Elliptical Mirror 57.15mm Minor Axis Protected Silver

Product Details See Figure B in Technical Information tab for dimensional diagram. Circular Profile When Oriented at 45° Ideal for Redirecting Light Multiple Sizes and Coatings Offered TECHSPEC λ/8 Precision Elliptical Flat Mirrors are ideal for research and astronomical applications. Because of their elongated major axis, they are suited to bending and folding light at precise angles with minimum wavefront distortion. These mirrors have a circular profile when they are oriented at 45º. TECHSPEC λ/8 Precision Elliptical Flat Mirrors feature a BOROFLOAT substrate. Multiple sizes and coating options are offered to best suit a wide range of applications.
