WITec alpha300 apyron Confocal Raman
Main content start
Overview
Confocal Raman spectroscopy and imaging provides specific chemical information about your materials with sub-micron spatial resolution.
Typical Raman applications include:
- Chemical Identification & Mapping
- Non-Destructive, Label-Free Analysis
- Depth Profiling & 3D Analysis
- Crystallinity & Phase Identification
The WITec alpha300 apyron features:
- 2 laser sources: 532 nm, 785 nm with notch filters (RayShield) that allow users to measure down to 10 cm-1 and evaluate both Stokes and Anti-Stokes Raman.
- Three detectors to optimize performance and detect visible to Near IR:Visible:
High Quantum Efficiency Back Illuminated EMCCD Camera (500-700 nm) | Gratings 600 & 1800 grooves/mm
Near-IR: High Performance Low-dark current CCD Camera (550-950 nm) | Gratings 300 & 1200 grooves/mm
Extended Near-IR: InGaAs Spectroscopy Camera (1000-1600nm) | Gratings 150 & 600 grooves/mm - Laser power adjustment with TruePower™ - Optimal laser power determination for the preservation of delicate samples and reproducibility
- TrueSurface™ - WITec's patented microscopy option uses an advanced optical profilometer integrated within the instrument to provide one-pass simultaneous acquisition of both topographic and molecular information.
- Motorized Polarization option - a polarization kit for rotating the polarization of the laser light and an analyzer for analyzing material properties that are polarization dependent.
Compatible with Linkam Heating and Cooling Stage (-190°C - 250°C) with Electrical Contacts
