Nanobeam diffraction of GaN/InGaN
This gallium nitride/indium gallium nitride (GaN/InGaN) quantum well structure is popular in the fabrication of LED products. The OneView camera enables users to record diffraction pattern movies using the in-situ mode option. See original sample labeled [110] high resolution image of GaN/InGaN in the OneView media library.
OneView IS particle tracking, part 2
The OneView IS particle tracking feature lets you define the area of interest, then automatically maintain that area in the center of your display while collecting in-situ data. This movie was taken with Track Particle feature on, allowing the particle of interest to stay stationary in the field of view. See OneView IS particle tracking, part 1 video in the OneView media library to compare the particle movement in the original dataset.

The OneView IS particle tracking feature lets you define the area of interest, then automatically maintain that area in the center of your display while collecting in-situ data. See OneView IS particle tracking, part 2 video in the OneView media library to compare how the particle of interest stays stationary in the field of view when the Track Particle feature is on.
OneView IS post-processing and frame alignment
In-situ results are best viewed in a movie format, but, depending on the number of frames chosen to sum throughout the stream, data can suffer from blurred detail caused by the drift or shift between each image. This video demonstrates how the OneView camera can average 5 frames using the frame alignment function during post-processing. As the sample drifts, averaged frames stay sharp to attain high-resolution results.
Zeolite catalyst
Chevron SSZ-57 zeolite (4k x 4k)
Some samples, like this zeolite catalyst, are so beam sensitive that they are distorted and destroyed quickly under the electron beam. This makes it nearly impossible capture a good image. This video acquired using the OneView camera demonstrates how the fast image acquisition rate combined with live drift correction, delivers a sharp, high-resolution image.
