Ocean Optics Inc. has unveiled the PC2000, a plug-in spectrometer that offers greater sensitivity than its predecessor, the PC1000. It is mounted on a half-length ISA bus A/D card that installs in an ISA bus slot in a PC. Invisible to the end user and occupying a single card slot in the PC, it requires no bench space. The PC2000 combines a UV-VIS-short-wave NIR spectrometer with a 1-MHz, 12-bit A/D system. It features a compact optical bench coupled to a 2048-element CCD linear array detector.
