When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Fig. 1 | (a) The sketch of the PDSM-241. (b) Actuator layout (clear aperture: 270mm). (c) The self-corrected aberration of PDSM-241. A new publication from Opto-Electronic Advances, ...

Optical Surfaces Ltd. is a leading international manufacturer of large diameter, ultra-smooth off-axis parabolic mirrors for demanding applications. Looking to develop their next generation of ...

The Abbe diffraction barrier, which fundamentally restricted the lateral optical resolution to 200 – 300 nm until the early 1990s, can be overcome by super-resolution optical fluorescence imaging ...

The gem 561 laser from Laser Quantum provides up to 1000 mW of yellow light in a near diffraction-limited TEM00 beam with an M²<1.2. The gem 561 can be easily integrated into OEM applications and has ...

[Diffraction Limited] has been working on a largely 3D-printed micropositioner for some time now, and previously reached a resolution of about 50 nanometers. There was still room for improvement, ...

Accelerator-based high-energy electron diffraction determines 3D atomic structure of materials New method using ultrashort ...
