Product Family Description

  • Finely Threaded Internal Barrel for Fine Focus Adjustments
  • Inner Diameter Baffle Thread for Stray Light Reduction
  • Knurled Lip on Female End for Controlled Adjustments

TECHSPEC® C, S, and T-Mount Fine Thread Focus Tubes are used for making precision adjustments to optical element positions within a system. These tubes feature an outer barrel with male C, S, or T-Mount thread at the base end and a finely threaded interior barrel to allow for fine focusing. The secondary barrel has a female S, C, or T-Mount thread, knurled ring at the front end for easy adjustment, and a threaded interior for light baffle. Set screws can be used to fix the extension position. TECHSPEC C, S, and T-Mount Fine Thread Focus Tubes offer different extension length options to meet specific application demands.
