Product catalog summary

General Specifications
The cryoRaman is a confocal Raman microscope designed for low temperatures and high magnetic fields. It is compatible with a toploader cryostat or can be integrated into an optical table. It features high NA cryogenic objectives such as LT-APO/532-Raman, LT-APO/633-Raman, and LT-APO/NIR, with others available upon request. Key features include the detection of Raman peaks down to less than 10 relative cm^-1 and various upgrades including polarization control.

Modes of Operation
The instrument supports single point measurements or imaging (mapping) of Raman, photoluminescence, or fluorescence. Optional upgrades include polarization control and analysis.

Resolution
The lateral resolution is less than 400nm and the vertical resolution is less than 2µm, both for 532nm excitation.

Detection
It includes a mirror-free high throughput spectrometer with f=300, with other options available. Filters include <90cm^-1 (RayLine Coupler) and <10cm^-1 (RayShield Coupler) Raman cut-off (optional). Gratings for 532nm excitation are 600/mm and 1800/mm on an automated triple grating turret. The spectral resolution is less than 1cm^-1/pixel with the 1800/mm grating. The CCD camera is a high-sensitivity back-illuminated detector, peltier-cooled to -60°C, with 1024x127 pixels and 90% quantum efficiency at 532 nm.

Sample Positioning
The total travel range is 5 x 5 x 4.8 mm³ (open loop) with a step size of 0.05 to 3 µm at 300 K and 10 to 500 nm at 4 K. The fine scan range is 50 x 50 µm² at 300 K and 30 x 30 µm² at 4 K (open loop). Sample holders include ASH/QE/8/CFM or ASH/QE/4CX.

Suitable Operating Conditions
The temperature range is 4K to 320K with the attoDRY800 and LT-APO shroud, and 1.8K to 300K with the attoDRY2100. The magnetic field range is up to 12T, depending on the magnet.

Excitation
Excitation wavelengths include 532nm, 633nm, 785nm, with others available upon request.

Scan Controller and Software
The scan controller is a WITec USB 3.0 FPGA-based system providing open loop control of the cryogenic piezo-scanners, spectrometer control, and full automation control. The software package includes powerful tools for video and data acquisition and analysis.

Inspection Optics
The field of view is greater than 40µm diagonal, with a color video image camera providing good contrast for materials like 2D materials.

Options and Upgrades
Automation options include TruePower (calibrated laser power), automated shutters, and automated switching between white light and Raman. Additional feedthroughs for DC and high-frequency lines and optical fiber are available. Add-ons include additional optical breadboards for home-built optics experiments (attoDRY2100) and various sizes for optical table upgrades (attoDRY800). Software upgrades include TrueMatch for spectra analysis and building a spectral library, and a LabVIEW package for integrated control of temperature, magnet, and Raman software.
