Polarized and Metallurgical Light Microscopes

Polarized Microscope for Petrology

Polarized Investigations made Easy

The EMS Polarizing Microscope is an excellent tool for Petrography and other mineral or earth science applications. Observation and analysis is easy with strain-free optics and polarizing mechanisms that ensure concentric field of views and accurate identification. Built with user comfort in mind, the PL series is also built to last, with an all metal focusing mechanism, all metal frame and all glass condenser that will outlast the 5 year warranty. Key polarization features of models PL-211 and PL-311 Trinocular include:

• A rotatable (0-90º) Analyzer with slide in/out Bertrand Lens
• DIN standard full wave (first class red) and quarter wave compensators and quartz wedge with slide stops for positioning in the Analyzer
• A precision rotating stage graduated in 1º increments and a swing out polarizer
• Four strain-free objectives, each centerable, mounted on a rear facing four poisition turret

Metallurgical Microscopes

For Materials Analysis and more

EMS Metallurgical Microscopes use long working distance objectives and reflected or incident illumination to deliver sharp, high contrast images of solid specimens. The large collector lens and light path combine with the specifically positioned diaphragms to allow more light for brighter images. A polarizer and analyzer and color filters are built-in to enhance observation. The Inverted model utilizes incident illumination for over size samples. The trinocular head allows for quick and easy attachment of cameras for documentation.

• Five long working distance objectives without cover slip correction for close specimen observation
• Transmitted illumination is facilitated with large glass inserts in the mechanical stage
• The polarizing analyzer is used in conjunction with the polarized filter cube, which is easily accessed via the push rod. The analyzer may also be placed on the lower light source and used with the polarized filter cube for transmitted light work.

Key Specifications

• Optical body - Seidentopf design inclined 30°; 55 to 75 mm interpupillary adjustment, 360° rotation
• Nosepiece - quintuple, ball bearing
• Eye pieces - 10X, Focal Length 25mm, FN 18 mm.
• Focus mechanism - adjustable tension control to prohibit drift and adjustable up-stop to protect objective lenses; dial markings at 0.002mm increments
• Incident light system includes: condenser, iris diaphragm, color and polarizing filter. Transmitted illumination, 1.25 N.A. Abbe condenser with iris diaphragm; all systems use a 20 watt, 6 volt Halogen bulb with dimmer

Camera Systems

We offer three types of camera systems for documenting resolved microscopic images.

Each system is fully integrated with:

• software for image analysis
• optical adapters to obtain the image in the correct focal plane
• cables for connection to computers, monitors or projectors

All components are conveniently packaged under one part number for easy ordering

Image Software

Minimum System Requirements:

1. Microsoft Windows 98, ME, 2000, or XP. This software will not operate on Windows NT
2. A CD-ROM Drive to install the software.
3. An Ethernet Card for the license.dat file to identify (Software requires a License file to operate)

Jenco Image is a software tool for microscope image measurement. †It captures or imports and archives database images and allows image annotation, Email links, or report generation. †It can be used to measure point to point or multi-pointed lengths/distances and/or area of: lines, angles, circles, rectangles and ellipses in the captured image with calipers in metric, English or pixels. The system can also calculate a color area and percentage of color relative to the whole. The system can be calibrated to scale/magnification so the result of the measurements and virtual values will keep a 1:1 relation. †All results can be saved in the computer for further research.

• Point-to-point linear measurement
• Radius and diameter on ellipse
• Area and perimeter for ellipse or rectangle
• Length of segmented lines
• Area and perimeter of irregular shapes
• Angle measurements
• Arc/Ellipse/Circle measurements including definition of center point, chord lengths, sweep angles, radii, and more
