Edmund Optics Inc. has launched a series of thermoelectrically cooled CCD-based spectrometers for low-light-level detection and long-term monitoring applications. They have 2048 pixels, a 16-bit digitizer and a USB 2.0/1.1 interface. The cooler reduces dark noise, improves dynamic range and provides operational stability. Included is intuitive Spectral Data Acquisition software that is compatible with Windows 2000, NT, XP and Vista. The spectrometers feature an SMA fiber input, measure 0.11 × 0.10 × 0.04 m and weigh 0.54 kg. They are available in UV/VIS, VIS, UV/VIS/NIR and NIR versions.
