Product Family Description

  • High Resolution f/6 Bi-Telecentric Lens with Inline Illumination Options
  • Up to 7.5 MegaPixels, 2.8μm Pixel Size Sensors
  • Up to 2/3", C-Mount Telecentric Lens
  • Magnification from 0.16X to 4X

TECHSPEC® SilverTL™ Telecentric Lenses are ideal for both on-line and off-line machine vision production applications that require accurate measurements. These lenses combine high-quality optics with a simplified non-focusing mechanical design and an adjustable iris with a locking set screw. These lenses are designed for metrology and gauging applications. TECHSPEC® SilverTL™ Telecentric Lenses also offer inline illumination options for maximum versatility. Each lens also features a standard front filter thread for use with color filters, polarizers, protective windows, and illumination adapters for LED or fiber-optic ring lights.

Note: Mounting brackets are available that fit the 30mm diameter mounting surface.
