Beamline 1.4 contains two Microspectroscopy endstations capable of hosting a variety of measurements.
Endstation 1.4.3 Micro-Spectroscopy
Synchrotron FTIR, Standard MCT detection, Reflection and Transmission Modes, Large area mapping. The system is presently capable of remote operation.
Frequency Range: 600 – 11,000 cm-1 (standard); other detectors available far Far-IR (< 600 cm-1 ) and Near-IR measurements (> 9000 cm-1 )
Spot Size: 2 – 10 μm (diffraction limited)
Resolution: 4 cm-1 (typical); 0.125 cm-1 possible
Standard Objectives: 32x with 0.65 N.A. and 8 mm working distance
15x with 0.58 N.A. and 15 mm working distance
10x Glass objective
Additional equipment is available — please coordinate with the beamline staff prior to submitting proposal as extra setup and testing time will be needed prior to measurements:
-
- Attenuated total reflection (ATR) down to 100 cm-1
- Ge and diamond crystals available. Light penetrates 0.6 – 2.0 μm, depending on the crystal and sample index of refraction
- Polarization control of incident light
- VeeMax glancing angle accessory
- 77 K Oxford cryostat configured for reflectance and transmission measurements. Accommodates samples up to 8 mm thick, 4-pin electrical wiring to the sample is available.
- 4 K Oxford cryostat
- Si Bolometer for Far-IR detection down to 100 cm-1
- Attenuated total reflection (ATR) down to 100 cm-1
Endstation 1.4.4 Micro-Spectroscopy
Synchrotron FTIR, Standard MCT detection, Reflection and Transmission Modes, Large area mapping, Florescence microscopy.
Frequency Range: 800 – 10,000 cm-1 (standard MCT detection)
Spot Size: 3 – 10 μm (diffraction limited)
Resolution: 1 cm-1
Additional features (under development by H.-Y. Holman, BSISB Program) include laser ablation and mass spectrometry of samples. Please contact beamline staff about the status of the endstation before submitting a User Proposal.
