SPM3 Strong-Signal Fiber Optic Spectrometer SPM3-200-800
SPM3 is a Hamamatsu CMOS-based fiber spectrometer with 4096 pixels, high sensitivity in UV and VIS, high performance and low cost. Multiple external interfaces provide stable, convenient spectral acquisition. Gratings come from the USA/Japan, the detector from Japan and core hardware from the USA/Germany/Japan. 1. A 4096-pixel detector and sensitive 16-bit AD converter provide high performance. 2. TTL, 485, Modbus and RS232 interfaces simplify integration. SDK secondary development reduces redevelopment costs. 3. High-speed transfer: integration time 0.06 ms-65m, maximum 4000 frames/second, high signal-to-noise ratio and high stability.
