Precision Optics for Custom Applications
Giai Photonics Co., Ltd. designs and manufactures precision optical components, including optical filters, multi-element lenses, and coated optics, supported by engineering, optical fabrication, and metrology.
GIAI also works with optical lenses, prisms, mirrors, beamsplitters, optical windows, infrared optics, and other components used to transmit, reflect, split, focus, or redirect light within optical systems.
For custom projects, customers can send a drawing or sample together with the available wavelength, material, dimensional, coating, application, and quantity requirements.
Precision Optical Components
GIAI supplies optical components for filtering, imaging, beam control, infrared, coating, and custom optical applications.
Optical Filters
Wavelength-selective optical components for transmission, blocking, attenuation, and spectral control requirements.
Optical Lenses
Lens components used to focus, collimate, collect, or otherwise control light inside imaging and optical systems.
Optical Prisms
Prism geometries used to redirect, reflect, disperse, or divide light according to the optical-path requirement.
Mirrors & Beamsplitters
Reflective and beam-splitting components used to direct or divide light within an optical assembly.
Optical Windows
Flat optical elements used where transmission and protection of an optical system must be considered together.
Infrared Optics
Infrared optical components using materials selected for the required wavelength region and system function.
Optical Coatings
Coating requirements integrated with filters, lenses, mirrors, windows, prisms, and other optical substrates.
Custom Optical Components
Customer-specific optical work based on drawings, samples, spectral requirements, geometry, and application needs.
Start with Your Optical Requirement
A custom optics project usually begins with the function of the component inside the optical system.
Depending on the project, that may mean defining a wavelength range, transmission or reflection target, blocking requirement, optical material, coating, geometry, dimensions, or the mechanical constraints around the optic.
If a drawing is available, send it with the inquiry. If the project starts from an existing component or sample, include the application and the changes you need.
From Optical Design to Manufacturing
GIAI combines engineering, optical fabrication, lens and prism processing, coating, and metrology in its optical-component work.
Custom components begin with optical and mechanical requirements that must be carried through fabrication, coating, and inspection.
Tolerances, coating targets, materials, and acceptance criteria are defined for the individual component and project.
Engineering Review
Clarify the component function, drawing, material, geometry, coating, and other relevant requirements before production decisions are made.
Optical Processing
Connect fabrication and coating work with the requirements defined for the specific optical component.
Inspection
Evaluate the finished component against the requirements agreed for the project or order.
Quality Control and Inspection
A finished optical component is useful only when its relevant characteristics match what the optical system requires.
That makes specification review and inspection part of the same technical path. Depending on the component, the requirements may involve spectral behavior, material, dimensions, geometry, coating, or other drawing-defined characteristics.
Inspection methods and acceptance criteria are selected according to the requirements of the individual optical component.
Verify the finished optical component against the requirements agreed for the project.

A Message from Lin
When GIAI was established in 2008, our direction was straightforward: build a company that could take an optical requirement and turn it into a component that works in the customer’s actual system. That remains the way I think about our business today.
In custom optics, the useful conversation usually starts with the details. A drawing, a sample, a wavelength range, a coating target, a dimensional requirement, or simply an explanation of what the component needs to do can change the way a project should be approached. I want our team to understand those details before we talk about production.
Over the years, GIAI has continued to develop its work around optical fabrication, coating, and inspection. For me, these are not separate steps. They are parts of the same responsibility: the finished component should be made and checked against the requirements agreed for the project.
I also believe that good cooperation is built through clear communication. Customers should be able to discuss technical questions with us, understand what information is needed, and receive practical feedback when a specification needs further clarification. Some projects begin with a complete drawing; others begin with an existing sample or an application problem. Our role is to help move that information toward a manufacturable optical component.
As GIAI continues to grow, I want us to remain focused on the fundamentals: understand the requirement, respect the specification, manufacture carefully, inspect what matters, and build relationships that can continue beyond a single order.
How We Approach Custom Optical Work
- Start
- Review the drawing, optical specification, application requirement, or existing sample available for the project.
- Define
- Clarify the optical function, material, dimensions, geometry, coating requirements, and acceptance criteria that matter to the part.
- Make
- Plan the fabrication and coating route around the actual component rather than a generic process description.
- Verify
- Inspect the finished component against the requirements established for the project.
