## Description

At the United States Military Academy, cutting-edge research in laser and photonics systems has long relied on high-precision quarter-wave plates to enable advanced manipulation of light polarization; historically, these waveplates have been used to impart precise 90° phase shifts that convert linearly polarized light into circular or elliptical forms—a transformation critical for in-depth studies of birefringence, polarization-dependent losses, and laser beam shaping.

Cadets will use quarter-wave plate engineered for 780 nm applications, ensuring that their research continues to push the envelope in optical performance and innovation, which is essential for both educational and defense-related technological advances. minimum specifications:

**Retardation:** ?/4 Diameter: 25.4 +/-0.25 mm Thickness: <2 mm Operating wavelength: 780 +/- 10 nm Reflectivity: <0.5%
