0.25X SilverTL SWIR Telecentric Lens

Product Details High Resolution f/6 Bi-Telecentric Lenses with Inline Illumination Options Up to 7.5 MegaPixels, 2.8μm Pixel Size Sensors Eliminate Parallax Error in Measurement Applications SWIR Coated Lenses for 900-1700nm Wavelength Range TECHSPEC SilverTL SWIR Telecentric Lenses are designed with broadband AR coatings optimized for a 900 – 1700nm wavelength range. These lenses combine high quality optics with a simplified non-focusing mechanical design and adjustable iris with a locking set screw. For optimum resolution and performance at the application’s target spectral range, SWIR Machine Vision filters and SWIR LED illumination are recommended. TECHSPEC SilverTL SWIR Telecentric Lenses feature a standard front filter thread for use with color filters, polarizers, protective windows, and illumination adapters for LED or fiber-optic ring lights. These lenses are ideal for semi-conductor measuring and both on-line and off-line machine vision production applications that require precise measurements. Note: Mounting brackets are available that fit the 30mm diameter mounting surface.
