法国Thomson公司提供的TH7885M是一种光谱学应用中使用的新型CCD面阵列成像器。其像素为1024×256(19×19μm),具有19.45×4.86mm的成像区。在-40℃时暗电流可达到0.3电子/像素/秒。此器件含有低噪声输出放大器,其动态范围达16bit。该公司声称,用紫外镀层或减簿技术可使该器件的400～1100nm的标准光谱范围扩展到紫外波段。
The TH7885M from Thomson France is a new CCD area array imager for spectroscopy applications. Its pixels are 1024 × 256 (19 × 19 μm) with an imaging area of 19.45 × 4.86 mm. Dark current can reach 0.3 electron / pixel / second at -40 ℃. This device contains a low noise output amplifier with a dynamic range of up to 16 bits. The company claims that the device can be extended to the ultraviolet spectral range of 400 ~ 1100nm spectral range UV coating or subtraction technology.
