telecentric lens TV-F series Magnification-switchable object-side telecentric lens

overview

  • A single lens allows you to switch between two magnifications
  • When changing magnification, the working distance does not change.
  • When the magnification is changed, the effective F-number does not change.
  • Magnification within the depth of field remains unchanged
  • WD=115mm, 130mm, 156mm, 220mm, 290mm series
  • ×0.5~×1.0, ×1~×2, ×2~×4
  • One straight model and nine coaxial incident type models available
  • Coaxial epi-illumination type realizes uniform illumination light
  • low optical distortion
  • VGA camera compatible model
  • Low cost
  • Compatible with 1/2" cameras
  • C-mount

  • *The maximum outer diameter excludes the dimensions of the coaxial incident part.

Illumination direction and magnification operating pin position relationship

When ordering, please choose from the following four types: A, B, C, and D. If no preference is given, type A will be used. Example: For TV1020-115-F and type B, choose TV1020-115FB.
