I would offer this is the only company I will do business with regarding Class 4 Laser safety. Their service is second to none. Regarding the acrylic face shield only, and its protection, this is absolute. The hardware metal screws are of a poor grade and sheared in half. The controls to elevate the face shield, will not properly hold the face shield elevated, and all plastic components, excepting the acrylic face shield, component plastic used, is some sort of possible styrene and not acceptable for this application . I wear their CE protective goggles in the 445 NM in the event the unit fails, and if you do, the face shield has merit in Class 4.

Screws: This issue is unprecedented for us, but we value your feedback. We will expedite the dispatch of replacement screws. Please contact us to arrange this. Elevation Mechanism: We're interested in understanding the specific issue you've encountered to ensure it doesn't happen again. We'd appreciate the opportunity to discuss this further and find a solution.

Expect excellent service and certifications sent on each pair of specific lenses to the end user client. You cannot get a second chance with high intensity lasers and your eyes. I absolutely trust this firms product, their certifications and their excellent service.

Polarizationof light notes PDF

The phenomenon in which electromagnetic waves, such as light waves, vibrate in a preferred plane or planes; or the process of confining the vibrations to certain planes. In unpolarized light the vibrations are equally distributed in all directions perpendicular to the direction of propagation of the wave. If all the vibrations are confined to one plane, the light is said to be plane-polarized (or linearly polarized). If the light in one plane is out of phase with the light in the plane at right angles to it (i.e. if the peaks and troughs of the waves are not in step), then the light is said to be circularly polarized. If all these phenomena occur together, the light is said to be elliptically polarized. Plane polarization is usually caused by scattering, and circular polarization by strong magnetic fields. Circularly and elliptically polarized light can also be produced by a wave plate. See also stokes parameters.

Thank you for your review. We're pleased to hear that our service has met your expectations. Regarding your experience with the face shield:

Please note that our face shield design is functionally similar to those available from industry leaders like Pyramex, Grainger, 3M, or at hardware stores, differing primarily in the addition of the laser safety component, which is our unique value proposition.
