Component Specifications

Definition
Mounting threads are specialized threaded components designed to secure optical lenses within barrel assemblies through precise helical engagement. These threads provide both mechanical fixation and precise axial positioning, ensuring optical alignment within tight tolerances (typically ±5-10 microns). They feature controlled pitch, lead accuracy, and thread form optimization to minimize stress concentration and maintain dimensional stability under thermal and mechanical loads.
Working Principle
Operates on the helical inclined plane principle, converting rotational torque into precise linear displacement to position and secure optical elements. The thread geometry creates controlled preload distribution, maintaining lens alignment while allowing for adjustable focus or replacement through controlled rotation.
Materials
Stainless steel (AISI 416, 17-4PH), aluminum alloys (6061-T6, 7075-T6), or titanium alloys (Ti-6Al-4V) with surface treatments: black oxide coating, passivation, or nickel plating for corrosion resistance and reduced reflectivity.

  • Pitch 0.35mm to 1.5mm
  • Thread Type Unified Fine Thread (UNF) or Metric Fine
  • Concentricity ≤ 0.01mm TIR
  • Thread Runout ≤ 0.005mm
  • Diameter Range M4 to M30
