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.
