Optical Custom Design

Kire Optronics delivers OEM optical customization for global customers, supporting projects from requirement alignment and prototyping to pilot builds and volume production. We focus on manufacturability, consistency, and scalable delivery, providing practical engineering support and controlled processes for repeatable performance.

What We Can Customize

Optical Components

Lenses (spherical/aspherical/cylindrical/achromatic cemented lenses), windows (optical & protective), prisms (right-angle/roof/penta/Dove/corner cube/wedge, etc.), mirrors, beam splitters, and PBS prisms.

Filters & Coatings

Bandpass/narrowband, longpass/shortpass, ND filters, and functional thin-film coatings such as AR/HR and beam-splitting coatings (specified by wavelength, AOI, polarization when applicable).

Optical Lenses (Lens Solutions)

Imaging lenses and lens assemblies for consumer imaging, industrial inspection/machine vision, security monitoring, automotive optics, and infrared applications (project-based support for fixed-focus/zoom, low distortion, wide-angle/fisheye, ToF, etc.).

Assemblies

Bonding and assembly support, optical axis alignment, and project-based module delivery with consistency control.

Optical Systems

System-level collaboration for optical subsystems (imaging/projection/illumination/splitting/filtering, etc.), supporting specification alignment, prototype validation, and pilot-to-volume ramp-up based on project scope.

Materials We Support

Schott, Hoya, Ohara, CDGM optical glass; optical crystal; Corning fused silica; Si; Ge; Sapphire; CaF2 optical crystal, etc.

Manufacturing Scale & Delivery

Production range (reference):

φ3–φ50 mm
(especially strong in φ5–φ28 mm)

Monthly capacity:

over 1.5 million pieces
(product-mix dependent)

Batch size:

3K–500K pieces per batch (project-dependent)

Quality, Traceability & Packaging

Consistency is built through defined control points, appropriate metrology/inspection, in-process verification, and shipment inspection. Traceability can be established across materials, process steps, inspection records, and shipment batches based on project requirements.

• Quality Control

Project-based traceability for quality and delivery control

• Packaging

Dust-free vacuum packaging to protect optical surfaces during storage and transport

Typical Production Capability (reference)

Specifications vary by project. Below is a representative reference level for OEM optical components:

Specifications (Reference)	Reference Level
Diameter tolerance (reference)	±0.01 mm
Surface figure (reference)	0.25 λ/inch
Surface quality (reference, S/D)	40–20
Centration (reference)	15″

How To Start

Share drawings/specs (or samples), target quantities, and timeline

We confirm requirements and propose a manufacturing route (DFM-focused)

Sampling and validation (fast iteration when needed)

Pilot build and quality criteria alignment

Volume production and long-term supply support

What to include for a faster quotation

◈ Drawings/specifications (or sample photos) and key dimensions
◈ Material preference and coating requirements (wavelength, AOI, polarization if applicable)
◈ Application scenario and key performance targets
◈ Target quantities (prototype / pilot / volume) and delivery timeline
◈ Any acceptance criteria or inspection requirements
