EK2000 Pro-TEC Passive-Cooled High-Sensitivity Array Fiber Optic Spectrometer
Product Introduction
The EK2000 Pro-TEC is a high-sensitivity array fiber optic spectrometer designed for scientific research and industrial applications. Featuring a passively cooled, back-illuminated CCD detector with 2048 × 64 pixels, it delivers excellent sensitivity across the ultraviolet and near-infrared regions.
Its integrated passive cooling system reduces the detector temperature by up to 30°C below ambient temperature, helping improve signal-to-noise ratio and response uniformity. Combined with dual-blazed gratings, higher-order diffraction suppression filters, and flexible external triggering, the EK2000 Pro-TEC is well suited for weak-light measurements, fluorescence analysis, Raman spectroscopy, and synchronized industrial monitoring.

Performance Features
• High UV sensitivity: CCD quantum efficiency reaches 70% in the ultraviolet region.
• Passive CCD cooling: Reduces detector temperature by up to 30°C below ambient temperature, with a minimum operating temperature of 5°C.
• Smooth spectral output: Improved etalon characteristics help reduce interference effects.
• Wide spectral coverage: Measures wavelengths from 190 to 1100 nm using dual-blazed gratings and wavelength-matched order-sorting filters.
• High-quality optical performance: Typical optical resolution of 0.12 nm FWHM, depending on the selected wavelength range.
• Flexible triggering: Supports free-run, level-triggered, edge-triggered, and synchronous-triggering modes.
• Multiple interfaces: USB, serial, SPI, and a 30-pin Chenchang GPIO interface.
• Software development support: ChNetDriver SDK supports multiple programming languages and enables integration with laboratory and industrial systems.

Working Principle
The EK2000 Pro-TEC uses a grating-based optical system to separate incoming light into its component wavelengths. The dispersed light is detected by a passively cooled, back-illuminated CCD array, which converts optical signals into electrical signals for digital processing.
The integrated cooling system helps reduce detector noise and improve measurement stability, particularly under weak-light conditions. Dual-blazed gratings and suitable order-sorting filters support efficient spectral measurement across the 190–1100 nm range. External triggering and software integration enable synchronized acquisition for automated testing and online monitoring.
