Recubrimiento Óptico para Lentes de Vidrio: Consideraciones de Diseño y RFQ

An optical coating request should connect the required spectral performance with the actual glass component, its operating environment and the agreed inspection method. A short request such as “AR coating required” leaves important questions unanswered. Clear input at the RFQ stage helps the coating and component teams review feasibility, measurement conditions and acceptance criteria together.

Define the optical requirement first

Start with the wavelength or wavelength range, the desired transmission or reflection behavior and the angle of incidence. If performance is required at more than one angle or polarization state, state this explicitly. The drawing should also identify the coated surface and the clear aperture where the requirement applies.

System-level context is useful when a single numerical target does not fully describe the function. Tell the supplier whether the component is used for imaging, detección, illumination, filtering or another optical task.

Identify the glass substrate and component geometry

The coating review depends on the substrate as well as the spectral target. Provide the glass type, supplier designation when controlled, part dimensions and surface geometry. Curved surfaces, small clear apertures, edge features and handling restrictions may affect tooling, masking and inspection.

If the glass component is also being manufactured for the project, coordinate the drawing and coating specification with the glass optical manufacturing requirements. This reduces ambiguity between component and coating acceptance.

Describe the operating environment

Temperature, humidity, cleaning methods, abrasion risk and exposure to chemicals can influence the coating review. State whether the optic will be sealed inside an assembly or exposed during regular use. Any durability or environmental test should include the required method and acceptance condition.

When a customer specification or recognized test method applies, identify its revision and the sections relevant to the component. This gives both teams a common reference for planning and validation.

Separate spectral and cosmetic requirements

Spectral performance and visual appearance are different acceptance areas. The RFQ should define how optical performance will be measured and which zones are cosmetic. Mark the clear aperture, edge allowance and any surfaces that must remain uncoated.

Cosmetic criteria should be stated on the drawing or in an attached specification. Avoid relying on an informal sample description when a measurable or documented acceptance method is available.

Agree on inspection and reporting

Specify the measurement range, angle, polarization condition and sampling expectations that apply to the coating. If a spectral report, dimensional report or other quality document is required, include it in the RFQ. Witness samples should be discussed in advance when the production component cannot be measured using the same method.

The Silver Optics quality assurance page explains why drawing requirements and inspection expectations should be agreed before production.

Coordinate coating with handling and assembly

Coated optics need suitable handling, cleaning and packaging instructions. Critical surfaces should be protected through inspection, transport and assembly. If the component will be bonded, mounted or assembled after coating, identify the relevant contact areas and any restrictions in the drawing.

For projects that combine component manufacturing and coating, review the process sequence with the optical coating team before finalizing the specification.

Frequently asked questions

What information is needed beyond “AR coating”?

Include the substrate, wavelength range, angle of incidence, spectral target, coated area, environment and inspection method. These inputs define what must be reviewed and measured.

Can the same coating specification be used for every glass type?

The substrate is part of the coating review. Always identify the actual glass type and component geometry so the supplier can evaluate the complete requirement.

When should cosmetic criteria be defined?

Define them before quotation and sample approval. Mark the clear aperture and cosmetic zones, then state the inspection method or referenced specification used for acceptance.
