Leica DM2700 P
This polarization microscope combines high-quality Leica optics with state-of-the-art universal white light LED illumination for the incident and transmitted light applications. Because of its flexibility, the Leica DM2700 P meets the needs of both basic to advanced examinations where high-quality polarization equipment is required.
With a wide range of accessories, it is the ideal inspection tool for all kinds of routine inspection tasks in earth sciences, the plastic and polymer industry, liquid crystal inspections, and furthermore.
The options of this versatile instrument not only fulfill many application requirements but also the budget.
- Five-Position Centerable Nosepiece
The Leica DM2700 P offers, unique, for this class of microscope, a five-position center able nosepiece. It can equip the microscope with different objectives for specific tasks.
- Strain-Free Objectives Designed for Your Application
For reliable investigations of birefringence materials, Leica Microsystems offers a wide range of polarization objectives. Select from a variety of objectives designed for qualitative and quantitative polarization.
- Flexible Conoscopy
Choose a conoscopy module that adapts to your application and budget:
- The advanced module with center table, focusable Bertrand lens; pinhole; and an extended field of view is ideal for transmitted light and incident light microscope configurations.
- Two standard modules with center-able, focusable Bertrand lens or pre-focussed Bertrand lens only, built-in analyzer, and integrated pinhole, are suitable for transmitted light microscope configurations.
- The Bertrand lens cube is a center table and is pre-focused for microscope configurations with an incident light axis.
- LED Illumination
Ultra-bright, high-power LED illumination provides a constant color temperature of 4500º K for the incident and transmitted light illumination methods. It offers real color imaging at all intensity levels without the need for additional filters. With a long lifetime and low power consumption, LEDs have enormous savings potential.
