Optical Manufacturing Capabilities

GIAI Photonics manufactures custom optical components from customer drawings, samples and application requirements. Projects can include optical fabrication, grinding and polishing, edging, coating, inspection and assembly, depending on the component and specification.

Precision optical manufacturing environment

Start With the Optical Requirement

Manufacturing starts with the part specification

The manufacturing sequence is determined by the optic itself. A bandpass filter, imaging lens, prism, infrared window and coated mirror each place different demands on material, geometry, surface preparation, coating and inspection.

For custom work, GIAI reviews the drawing or sample together with wavelength, optical function, dimensions, coating requirements, mechanical interfaces and inspection criteria before the process route is defined.

01 · Function

Optical requirement

Transmission, reflection, focusing, beam splitting, spectral filtering or another defined optical task.

02 · Geometry

Drawing and dimensions

Shape, thickness, edge features, clear aperture and interfaces are reviewed against the intended application.

03 · Process

Fabrication and coating

Grinding, polishing, edging, coating and related operations are selected to match the component definition.

04 · Inspection

Verification

Finished parts are checked against the drawing and agreed optical, dimensional and surface requirements.

Optical Fabrication

From material preparation to finished optical surfaces

GIAI’s optical processing workflow includes material preparation, milling and grinding, precision grinding, polishing, rinsing, edging, coating, inspection and assembly for applicable components.

The exact sequence depends on the optic. Curvature, thickness, edge geometry, clear aperture and surface requirements determine how the part moves through fabrication.

  • Milling and grinding
  • Precision grinding
  • Optical polishing
  • Rinsing and cleaning between process stages
  • Edging and final geometry work
  • Inspection during and after processing

Optical Coating

Coating requirements are defined by the optical system

GIAI provides coating support for filters, lenses, mirrors, windows, prisms and related custom optics. Coating specifications are typically defined by wavelength or spectral band, transmission or reflection target, blocking requirement, substrate and angle of incidence.

Polarization, clear aperture and operating conditions can also be relevant. These inputs allow the coating requirement to be evaluated together with the substrate and component geometry.

Custom Shapes and Drawing-Based Manufacturing

Custom optics from drawings, samples and application requirements

Customer drawings are the preferred starting point for non-standard optical components. When a complete drawing is not available, GIAI can also review supplied samples and application information to identify the parameters needed for a custom project.

  • 2D drawing or 3D reference, where available
  • Material or acceptable material alternatives
  • Operating wavelength or spectral range
  • Critical dimensions and mechanical interfaces
  • Optical surfaces, clear aperture and edge requirements
  • Coating requirements and angle of incidence
  • Inspection or documentation requirements
  • Prototype quantity and expected production demand

Inspection and Metrology

Inspection tied to the drawing and optical requirement

Inspection is part of the manufacturing workflow. Depending on the component, verification can involve optical, dimensional, surface and coating characteristics specified for the project.

Filters are commonly evaluated against spectral requirements, while lenses, prisms, mirrors and windows may place additional emphasis on geometry, surface condition, alignment or other drawing-controlled features.

Optical inspection and metrology
Inspection criteria are defined by the component drawing and optical specification.

Prototype to Production

Support for development, validation and production orders

Quantity and project stage are considered during manufacturing review so that sample work, validation builds and production requirements can be planned against the same approved component definition.

Prototype / SampleEvaluate the part definition, material, coating direction and inspection requirements.
Pilot / ValidationConfirm the approved component configuration and integration requirements before broader production.
ProductionPlan manufacturing and inspection around the approved drawing, quantity and procurement requirements.

Manufacturing Feasibility

Feasibility is confirmed against the actual specification

Material, size, geometry, surface requirements, coating and inspection criteria can all affect the manufacturing route. For non-standard optics, GIAI reviews these details before confirming the production approach.

Key items for review

  • Material and substrate
  • Geometry and critical dimensions
  • Optical performance requirements
  • Coating specification
  • Surface and appearance criteria
