LaVision offers a wide range of high quality standard lenses covering a range of working distances and fields of view. Please consult with your LaVision representative which one can meet your requirements.
The Zoom Lens System with 12x magnification range consists of a main lens body and a variety of attachments to get application-specific working distances and fields of view. The Zoom Lens System design has an advantage over conventional photographic lenses due to its versatility in variations of working distances and magnifications.
The Long Distance Microscopes allow an extremely high magnification and resolution while maintaining a long working distance. Due to the special telescope design a large variability in field of view and remarkable depth of field can be achieved. The use of high quality mirrors is an advantage over lens systems in terms of linearity and chromatic correction. This makes them ideal optics for high resolution imaging applications.
For high temperature applications LaVision offers a specific camera filter intended for use in combination with the blue LED illumination units.
To eliminate glare and specular reflections from the specimen surface and greatly improve usability and result quality.
Metallic or shiny surfaces can create unwanted specular reflections which can confuse the correlation algorithms. Such reflections may not be visible at the start of a test but as the specimen deforms, the local light incidence changes and these bright spots can occur. The polarization light upgrade kit includes the necessary filters for the standard LED illumination units. In combination with optical filter rings for the camera lenses this configuration significantly reduces this effect thus improving data quality.
