Introduction
Product Overview
The HR4000 High-Resolution Miniature Fiber Optic Spectrometer provides optical resolution as good as
0.025 nm (FWHM). The HR4000 is responsive from 200-1100 nm, but the specific range and resolution
depends on your grating and entrance slit selections.
The HR4000 is perfect for applications where high resolution is necessary, such as absorbance of gases or
atomic emission lines (for solution chemistry or for color measurements, the USB4000 is more
appropriate).
Data programmed into a memory chip on each HR4000 includes wavelength calibration coefficients,
linearity coefficients, and the serial number unique to each spectrometer. Our spectrometer operating
software simply reads these values from the spectrometer — a feature that enables hot swapping of
spectrometers among computers.
The HR4000 Spectrometer connects to a notebook or desktop computer via USB port or serial port. When
connected to the USB port of a computer, the HR4000 draws power from the host computer, eliminating
the need for an external power supply. The HR4000, like all our USB devices, can be controlled by our
OceanView software, a Java-based spectroscopy software platform that operates on Windows, Macintosh
and Linux operating systems.
