UV-VIS-NIR LabRAM HR

In order to meet increasingly demanding requirements for ease of use, versatility and flexibility, the UV-VIS LabRAM HR incorporates new techniques in optical system design. With carefully selected and optimized components (new CCDs, Objectives, coatings, and gratings) and with new optical solutions (coupling optics, spectrograph design, automation) a high throughput and UNIQUELY UV-VIS capable instrument has evolved.

FAST OPERATION
Unlike achromat based systems the DUAL PATH optics of the LabRAM HR UV-VIS-NIR offers fast, simple switching between UV and VIS/NIR regions. No adjustment or alignment is required.
BROAD SPECTRAL RANGE
A further benefit of the UNIQUE Dual Path optics is that the instrument functions over the widest spectral range - without compromising sensitivity or spatial resolution. It can thus be applied to PL emission along with Raman measurements for samples such as GaN.
HIGH RESOLUTION
Unlike the smaller bench-top instruments, the LabRAM HR has a long 800mm focal spectrometer integrated within the instrument. The longer focal length enables the spectral resolution of the instrument to be maintained even when operating down in the Deep UV. (Typically a resolution of 1 cm^-1/pixel in this UV region, is achieved compared to ~4 cm^-1/pixel with the smaller instruments available.)
