Confocal Micro Raman System

• Up to three excitation wavelength available.

• < 1㎛ x, y spatial resolution and < 2㎛ depth resolution with true confocal design.

• Fully motorized system.

• The FEX can be easily integrated in most upright and inverted microscopes. (Olympus, Nikon, Leica, Carl Zeiss and etc.) It can be possible to integrate with overall microscopy performance such as fluorescence, dark-field and DIC imaging.

▶ General performance

                        <50 cm-1 @ low wave cut-off filter for multiple laser lines ( optional).

• Spectral resolution : average 2.1 cm-1 / CCD pixel @ 1200gr/mm, 650 nm
                             average 1.0 cm-1 / CCD pixel @ 2400gr/mm, 650 nm
                             optional 0.5 cm-1 ( or better) with suitable optics @ HRS mode.
