Programmable Microcontroller

The HR2000+ES has an onboard programmable microcontroller that provides flexibility in controlling the spectrometer and accessories. Through a new 30-pin connector, you can implement all operating parameters in the software, such as controlling external light sources, creating processes and routines and retrieving data from external devices. The HR2000+ES gives you access to 10 user-programmable digital I/Os for interfacing to other equipment; one analog input and one analog output; and a pulse generator for triggering other devices. (Programming the I/Os requires SpectraSuite Spectroscopy Operating Software.)

High-resolution Applications

The HR2000+ES is ideal for applications where fast reactions need to be monitored and high resolution is necessary, such as protein dynamics. 

HR2000+ES Sample Spectrum

This power-up data for our LS-1 Tungsten Halogen Light Source was taken by an HR2000+ at 2-millisecond intervals. The graph shows the tremendous amount of data generated with the HR2000+’s acquisition rate speed of 1000 spectra per second.

High-resolution "HR" Optical Bench

The exceptional ~1.33 nm optical resolution of the HR2000+ES is achieved by using the Ocean Optics High-resolution Optical Bench – a 25.4-mm diameter, 101.6-mm focal length, symmetrical crossed Czerny-Turner optical design.

Plug and Play Operation

The HR2000+ES interfaces to a computer via USB 2.0 or RS-232 serial port. When using the serial port, the HR2000+ES requires a single 5-volt power supply (not included). Data unique to each spectrometer are programmed into a memory chip on the HR2000+; SpectraSuite Spectrometer Operating Software reads these values for easy setup and hot swapping among computers.
