The Technology
Raman Spectroscopy — the Molecular Fingerprint
Raman spectroscopy is a scattering technique that analyzes scattered light at wavelengths different from the incident laser to reveal the molecular structure of any analyte. The Raman shift — the frequency difference between incident and scattered light — is independent of excitation wavelength, determined solely by the material's energy level structure.
Each chemical bond produces a unique Raman shift, making the spectrum a true “molecular fingerprint” for identification and characterization.

System Highlights
Built for Demanding Research
Precision engineering meets intelligent automation in every component of the Finder 930.
Multi-Laser Excitation
Up to three internal lasers switchable by software, plus one external reserve interface. Standard 532 nm with optional 638 nm and 785 nm.
Confocal Raman Microscope
Upright microscope with standard epi-illumination, bright and dark field. High confocal performance with sub-micron spatial resolution.
Motorized Sample Stage
75 × 50 mm travel range with 1 μm positioning accuracy and minimum step size of 50 nm. Supports 2D Raman/PL mapping.
High-Performance Spectrograph
320 mm focal length Czerny-Turner spectrograph with F/4.2 and stray light 1 × 10⁻⁵. Spectral resolution < 1.5 cm⁻¹.
Advanced Software Analysis
Fluorescence mapping, Raman mapping, fluorescence lifetime imaging, hyperspectral data processing, cosmic ray removal, and 3D image display.
High System Stability
Built-in laser minimizes optical path length. Aviation aluminum optical mounts resist thermal and humidity deformation. Dichroic laser switching avoids motorized stage drift.

Configuration & Support
Build the Right Raman System for the Application
Finder 930 can be configured around your sample, measurement environment, automation workflow, and acceptance criteria. We can support a wide range of customization requests before final quotation.
Customization Available
Configure More Than the Standard Package
The system can be adapted for research, QA, teaching, or process-support workflows. Tell us the samples, required wavelengths, environment, mapping needs, and reporting format, and we can propose a matching configuration.
Excitation Package
Choose the laser set around your samples: 532 nm as standard, with 638 nm and 785 nm available for fluorescence control and broader material coverage.
Microscope & Objectives
Match bright-field, dark-field, long-working-distance, UV, or IR objectives to sample geometry, transparency, and expected spatial resolution.
Mapping & Automation
Specify manual or motorized sample handling, mapping area, step size, and repeatability requirements before quoting the final configuration.
Environmental Modules
Add cryostat, high-pressure, electrochemical, or heating accessories when the application needs in-situ Raman measurements.
Application Configuration
We help select excitation wavelength, objectives, stage, filters, gratings, and accessories around the measurement task.
Acceptance Criteria
Define demo samples, mapping resolution, spectral resolution, S/N, and reporting needs before installation.
Training & Workflow
Operator onboarding can cover alignment checks, Raman mapping, data export, and routine maintenance.
Custom Build Support
Custom packages can be prepared around the sample type, workflow, environment, and budget.
Analytical Method
Five Ways to Interrogate Your Sample
The intensity, frequency shift, line width, peak count, and depolarization of Raman spectra are directly linked to the vibrational and rotational energy states of the molecule.

Peak Position Changes
—Stress & Strain MappingDetect material under tension or pressure — e.g. stress on silicon wafers in semiconductor manufacturing
Polarization Analysis
—Crystal OrientationCrystal symmetry and orientation — e.g. orientation of diamond prepared by CVD
Peak Broadening
—Crystal Quality & DefectsIdentify crystal defects and dislocations — e.g. GaN substrate quality assessment
Peak Intensity
—Layer & Thickness AnalysisAmount or layers of material — e.g. monolayer vs multilayer graphene 2D peak intensities
