Custom optical components
From your requirement
to a defined optical solution.
Start with a drawing, a sample, a specification or a design objective. PHOSLENS coordinates technical review and custom production with manufacturing partners.

Four ways to start
Your starting point. Our next step.
You do not need a catalogue model to begin. Choose the route closest to your project; the technical scope and acceptance criteria are confirmed before production.
Manufacture from your drawing
Send the component drawing and revision. We review the material, geometry, tolerances, optical finish and coating requirements for manufacturability.
- Dimensions, clear aperture and edge details
- Surface quality, figure and coating specification
- Quantity and agreed inspection requirements

Reproduce from a physical sample
A sample can be the starting point for measurement and reproduction. We assess the geometry and identifiable optical characteristics, then agree the target specification.
- Sample assessment and critical dimensions
- Material and coating verification where required
- Prototype comparison against agreed criteria
Customize from your parameters
Provide the optical and mechanical requirements you know. We help identify missing information before reviewing a suitable manufacturing route.
- Material, diameter, thickness and focal length
- Operating wavelength, coating and environment
- Quantity, application and target performance

Develop the design with us
Start with the application and performance objective. Design support can help turn your requirements into an optical concept and a component specification for review.
- Application, wavelength and optical layout
- Mechanical envelope and interface constraints
- Design scope, deliverables and validation plan
For sample reproduction, “1:1” means a target agreed after assessment. Geometry alone does not establish the original material, coating or optical performance. Final tolerances and performance must be confirmed for the project.
From input to delivery
A clear custom optics process.
A drawing or a sample gives us a starting point. Specifications and design objectives follow the same review path.
Share the requirement
Tell us the application, quantities and available inputs. Contact us before sending a physical sample.
Review feasibility
Review the drawing or sample, clarify missing parameters and identify the appropriate technical route.
Confirm scope & quote
Agree specifications, drawing revision, inspection criteria, pricing and project-specific delivery terms.
Prototype & manufacture
Proceed with the agreed design or production scope. Confirm any prototype approval stage in advance.
Inspect & review
Check the component against agreed requirements and review any inspection documents specified in the order.
Pack & deliver
Arrange suitable packaging and delivery under the confirmed terms, with follow-up for project requirements.
Manufacturing partner network
Connect the specification to the process.
Discuss custom geometry, materials, optical finishing and coatings for lenses, prisms, windows, mirrors and related components. The production and inspection route depends on your specific requirement.



Photos show cooperating manufacturing facilities and example optical components. Equipment photos do not establish a particular precision, certification or capacity; these are reviewed for each project.
Start a custom project
Tell us what you need.
A short description is enough to start the discussion. Include the quantity, application, dimensions, material and wavelength where known.
Have a drawing or data file?
Submit the description first, then email your files with the inquiry reference. We will confirm sample-shipping arrangements separately.
