DXR3 Raman Microscope

Manufacturer – Thermo Fisher Scientific

Description: DXR3 Raman Microscope is an easy­-to­use “point‑and‑shoot” confocal Raman microscope that provides fast, reliable chemical imaging and high spatial resolution. It features automatic alignment, calibration, and laser‑power regulation to ensure reproducible results with minimal operator intervention.

Technical Specifications:
Spatial (X, Y) resolution: as fine as 540 nm on an ideal sample.
Confocal depth (Z) resolution: as fine as 1.7 µm on an ideal sample.
Spectral range: 3,500 to 50 cm⁻¹ captured in a single CCD exposure; extended up to ~6,000 cm⁻¹ available using a 532 nm laser.
Supported excitation lasers: 455 nm; 532 nm (high brightness / high power); 633 nm (high brightness / high power); 785 nm (high brightness / high power).
Laser power control: fine regulation at the sample, reported in 0.1 mW increments.
Electrical requirements: 100‑240 V, 47/63 Hz.
Operating temperature range: 16 °C to 27 °C.
Laser safety: Certified as Class 1 laser safe in standard configuration (optional accessories may be Class IIIb).
Key Features:
• Automatic X‑axis calibration for enhanced reliability and stability.
• Auto­alignment, auto­calibration and tool‑free reconfiguration of optical components.
• Real‑time preview, automated fluorescence correction, auto­exposure and cosmic‑ray rejection.
• Laser power regulator ensures consistent excitation over the lifetime of the laser.
• Pre‑aligned, lock‑in‑place components and shared modular lasers/filters for fast configuration.
• Advanced spectrograph design with no moving parts (triplet spectrograph) for robust calibration and excellent spectral peak shape.
• Research‑quality optics and smart background correction to maintain spectral integrity across different lasers and instruments.
• Certified Class 1 laser safety for simplified lab integration.
Applications: Ideal for pharmaceutical analysis (polymorphs/contaminants), microplastics and particulate analysis, advanced polymers and materials science, nanotechnology (graphene, CNTs, coatings), forensics and academic research.
