The EMS model BKPL-211 Microscope replaces the PL-211 and utilizes infinity corrected optics to provide superb image resolution. These strain-free optics and precision engineered mechanisms ensure concentric field of views for accurate specimen identification. Built with user comfort in mind, the BK Series is also built to last, with an all metal focusing mechanism and frame; and all glass condensers for durability to outlast their 5 year warranty. Key features are:
- A rotatable (0-90°) analyzer with slide in/out Bertrand Lens
- Full wave (first class red) and ¼ λ retardation plate compensators; quartz wedge for positioning in condensor
- A precision graduated rotating stage in 1° increments
- Centerable strain-free objectives
Key Specifications
- Optical Body - Seidentopf design inclined 30°; 52-75 mm interpupillary distance
- Eye pieces - WF10X High Eyepoint, FN22
- Objectives - 4X, 10X, 40X, 63X strain-free infinity plan achromatic
- Turret - 4 position ball bearing, reversed for easy access
- Focusing - 0.001 mm markings, adjustable tension control & focus stop prohibits drift, protects specimen and objectives

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

Image Software
Minimum System Requirements:

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
