GMDX
GMDX、GMDXc Spectrometer
GMDX is micro Raman/PL system. All-in-one compact system includes XYZ three-axis sample stage, 5 M pixel CCD camera, 10X lens. Customers can change different magnifications of objective by yourself.
GMDX can choose different laser wavelengths according to different applications. It could be micro Raman or micro PL, for example, 535~1100nm PL or 79 ~3500 cm-1 @532 nm laser. The spot of laser on sample should be 0.3 mm.
GMDX is extremely versatile for various kinds of samples, such as solid, liquid, powder, thin film, paste, gel, diamond and gem.
Two Ways Controlled the power of Laser
The power of Laser could be controlled by software, at 1 mW/step for RGB Lasersystems, one of the major laser brands used in MRID. In addition, laser power could be reduced by a round continuously variable neutral density filter (O.D 2.0~0.04) that is also controlled by software with high precision. That means the minimum power of laser can reduce to 0.01 mW
GMDXc could
be customized called GMDXc which incorporates special cooling
CCD systems that permits continuous operation without thermal noise, it
could be provided to many advantages features as high stability, high
sensitivity, high-speed acquisition and low noise.
