  • LAS Modules for Metallographic Applications
Jan 2013
Leica Microsystems GmbHRequest Info
WETZLAR, Germany, Jan. 10, 2013 — Leica Microsystems GmbH has released LAS 4.2, the latest version of its Leica Application Suite (LAS) digital imaging software.

The range of metallographic applications has been extended with two additions: Leica Decarburisation Expert and Leica Dendrite Expert.

Leica Dendrite Expert analyzes microscope images of dendrites in metals and alloys using a similar interface to other Expert materials applications. With both semiautomatic and manual methods available, the dendrite arm spacing can be determined on a variety of suitable specimens. The results assist in qualifying material to specifications determined between purchaser and manufacturer.

Results from Leica Dendrite and Decarburisation Expert can be output to Excel reports. Default templates are provided that can be customized to meet company requirements.

Leica Decarburisation Expert analyzes microscope images of decarburization in steel. The depth of decarburization is determined automatically on suitable samples by image analysis, or manually for other samples. The carbon loss at the surface of the specimen is compared with the amount present in the unaffected interior, and the results are output to an Excel report.

LAS MultiStep is enhanced with Guided Mode. LAS MultiStep uses a motorized stage to capture panoramic images, larger than the field of view. Guided Mode improves the quality of the final image by matching features in adjacent images and adjusting their position to ensure a perfect match. Combining the Live Measurement module with a motorized stage, it is easy to accurately measure the distance between features that are separated by more than one field.

Leica Application Suite provides an environment for all microscope imaging needs. It combines the microscope, digital camera, accessories and image processing. LAS Core provides camera and microscope control and basic documentation facilities. With 24 modules and 10 Expert applications available, LAS can be configured to meet individual needs now and can be extended as requirements change. The wide range of modules includes measurement, automated image analysis, extended depth of field, field of view, movie, time lapse and a macro facility. The Live Image Builder modules extend the microscope’s imaging capability.

digital camera
A camera that converts a collected image into pixels that are black or white digital or shades of gray. The digital data may then be manipulated to enhance or otherwise modify the resulting viewed image.
guided mode
In an optical waveguide, a mode whose field decays monotonically in the transverse direction everywhere external to the core and which does not lose power to radiation. Also called bound mode.
An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
