Aktiwave can design and lead the fabrication of customized components with spatially varying transmission.

Our components are based on metallic microdots. They can be used as:

• Beam shapers for lasers and incoherent sources
• Spatial masks for projection and illumination systems
• Coronagraphs for telescopes
• Apodizers ("soft-edge apertures")
• Flat-top apodizers ("Gaussian compensating plate")

We can meet your custom transmission with very good accuracy, without symmetry limitations. Furthermore, these shapers are achromatic, do not introduce a wavefront error, and can be AR-coated. We can also design other custom patterns, such as Hartmann masks, checkerboard patterns, sinusoidal patterns, test zones with calibrated transmissions, and test zones with continuously varying transmission.

Pictures of various fabricated parts are shown below. More pictures are available in our Gallery section.
