In the precise optoelectronic fields such as spectral analysis, material optical characterization, laser detection, photoelectric response testing, and weak light signal acquisition, the response sensitivity, spectral adaptability, and signal conversion stability of the detector are the core keys determining the accuracy of experimental data and the reliability of the system. Traditional detection devices generally have problems such as low response sensitivity, narrow band coverage, high signal delay, and large coupling loss, making them difficult to adapt to high-precision, automated, and weak signal detection scenarios in scientific research and industrial applications. The Sevan Optoelectronics 7ID2 series of silicon detectors, relying on mature silicon photoelectric effect technology, are divided into two versions: ultraviolet enhanced type and general type. With wide spectral response, high conversion efficiency, ultra-fast response speed, and low loss coupling, they have become the core components of standardized optoelectronic detection in the ultraviolet-visible-near-infrared band.
The 7ID2 series of silicon detectors have excellent photoelectric conversion performance, and different models precisely adapt to various detection requirements. Among them, the 7ID219 ultraviolet enhanced detector has a peak wavelength response sensitivity of up to 0.5 A/W, and the response sensitivity in the 200nm ultraviolet band is stable at 0.1-0.12 A/W, perfectly compensating for the weak ultraviolet response deficiency of ordinary silicon detectors and achieving wide-spectrum precise detection from deep ultraviolet to near-infrared; the 7ID230 general type has balanced performance, with a peak response sensitivity of 0.4 A/W, suitable for conventional visible light and near-infrared spectral detection scenarios. The entire series of products has an ultra-fast response speed of only 3μs, with no delay or distortion in signal capture, and can precisely match high-demanding conditions such as high-speed spectral scanning, dynamic light signal acquisition, and laser instantaneous detection.
The product adopts an industrialized precise integration design, with a standard SMA905 fiber optic interface, plug-and-play without complex debugging, with a light coupling efficiency of over 90%, completely avoiding free light path scattering loss, and significantly improving the utilization of light signals. The standardized installation size enables seamless compatibility with Sevan's entire series of optical equipment, perfectly linking triple grating scanning monochromators, fiber-specific halogen lamps, high-voltage stabilized power supplies, and electrically adjustable double-opening slits, quickly building a standardized and integrated precise optoelectronic testing system. The body structure is compact and sturdy, resistant to interference and low noise, with stable and no drift signals during long-term continuous operation, effectively reducing experimental errors and ensuring the repeatability and accuracy of test data.
The detection scenarios cover the entire research and industrial detection fields, and can be widely applied to material transmission and reflection spectroscopy testing, fluorescence and Raman spectroscopy analysis, semiconductor photoelectric response detection, photovoltaic device efficiency calibration, laser energy monitoring, biological optical detection, industrial online spectral quality control, etc., fully meeting the high-precision detection requirements of universities for cutting-edge research, enterprises for precise development, and institutions for metrological calibration. It is a high-performance, cost-effective, and stable general-purpose silicon detector core component.
By precisely capturing weak light signals through photoelectric conversion and empowering precise research with stable core performance, the Sevan Optoelectronics 7ID2 series of silicon detectors, with multiple versions precisely adapting and full-band efficient detection, build the core sensor for various optoelectronic testing systems, helping to upgrade the standardization and precision of optical detection.
