EK2000-Pro Scientific High-Sensitivity Fiber Optic Spectrometer

Product Introduction
The EK2000-Pro is a compact, high-sensitivity fiber optic spectrometer designed for scientific research, laboratory analysis, and industrial applications. Equipped with a back-illuminated area-array FFT-CCD detector and a unique crossed optical design, it delivers high sensitivity, high quantum efficiency, and a wide dynamic range, with configurations capable of extending into the deep ultraviolet region.
The spectrometer is particularly suitable for weak-light measurements, including fluorescence detection and other demanding optical analysis applications. Its USB 2.0 interface provides data communication at up to 480 Mbps while supplying power through the USB connection, simplifying system integration and portable operation.

Performance Features
• High-sensitivity CCD detector: Back-illuminated FFT-CCD technology improves light collection efficiency for weak-signal measurements.
• High optical resolution: Optical resolution can reach approximately 0.035 nm FWHM, depending on the optical configuration.
• Wide spectral coverage: Configurable wavelength coverage extends up to 200–1100 nm, depending on the selected grating.
• Advanced crossed optical design: Helps suppress stray light and improve spectral measurement quality.
• Wide dynamic range: A specified dynamic range of 10000:1 supports measurements across varying signal intensities.
• High-speed USB connectivity: USB 2.0 communication at up to 480 Mbps with USB-powered operation.
• Optional order-sorting filters: Help suppress second- and third-order diffraction peaks.
• Optional detector condenser lens: Enhances light collection to improve signal acquisition.
• Compact and portable construction: Suitable for laboratory setups, portable instruments, and integrated optical measurement systems.

Working Principle
The EK2000-Pro uses a diffraction grating to disperse incoming light into its constituent wavelengths. The back-illuminated area-array FFT-CCD detector converts the dispersed optical signal into electrical charges, which are read out and digitized for spectral analysis.
Its crossed optical configuration helps reduce stray light, while the high-sensitivity detector supports the acquisition of weak optical signals. Optional order-sorting filters reduce unwanted higher-order spectral contributions, and an optional condenser lens improves light collection efficiency.
The resulting digital spectrum can be used for fluorescence measurements, optical characterization, and other scientific or industrial analytical applications.
