Product Family Description

  • Focusable to Allow for Working Distance Adjustment
  • High Light Throughput f/6 Designs
  • Designed for ½” and 2/3” Sensor Formats
  • <0.2° Telecentricity

TECHSPEC® GoldTL™ Telecentric Lenses were designed specifically for machine vision and metrology applications. The unique focusable design allows for working distance adjustment, while still providing <0.2° telecentricity. These lenses also feature high resolutions, low distortions, and are available for ½” or 2/3” sensors. TECHSPEC® GoldTL™ Telecentric Lenses have a front filter thread for easy integration of color filters, polarizers or other mounted components. Both the iris and focusing adjustment positions can be fixed by set screws to remain secure in high vibration environments.
