Knife-Edge Pickoff Mirrors

Knife-Edge Pickoff Mirrors are designed to selectively reflect an individual beam from a group of tightly spaced beams, while minimizing the overall footprint of the application. These mirrors feature a sharp 45° bevel with a reflective coating that extends to the beveled edge on a precision Fused Silica substrate with λ/10 flatness to the bevel. Knife-Edge Pickoff Mirrors are ideal for applications that incorporate dispersion prisms and diffraction gratings. These mirrors are available in three metallic coating options with performance from the visible spectrum into the far IR.
