ATR8700 Series Modular Confocal Raman Microscopes

Description

The ATR8700 Series is a modular true-confocal Raman microscopy platform for research groups requiring greater optical flexibility than a fully integrated Raman microscope. Its split architecture separates the microscope and spectrometer modules, enabling a wider range of detector, spectrograph, laser and experimental-interface configurations. The system combines adjustable confocal optics, deep-cooled detectors, automated mapping and multiple excitation wavelengths for advanced materials and microscopic chemical analysis.

Product Overview

ATR8700 is designed around modularity.

In an integrated Raman microscope, the spectrometer, microscope and laser paths are tightly packaged within one fixed architecture. That is convenient but can be restrictive when researchers want to connect specialised sample stages, external optical equipment or other experimental hardware.

ATR8700 separates the main microscope and spectrograph functions while maintaining an integrated Raman workflow. The spectrometer module can also be used independently in suitable configurations.

How It Works

The Raman laser is directed through the microscope and focused onto the sample. Raman-scattered light is collected through the objective and directed through the confocal pinhole.

The spatial aperture suppresses more out-of-focus signal before the light reaches the spectrograph. A software-controlled grating then separates the Raman wavelengths and the cooled detector records the spectrum.

The motorised stage and autofocus system can acquire spectra over a programmed area to generate Raman chemical images.

Technical Specifications

Applications

ATR8700 is particularly relevant when a laboratory needs Raman microscopy together with custom experimental integration:

• advanced materials
• semiconductor research
• nanomaterials
• electrochemical and in-situ sample environments
• temperature-controlled stages
• pharmaceuticals
• biological samples
• interfacial science
• coatings
• minerals
• weak-signal Raman research

Compatibility and Selection Guidance

ATR8700 should be considered when flexibility matters as much as Raman performance.

The modular architecture is useful when researchers anticipate integrating specialised stages or experimental cells. However, the actual optical compatibility of any external device must be confirmed before ordering.

Choose the detector after the laser wavelength has been selected. Then select focal length and grating according to required Raman range and resolution.

If laboratory space and integration simplicity are more important than modularity, ATR8600 may be a better fit. If the project requires the broadest research-grade wavelength and detector configuration, ATR8800 should also be considered.

Frequently Asked Questions

What does “modular” mean for ATR8700?
The microscope and spectrometer are separate functional modules, allowing more flexibility than a fully enclosed integrated system.

Can the spectrometer be used without the Raman microscope?
The manufacturer describes independent spectrometer use as part of the modular concept, but the required optical connections should be defined for the intended experiment.

Why cool a detector to −70 °C?
Deep cooling reduces detector dark current, which can improve weak-signal measurements and long integrations.

Can the system use three laser wavelengths?
Up to three excitation wavelengths are documented for configured systems.

Can it integrate with an in-situ cell or heating stage?
The modular architecture makes such integration plausible, but geometry, working distance and laser/sample access must be checked for the exact stage or cell.

Does it support automated chemical mapping?
Yes, autofocus and scanning/mapping are documented functions.
