Micro Penta Prism (Five-Sided Prism)
Our Micro Penta Prisms are precision-fabricated from high-quality N-BK7 (or UV Fused Silica) with leg dimensions starting from 1.0 mm, designed to deviate an incident beam by a fixed 90° through two internal reflections—without inverting or reverting the image. Unlike right-angle prisms or mirrors, the 90° deviation is insensitive to minor prism rotation, making it ideal for optical alignment, aut
