50mm Dia x -400mm FL, Protected Aluminum, Convex Mirror

Product Details Precision Polished Surface λ/2 Surface Accuracy Variety of Coating Options Offered TECHSPEC Convex Mirrors are ideal for expanding an imaging system’s field of view without introducing chromatic aberrations. TECHSPEC Convex Mirrors utilize a precision polished surface with a λ/2 surface accuracy to maintain image quality. These optical mirrors create virtual, upright images. Shorter focal lengths generate wider fields of view, while longer focal lengths minimize distortion.
