Interview with Magdalena Banko, President of Princeton Scientific Corporation.

Easy Engineering: What are the main areas of activity of the company?

Magdalena Banko: We are a leading supplier of high-quality, high-purity, single crystals of rare earth, transition and refractory metals and alloys. Our Material Product Line is viewable at

We also supply precision and diamond wire saws, plasma cleaning systems, ultra-high vacuum technology and accessories, and particle beam line systems. 

E.E: What’s the news about new products?

M.B: The WS-25B is the newest high precision wire saw in our product line. This unique saw can cut using the free abrasive method (wet cut), as well as cut using diamond dotted wire (dry cut). The WS-25B, in addition to the other saws in our precision wire line are viewable online.

Our Kelvin Probe system allows precise measurement of the work function of different semiconducting and conducting materials with high precision and accuracy. View more about our Kelvin Probe system here:

E.E: What are the ranges of products?

M.B: We have an excellent and long-standing reputation for Metallic Single Crystals, Sputtering Targets, Superconductor substrates, Laser Crystals, Optical Materials, Opto-Electronic Components, and various Oxide Crystalline Materials within the scientific community. 

Not only do we offer crystal boules, blanks, semi-finished and finished products in the form of wafers, windows, lenses, prisms, tubes, rods, and crucibles, but we also provide cutting and polishing services for such materials.
