inVia Raman microscope objective lens

Speed and sensitivity

High sensitivity enables you to look at weak Raman signals and rapidly analyse even minute traces of material, monolayers and weak scatterers. It uses a stigmatic on-axis optical design which provides high optical efficiency, excellent stray light rejection and unparalleled sensitivity.

High spatial resolution

The optical design enables you to achieve a very high level of confocality (the ability to reject signal from regions away from the point of interest). This ensures you achieve high stability and the highest spatial resolutions possible, limited only by the inherent diffraction limit of the light.

inVia Raman microscope objective lens

High spectral performance

It can resolve spectral features narrower than 0.5 cm-1, so you can distinguish between close Raman bands, and differentiate very similar materials, such as pharmaceutical polymorphs. High stability allows you to monitor minute shifts in Raman band position (as low as 0.02 cm-1).

Exceptional stability

A custom designed honeycomb baseplate holds the inVia microscope and lasers in position and is so stable that an optical or anti-vibration table is not normally required. Key moving components are equipped with Renishaw high precision encoders which ensures everything is correctly placed.

inVia environmental and sampling accessory

Spectral flexibility

You can configure the inVia microscope so that it is ideal for analysing your particular samples. It supports multiple lasers with automated computer-controlled switching. You can change excitation wavelength rapidly and quickly determine the best configurations to get reliable data from all your samples.

Sampling flexibility

inVia supports both research-grade upright, inverted and open frame microscopes, as well as fibre optic probes for long distance remote analysis. It is compatible with a range of objective lenses and environmental cells enabling you to analyse your samples under a variety of environmental conditions.
