DXR™ 2 Raman Microscope

Description

Capabilities

• High performance confocal Raman microscopy in a robust, integrated design
• Autoalignment and calibration ensures scientifically accurate measurements, without tools or manual procedures
• Real-time preview, automated fluorescence correction, autoexposure, and cosmic ray rejection
• System status indicator shows the user at a glance that the system is optimized and ready to collect data
• Three-path fine beam autoalignment maintains peak performance and sampling integrity
• Laser power regulation ensures consistent sample excitation over the lifetime of the laser
• Advanced spectrograph design with no moving parts simplifies use and make the detection system and calibration robust
• Pre-aligned and lock-in-place components use automatic recognition and stored alignment, allowing any user to reconfigure an instrument in seconds
• Lasers and other components can be interchanged and shared with every instrument in the DXR2 Raman family
• Optional, automated polarized Raman capabilities provide structural information that complements chemical information
• Add new wavelengths without tools or service engineer visit

Laser Safety

• Microscope independently certified as class-1 laser safe. (Note: Optional fiber-optic accessory and some other optional accessories are class IIIb laser devices requiring laser safety precautions and laser safety eyewear.)
• Laser is physically blocked from visual viewing path to prevent exposure to the eyes while viewing.

Validation

• Complete package for DQ/IQ/OQ/PQ validation is available including extensive documentation and automated software protocols
• Omnic D/S software offers CFR 21 part 11 compliance

Exceptional Performance

• Spatial resolution—demonstrated as good as 540nm resolution on ideal sample
• Confocal depth resolution—demonstrated as good as 1.7μm on ideal sample
• Full spectral range of 3500-50cm-1 captured with a single exposure of the CCD avoids stitching artifacts. Extended spectral range to 6,000cm-1 available for 532nm laser
• Supports multiple excitation lasers. 532nm, 633nm, and 780nm
• Automatic fluorescence correction available with all excitation lasers
• Research-quality Olympus viewing optics
• Automatic intensity correction generates spectra that are comparable between instruments and different excitation lasers
• Multidimensional wavelength calibration provides accurate wavelength calibration across entire spectral range
• Proprietary Triplet spectrograph provides exceptional peak shape and maintains focus at all wavelengths
• Software controlled switching between confocal and high-energy collection modes
• Proprietary algorithm for automated cosmic ray rejection and high-quality laser line filters ensure artifact-free spectra
• Lasers depolarized to avoid confusing sample orientation effects
• Laser Power Regulator provides active monitoring of laser power and ensures reproducible laser excitation power over the lifetime of lasers and even after replacing lasers
• Optimized gratings for each excitation laser avoid performance sacrifices of systems that share gratings for multiple excitation lasers
• Proprietary autoalignment ensures system can be maintained in like-new condition
• Proprietary Smart-backgrounds automatically remove CCD dark energy profile
