The Imaging Source has introduced the TBN 1.98, a lightweight and cost-effective S-mount lens designed for machine vision applications requiring extremely wide-angle shots. This new lens delivers superior image quality and a significantly expanded field of view.

Key Features and Benefits

  • Wide Field of View: The TBN 1.98 boasts a 118° field of view, allowing imaging systems to capture a larger area – potentially reducing hardware costs.
  • Low Distortion: The lens exhibits very low distortion, as demonstrated in the comparison images below.
  • Compact Design: Weighing only 7 grams, the M12 lens is ideal for space-constrained applications.
  • Visible Light with IR Cut Filter: The lens is optimized for visible light and includes an IR cut filter.

Comparison Images

The following images illustrate the difference in distortion between the TBN 1.98 and other S-mount lenses:

  • TBN 1.98 vs. TBL 2.9: This comparison highlights the TBN 1.98’s ability to minimize distortion, even at a distance of 135 mm and a field of view of 390 mm. The TBL 2.9, a standard S-mount lens, shows significantly greater distortion.
  • TBN 1.98 vs. TBL 8: The TBN 1.98 offers a 118° FOV, while the TBL 8 (8 mm lens) provides a smaller FOV of approximately 100 mm. Although the TBL 8 exhibits lower distortion at 135 mm, it lacks the large field of view of the TBN 1.98.
