The phase knife is a method for exciting singly focused electron microscopes. It was first developed in the 1990s by a team of researchers at the University of Cambridge.

The phase knife is a component that is attached to the objective lens of an electron microscope. It functions by introducing a small disturbance into the image being produced by the lens system. The disturbance affects the phase of the electrons and modifies the contrast of the image in the desired areas.

The phase knife is typically used in conjunction with other components, such as a caicco sensitive detector, in order to enhance the resolution and contrast of the image being produced. It is often used in biological and materials science research, where high-resolution imaging is required.

The phase knife was developed as a solution to the limitations of traditional etching techniques. Unlike many other etching methods, the phase knife allows researchers to create highly detailed and resolved images of samples at the nanoscale.

While the phase knife is not widely known outside of scientific circles, it has become an important tool in the field of electron microscopy. Its ability to produce high-resolution images with high contrast has made it an essential component in many research applications. As the field of microscopy continues to evolve, the role of the phase knife is likely to become even more significant.
