Leica DM4 P for Research and Development

Description

Fully coded and semi-automated. The Leica DM4 P automatically detects which contrast method and objective are being used. This provides valuable consistency and reproducibility for your research. Manual diaphragm setting is no longer required, either in the transmitted light or incident light method. Light intensity automatically adjusts to the objective. Image brightness remains constant when switching objectives, which eliminates glare. The Leica DM4 P transmitted and incident light axis are now equipped with state-of-the art high-power LED illumination, contrastable to 100 W halogen lamp. The long lifetime LED with at least 50.000 h is suitable for all incident and transmitted light contrasting methods. By the constant color temperature at all light intensity levels the object appears always at its real color.

If you want to do everything in polarization microscopy, you can with the Leica DM4 P.

Store and recall information with coded components

When you change objectives, illumination intensity and aperture settings are recalled with the Illumination Intensity Control and Contrast Manager.
Acquired images are always calibrated due to the coded nosepiece.

Identify interesting structures

With the large 25-mm field of view you get a perfect overview.
A lower magnification rather than the detailed view often reveals the specific information you need – just think of flow or deformation structures or zonation by cooling processes.

Best of Both Illuminations

You can configure the Leica DM4 P with LED illumination either for transmitted light or incident light or with LED for both transmitted light an incident light in one go.

Incident light is mandatory for all who perform reflectivity measurements, for example looking at ores or coal.
Transmitted light is required for birefringence measurements, for example in inspection of geological thin sections, polymer foils, or drugs.
For specific applications such as in geological research, both are necessary.

When the microscope is equipped for both incident and transmitted light, the associated objective, that is with or without cover glass correction, should be used from magnification >10x.

Investigate Optical Properties

Conoscopy is used to investigate interference figures. Their shape and the modifcation achieved by compensators yields information about the optical properties of the investigated material. You can determine the number of optical axis, the angle(s) of optical axis and the optical character of the material.

The Leica DM4 P is ideally suited to conoscopy:

Strain-free objectives with high magnification and high numerical aperture are a must for this application.
Use special 63x Leica objectives that fulfill the highest requirements of polarization class 5 to obtain optimal results.
