3 x 1" Rectangular Plane Glass Mirror, 10-Pack

This Eisco Labs pack of 10 rectangular plano glass mirrors is designed for physics and educational use. Each mirror measures approximately 3" x 1" and 2mm thick, with thickness varying slightly between pieces since they are not produced to optical-grade tolerances. Minor cosmetic imperfections may be present and do not affect physical function. Useful for classroom optics experiments involving reflection, image formation, and light-path tracing.
