Johanson-type analyzing crystal achieves perfect convergence.



Shimadzu applied its unique crystal manufacturing expertise fostered through the company's long traditions to offer analyzing crystals that deliver both high sensitivity and high resolution. The Johanson-type analyzing crystal achieves perfect convergence with no aberration.

EPMA-1720 accommodates up to five 4-inch spectrometers that offer both high sensitivity and high resolution.


The Rowland circle radius in the X-ray spectrometer is an important factor affecting the EPMA analytical performance. Increasing the radius of the Rowland circle by one inch reduces the detection sensitivity by more than 30%. Shimadzu EPMA instruments accommodate up to five 4-inch spectrometers to cover the entire spectral range.

Unprecedented Easy Operation Boosts Work Efficiency from SEM Observation to Analysis

The optical microscope image appears on the same monitor as the SEM image. The sensitivity is extremely high.

The SEM image and optical microscope  image are displayed on the same  monitor to minimize shifting
