0.28X CobaltTL Telecentric Lens

Product Details High Resolution Bi-Telecentric Lens with In-Line Illumination Options Up to 20 MegaPixels, 2.2µm Pixel Size 1.1″, C-Mount Telecentric Lens with f/#’s as Low as f/4 TECHSPEC CobaltTL Telecentric Lenses are designed for semiconductor and electronics inspection, measurement, and gauging applications. These telecentric lenses achieve high light throughput with industry leading low f/#s. Featuring less than 0.015° telecentricity and low 0.013% distortion, these lenses are ideal for image stitching applications. These 17.6mm diagonal sensor format lenses are compatible with the Sony IMX304 1.1” sensors and other similar format sensors such as the Sony IMX183. TECHSPEC CobaltTL Telecentric Lenses produce unparalleled levels of contrast yielding maximum image quality with the highest degree of measurement accuracy. In-line versions provide the ability to rotate/reposition the inline illumination port to allow for maximum flexibility when machine building. TECHSPEC CobaltTL Telecentric Lenses are compatible with high vibration environments and feature a removable recessed set screw for securely locking the iris in place.
