05 Dec 2006 HR4000 Spectrometer Enables Optical Resolution as Precise as O.2 nm (FWHM) Dunedin, Fla., November 2006 - The HR4000 from Ocean Optics achieves sub-angstrom optical resolution in a 4-inch focal length optical bench. The HR4000 has a 3648-element CCD-array detector that enables optical resolution of 0.02 nm (FWHM), making it ideal for characterizing ultra-fast lasers, measuring gas absorbance, and determining atomic emission lines. The HR4000 has an electronic shutter for setting integration times as fast as 10 microseconds and an onboard micro-controller to trigger other devices.
The HR4000's onboard programmable microcontroller provides users with considerable flexibility in controlling the spectrometer and accessories. Through a 30-pin connector, users can implement all operating parameters in the software: control light sources, create processes, and retrieve information on external objects. Users have access to 10 user-programmable digital Inputs/Outputs for interfacing to other equipment; one analog input and one analog output; and a pulse generator for triggering other devices.
The HR4000 interfaces to a PC, PLC or other embedded controllers via USB 2.0 or RS-232 serial port. When using the serial port, the HR4000 requires a single 5-volt power supply (not included). Data unique to each spectrometer are programmed into a memory chip on the HR4000; our spectrometer operating software reads these values for easy setup and hot swapping among PCs.
