ATR8300 Series Micro-Raman Imaging Spectrometers

Description

The ATR8300 Series is a configurable microscope-based Raman platform for laboratories requiring visually targeted micro-Raman spectroscopy, autofocus or automated chemical mapping. The family begins with base, autofocus and mapping ATR8300 configurations and extends to ATR8300Pro for applications requiring greater spectrograph flexibility, detector options, longer integration or higher spectral resolution. Multiple excitation wavelengths allow the system to be configured around fluorescence behaviour, Raman range and sample type.

Product Overview

ATR8300 integrates optical microscopy with Raman spectral acquisition so the operator can view the microscopic sample morphology and collect Raman spectra from selected locations.

The standard series is organised around three workflow levels:

The ATR8300Pro family builds on this concept with longer-focal-length spectrograph options, multiple gratings and advanced detector configurations.

This makes the family suitable for laboratories that want a Raman microscope capable of growing from routine point analysis into more demanding mapping and high-resolution research.

How It Works

The microscope provides a magnified image of the sample and allows the Raman laser to be focused onto the region of interest. Raman scattering generated within that laser spot is collected and sent to the spectrometer.

A spectrograph separates the Raman-scattered wavelengths and a detector converts them into a spectrum. The location seen by the microscope camera can then be associated with the Raman result.

For Raman mapping, the motorised stage moves through a defined area while spectra are acquired at each selected position. Software can then map peak intensity, peak position or multivariate spectral information across the sample.

ATR8300Pro Configuration

Current exact-product documentation identifies several spectrograph focal-length and detector options. Configurations include:

• FL210
• FL350
• FL510 in the current exact-product datasheet
• BS base configuration
• AF autofocus configuration
• MP mapping/autofocus configuration
• LT deep-cooled detector configuration
• SCM cooled sCMOS detector configuration

Documented excitation options include 532, 633/638, 785 and 1064 nm. Other platform revisions also identify additional wavelength options, so the final wavelength set should be confirmed in the quotation.

Why Spectrograph Focal Length Matters

The spectrograph focal length, grating and entrance slit together influence spectral resolution and the Raman range captured under a particular configuration.

Longer focal-length configurations can provide improved spectral resolution but may increase instrument complexity and size. A research group measuring closely spaced Raman bands may benefit from higher resolution, while many material-identification applications do not require the highest available specification.

• High-sensitivity research configuration with documented SNR >6000:1 on ATR8300Pro.

Selected ATR8300Pro Specifications

The Raman range and minimum resolution depend on excitation wavelength and spectrograph focal length, so they should be read from the selected configuration rather than represented by one universal number.

Applications

• graphene and other two-dimensional materials
• battery and electrode materials
• nanomaterials and nanoparticles
• pharmaceuticals and polymorphs
• semiconductor materials
• coatings and interfaces
• biological specimens
• polymers and composites
• gemstones and minerals
• chemical-distribution mapping

Compatibility and Selection Guidance

Choose the standard ATR8300 pathway if the goal is routine micro-Raman identification or conventional mapping.

ATR8300Pro becomes more appropriate when the work requires:

• improved spectral resolution
• longer integrations
• weak-signal measurements
• more detector flexibility
• multiple-grating operation
• demanding chemical mapping

The laser wavelength is a separate decision. For example, 532 nm may be useful for carbonaceous and selected inorganic materials, whereas 785 or 1064 nm can be preferable for fluorescence-prone samples.

The microscope objective also affects laser-spot size, numerical aperture and working distance. Sample geometry should therefore be discussed alongside laser wavelength and mapping requirements.

Why Source Through ScienceGears

ScienceGears can help compare ATR8300BS, AF, MP and Pro configurations, review excitation wavelength and sample fluorescence, and define spectrograph, detector and mapping requirements before quotation. This is particularly useful for universities purchasing one Raman microscope for several research groups with different application needs.

Frequently Asked Questions

What is the main difference between ATR8300 and ATR8300Pro?
ATR8300 covers routine micro-Raman, autofocus and mapping. ATR8300Pro adds a more configurable spectrograph and detector architecture for higher-resolution and more demanding research.

Do I need ATR8300MP for chemical mapping?
The MP configuration is the documented automated mapping pathway.

What does the LT suffix mean?
It denotes a deeply cooled detector configuration intended for weak signals and longer integration.

What does SCM mean?
It identifies the cooled sCMOS detector option.

Does higher spectral resolution always give better Raman results?
Not necessarily. Resolution should be sufficient to separate the bands relevant to the application. Higher resolution can involve trade-offs in throughput, range and acquisition time.

Can multiple laser wavelengths be incorporated?
Multi-wavelength configurations are available, but the permitted number and combination depend on the exact system build.
