Raman Spectroscopy Systems
From Handheld toConfocal Raman
Seven instruments, one technique. Pick the form factor by where the measurement happens and who takes it; pick the excitation line by the sample. Every system is supplied with configuration support, installation and training.

Identify a material on site, no spectroscopist present?
Finder Edge for pocket-sized one-click checks; FI-FO when a probe has to reach into vessels; FI-Lite for liquids and SERS.
A bench instrument for QC, teaching or forensics?
Finder Insight Pro — a complete desktop Raman microscope at 8 kg, with 96-well plate and vial accessories; T-RamanSys when a fibre probe and library search suit the workflow better than a microscope, or its diamond-identification configuration for gem labs.
Research resolution, low-wavenumber modes and mapping?
RTS-mini on the upright microscope you already have; Finder 930 when you need several lasers, automated mapping and environmental cells.
