Performance and use of concave grating spectrometer

Generally speaking, a concave grating spectrometer is a kind of Diffraction Grating. It is used in a specific environment, so it also has special parameter performance, including five points as follows:

1. The concave grating spectrometer is operated and analyzed by Ocean Optics' Spectrasuite spectrum operating software, and can be used on Windows, Macintosh, and Linux operating platforms. It is also compatible with Ocean Optics' OmniDriver and SeaBreeze software development platform.

2. The spectrometer has the characteristics of high light transmittance, lower stray light, and good thermal stability, and can be used for absorption and fluorescence measurement of liquids and solids. Torus visible band spectrometer (360nm-825nm), stray light level: at 400nm, about 0.015%, lower than the plane grating and other miniature fiber spectrometers.

3. Flat-field optical design and Holographic Concave Grating for light dispersion: the concave surface of the concave grating spectrometer grating is used for light reflection and convergence; the grating line is used for light dispersion; the ring design of the grating is used for aberration correction to improve Diffraction efficiency.

4. The grating instrument has high optical resolution (<1.6nmFWHM, 25um slit) and excellent thermal stability (within the range of 0-50℃, the wavelength drift is smaller, and the peak shape remains basically the same).

5. And this type of grating spectrometer can be controlled interactively with the computer through the USB interface, and the slits, filters and other Accessories can be changed according to customer needs to optimize the configuration; it can also be used in conjunction with the microscope through the C-mount interface. Together with other optical accessories of Ocean Optics, it makes your measurement more convenient and flexible.
