Product introduction

The pentagonal prism is one of the beam deflectors with a fixed angle (90°). It has two purposes: one is that no matter what the incident angle on the first surface is, the outgoing light turns the incident light to a fixed angle (90°); the other The second is that it is different from the right-angled building, and the formed image has neither rotation nor specular reflection. The pentagonal mirror is most suitable for image observation systems or measuring instruments. The internal total reflection based on the principle of the critical angle cannot be realized by the pentagonal prism. Therefore, this The two reflective surfaces of floor mirrors are generally coated with metal film and dielectric film.Our standard products are aluminum-coated or reinforced aluminum.
