Spherical Lenses

 

Versatile, Precise Spherical Optics

Spherical lenses are anything but simple. Convex and concave lenses must be crafted for predictable, reliable performance with uncompromising quality.

When you choose LaCroix, your project benefits from our design-for-manufacturability principles. DFM gives your project team the freedom to design and manufacture converging and diverging lenses in the most efficient and cost-effective way, from prototype to high-volume production.

Spherical Lens Manufacturing

Spherical lens fabrication begins with a LaCroix Manufacturing Engineer dedicated to seeing your project from sketch to completion.

We follow a step-by-step process with rigorous quality checks along the way. 

  1. Optical Design: You'll work together to design the lens to spec, then production begins with a near-net-shape optical glass blank.
  2. Shaping, Grinding: Diamond ring tools generate the radius into the glass blank. A series of progressively smaller grit diamond wheels or loose abrasive material finely grinds the lens blank.
  3. Polishing: Pitch or polyurethane pads and a cerium oxide slurry finish the spherical lens surface.
  4. Test and Measurement: Interferometry, surface roughness, radius of curvature, aberrations, and more.
