inVia: sampling flexibility
In addition to the vast array of objective options and environmental cells, Renishaw provides a host of inVia specific options. These ensure your sample can be accessed and controlled, whatever your experimental needs.
Look up, look down, look big
Micro-Raman systems use microscopes to provide the highest spatial resolution and efficiency.
Do you need to look at large samples, too big to fit under the standard microscope?
Do you need to look at a Petri dish from underneath?
You can configure your inVia to make these tasks easy.
Renishaw's inVia supports a range of research-grade upright and inverted microscopes - including multiple options. Choose from microscopes that include:
- standard, upright
- free space (large frame) options
If these options aren't suitable, our Special Products team will design a custom solution for you. Our aim is to provide you with the ideal sampling conditions to meet your needs.
Accurate and precise sample positioning (HSES)
The Renishaw high speed encoded stage (HSES) provides manual and motorised control of the sample position in X, Y, and Z. The stage is encoded enabling 100 nm steps to be used. Custom velocity control algorithms optimise fast motion over large and small distances. This speed is used for the StreamLine™ and StreamHR™ fast Raman mapping methods.
Look in depth with transmission Raman
Configure your microscope-based Raman system to efficiently sample large volumes of material. This enables you to understand the homogeneity and mixing of large volume samples, and the concentration of ingredients.
Renishaw's inVia supports transmission Raman experiments for averaging throughout the sample volume. Add this capability to your system without affecting any existing functionality.
When combined with Renishaw's HSES, transmission Raman also enables you to analyse much larger volumes by mapping the sample surface with a series of transmission Raman measurements.
Stable sample mounting (HSES accessory kit)
To complement the HSES, this accessory kit enables a variety of samples to be positioned and immobilised. This is achieved using a range of mechanical and magnetic clamps. Whether you want to keep the sample flat or stop it sliding around, there is a considered option.
The flat surface plate is perfect for very large samples which fill the HSES stage.
Keep your mapping fast and ensure the sample is solidly positioned.
Flexible sample manipulation (HSES insert plates)
The HSES has been designed to accept different inserts to perform a variety of functions. From well plates to rotating slide holders, the sample stage can be adapted for the exact requirements of your experiment.
Flexible objective positioning (flexible sampling arm)
If you want to analyse very large samples—with all the benefits of direct coupling—this sampling accessory provides a simple and easy way to do this. Featuring HSES motorised control of the rotation, extension, and angle of the objective, this arm sits in place of the objective on the microscope turret and is installed in seconds. It can even be used to map sample regions of the large sample!
Perform Raman in your equipment (flexible coupling arm)
Building on the concept of the flexible sampling arm, the coupling arm controls the X, Y, and Z position of the objective externally to the HSES. Combined with independent video with white light illumination and even more flexible control of objective angle, accessing tight areas becomes simple, even at the most awkward of angles. As light is collimated, large distances can be covered with minimal additional optics needed, keeping throughput high.
No matter where your sample is located, direct coupling provides all the sensitivity, spectral resolution and scanning benefits, of inVia.
Long distance remote analysis (fibre optic probes)
Provide the ultimate in convenience and flexibility and take Raman to your sample, rather than moving the sample to the inVia. This enables analysis on large or immovable objects that are not suited to a normal microscope arrangement.
These probes perform the function of a microscope and Rayleigh filters. With an optional video camera and illumination package, this makes it easy to position and focus on the correct part of your sample, far away (tens of metres or more) from the Raman system.
With inVia, fibre probes are an efficient option, using existing lasers already configured with the system. Analysis can be switched between the probe and microscope automatically through the WiRE software, providing simple and convenient use.
