RAMAN-11 provides intuitive usability so that even people unfamiliar to Raman microscopy can use it. To make this happen, there are many improvements here and there in the body of RAMAN-11.
Automatic switching of laser beams that does not need adjustment of optical axis
A 785-nm laser system can be built in RAMAN-11 as an option, so that it can detect Raman light that the standard 532-nm laser system cannot due to the generation of fluorescence. These laser systems can be switched from one to the other by just a click on the screen. No troublesome adjustment of the optical axis is necessary.
Three gratings switched from one to another by a click
Three diffraction gratings are built in RAMAN-11 as standard components. A click on the screen enables switching between wide-range measurement using a grating with a smaller number of grooves and high wave number resolution measurement using a grating with a larger number of grooves.
A click enables choosing a measurement area
RAMAN-11 is equipped with a beam scanning system that uses high-precision scanning mirrors. An area for scanning can be selected by a click on the screen, and there is no need to move the stage for scanning.
The optical system and software of RAMAN-11 have been designed so that various measurement conditions can be arbitrarily set and fine-tuned. RAMAN-11 allows the measurement settings best for the sample, thus producing the best data.
Confocal slit fine-tuned by micrometer
Width of the confocal slit, which enables high three-dimensional spatial resolution, can be adjusted by a micrometer by using the software. RAMAN-11 always provides spatial and spectral resolution best for the objective lens used.
256-step adjustment of laser intensity
By controlling the ND filter built in the optical system using the software, laser intensity can be adjusted in 256 steps. It can be freely adjusted up to the threshold over which the sample is damaged.
High-precision monitoring of laser intensity
A power meter is built in RAMAN-11 as a standard component so that the intensity of an excited laser can be monitored. RAMAN-11 makes it possible to monitor laser intensity in real time and with high precision, enabling to select the optimal laser intensity.
Wave number calibration using a neon lamp
RAMAN-11 is equipped with a neon lamp, as a standard component, to calibrate the horizontal axis (Raman shift) for Raman spectra. RAMAN-11 can be used for measurement that requires precision for absolute wave numbers.
The laser, spectroscope, and optical system are all housed in a black box. The least compact body of RAMAN-11 leaves its surroundings for a working space. RAMAN-11 starts by turning a key. Users do not have to touch its hardware, except when placing a sample on the stage. The compact body has made RAMAN-11 sound and less susceptible to changes in ambient temperature, increasing the stability of data dramatically.
