Optical dicing refers to precision cutting processes used to segment optical materials, particularly those with specialized coatings, into smaller functional components while maintaining their structural and optical integrity. In the context of optical coating flats (flat substrates like glass, fused silica, or semiconductors coated with anti-reflective, dielectric, or other optical layers), dicing ensures these coated substrates meet exact dimensional requirements for applications in photonics, lasers, sensors, and semiconductor devices.

Methods

  • Saw Dicing: Diamond-coated blades for clean cuts with minimal chipping.
  • Laser Dicing: Non-contact ablation for delicate or brittle materials, reducing mechanical stress.
  • Plasma Dicing: Dry etching for ultra-fine features, ideal for advanced semiconductor wafers.

Price

Dicing Service will generally cost from $50 to $125 per piece. Depending on the accuracy and size you are requesting.

Fequently Asked Questions

What are the Thickness of the Optical Filters?

For Mounted Optics:

  • 6mm (by Default)
  • 3.5mm (Specified in Order Note)

For Unmounted Optics:

  • 0.5mm
  • 1.1mm
  • 2mm

(most of the unmounted optics are having thickness of 1.1mm ~ 2mm)

What is the difference between mountings?

Unmounted:

  • a bare glass optical filter

Mounted:

  • Smooth Mount for protection of the optics. No thread is there on the mount.

Metric Mount:

  • Start with M as prefix, usually seens as M25.5x0.5mm. Mostly used as camera filters

Imperial Mount (Usually Thorlabs):

  • Start with SM as prefix, usually seen SM1, SM05 etc... Mostly used in Optical system. (You will have a SM external thread to connecting to other objects)

C-Mount:

  • Very frequently used mounting. C-Mount is 1‘’-32TPI. And it is not the same thing as SM1, or M25.5x0.5mm.

Standard Mountings
