25mm Dia x 75mm FL VIS-NIR Coated, Illumination Grade PCX Cylinder Lens

Product Details N-BK7 Substrate for Broadband Performance Cost-Effective for OEM Integration Multiple Coating Options Available TECHSPEC Illumination Grade PCX Cylinder Lenses are similar to Plano-Convex (PCX) lenses in profile, but include a portion of a cylinder instead of a sphere. These lenses focus light in one dimension and can transform a point of light into a line. TECHSPEC Illumination Grade PCX Cylinder Lenses are available in circular and rectangular versions, along with multiple coating options. Cylinder lenses are ideal for line projection in machine vision applications or guidance systems. Note: For negative focal length cylinder lenses, see our TECHSPEC Illumination Grade PCV Cylinder Lenses .
