Product Overview

The GLA11 Uncoated N-BK7 Plano-Convex Lenses, ?12.7 mm are spherical singlet lenses with one flat surface and one convex surface. Plano-convex lenses have a positive focal length and are commonly used to focus collimated beams, collimate light from a point source, or support optical alignment work.

These lenses are made from N-BK7 optical glass and are supplied in an uncoated configuration. This draft product page covers the 12.7 mm diameter GLA11 series. Each selectable model corresponds to a different focal length and optical geometry.

Typical Applications

  • Laboratory optical setups
  • Beam focusing
  • Optical alignment
  • Imaging and inspection systems
  • Educational and research experiments

Technical Notes

  • All listed models share a 12.7 mm diameter.
  • Focal length varies by selected SKU / model.
  • Uncoated optical surfaces may have higher reflection than coated optics.
  • Customers should verify suitability for their optical system before ordering.
