High-performance, entry-level Raman for reliable, routine analysis
Product Overview
The inVia Basis is the entry-level model range of research-grade confocal Raman microscopes. It combines a robust spectrometer with a Leica DM2700M optical microscope, delivering excellent signal throughput, spectral resolution and stability. Fully automated and upgrade-capable, inVia Basis is ideal for academic labs, quality-control facilities and industrial R&D groups that need dependable Raman data today and the flexibility to expand tomorrow
Key Features
- High optical efficiency and sensitivity
- Stigmatic on-axis spectrometer design yields maximum signal throughput and stray-light rejection, so even weak Raman scatterers (thin films, monolayers) are detected.
- Automated operation
- Motorised laser, filter and grating switching plus internal neon lamp and reference standards ensure focus, alignment and calibration are maintained without user intervention.
- Confocal performance
- EasyConfocal™ optics delivers sub-micrometre spatial resolution and true confocal sampling, for chemical mapping in 2D or 3D without compromise.
- Flexible laser excitation
- Supports up to three directly-coupled lasers (e.g. 514 nm, 785 nm), with user-changeable kinematic mounts for additional wavelengths or future upgrades.
- Stereo and video viewing
- Binocular eyepieces plus combined white-light/laser video camera let you locate and align features quickly; automatic white-light saving with every map saves context with every data set.
- WiRE software
- Comprehensive Windows-based software controls acquisition, mapping, spectral libraries, background subtraction, cosmic-ray removal and multivariate imaging — all via intuitive workflows.
