Product Family Description

  • Up to 1/1.8", C-Mount Lens
  • Up to 12 MegaPixels, 1.85µm Pixel Size Sensors
  • Ultra-Compact (UC), High Resolution Lens for Small Sensors
  • 4mm to 35mm Focal Length

Our ultra-compact, TECHSPEC® UC Series Fixed Focal Length Lenses are designed to optimize performance, cost, and size without sacrificing quality or feel. Designed for pixels that are ≤2.2μm, these lenses provide high levels of resolution (>200 lp/mm) across the sensor and are compatible with all standard C-Mount cameras. TECHSPEC® UC Series Fixed Focal Length Lenses feature focus and iris adjustments, as well as recessed set screws, and are manufactured for use at typical machine vision working distances. While they are optimized for 1/2.5" sensors, many focal lengths will work on sensors up to 1/1.8". The TECHSPEC® UC Series Fixed Focal Length Lenses are an outstanding option for use on all smaller format camera sensors, along with both short and long working distance applications, making them ideal for inspection, factory automation, biomedical devices, and a broad range of other applications.

Note: For fixed aperture instrumentation versions, see our TECHSPEC® UCi Series Fixed Focal Length Lenses.
