HR4000 Composite-grating Spectrometer, 200-1100 nm

Our next-generation high-resolution spectrometer is a novel combination of optics and electronics that is ideal for applications such as characterizing lasers, measuring gas absorbance, and determining atomic emission lines.Features:Multiple triggering options • Resolution to 0.2 Å (FWHM) • Fast 10 µs integration time • Responsive from 200-1100 nm, specific range and resolution depends on your grating and entrance slit choices.Integration Time is a setting in our software that is specified by the user. It's analogous to the shutter speed of a camera: the value specified for the integration time is the amount of time the detector "looks" at at the incoming photons. Because the Toshiba detector has an electronic shutter, you can specify, via software, minimum integration times as short as 10 µs, which allow you to measure transient events like laser pulses. Also, the ability to integrate the spectrometer for brief durations eliminates saturation problems that can occur in high light-level applications such as laser analysis.The HR4000's onboard programmable microcontroller provides you with considerable flexibility in controlling the spectrometer and accessories. Through a 30-pin connector, you can implement all operating parameters in the software: control light sources, create processes, and retrieve information on external objects. You 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. (Programming the GPIOs requires OOIBase32 Platinum Software or one of our device drivers.)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.
