer (200 ~ 1025 nm)
The SEC2120 spectrometer system is designed for a wide range of spectrometric applications, with a particular focus on spectroelectrochemical measurements. Its advanced optical design and high-performance diffraction grating enable highly sensitive measurements across a broad wavelength range, covering ultraviolet to near-infrared regions (UV/VIS/NIR) within a single unit.
The SEC spectrometer features a high-speed CMOS detector capable of extremely short exposure (integration) times of up to 100 µs, making it suitable for measuring high-intensity light. The system includes compact, modular deuterium and halogen light sources, which are aligned with the cell holder and mounted on an accessory platform for convenient operation.
By attaching a collimator lens to the light source, an SMA905 interface is provided for optical fiber connections, while the spectrometer itself also supports direct connection via an SMA905 optical fiber.
