Opton Laser commercializes ultra-high contrast third-order autocorrelators

Of the three primary stepper motor designs — permanent magnet, variable reluctance, and hybrid — hybrid stepper motors are arguably the most popular in industrial applications, combining the best performance characteristics of permanent magnet and variable reluctance types.Hybrid stepper motors are constructed with a rotor made of two sections, or cups, with a permanent magnet between ...

In the U.S., one in five of the 37 million adults who has diabetes is not aware of it (according to the U.S. CDC – Centers for Disease Control & Prevention). Current methods of diagnosing diabetes and prediabetes usually require a visit to a doctor’s office or lab work, both of which can be expensive and time-consuming. Now, diagnosing diabetes and prediabetes may be as simple as breathing. ...
