Industry Application
Machine Vision For Display Glass and Film
Transparent and semi transparent web material where the defect you are looking for transmits almost as much light as the good product around it.
Industry Pain Points
Why These Parts Are Hard To Image
- Glass is transparent and highly reflective at the same time, so a single lighting angle rarely works.
- Internal foreign material and tiny bubbles only appear under controlled dark field or bright field conditions.
- Film moves fast and continuously, so illumination has to be uniform across the full web width.
- LCD and OLED panels show mura and scratches that depend entirely on the angle of incidence.
Customer Requirements

How A Project Runs From Enquiry To Delivery
Send The Part And The Target
A photo of the part, the defect you need to catch, the field of view and the line speed.
Lighting And Optics Proposal
Our design engineers propose a lighting geometry, a lens format and a camera that hold together as one chain.
Sample Or Custom Build
Standard parts ship from catalogue. Custom lighting samples are normally provided within 10 working days.
Validation On Your Part
You prove the image on the real part. Where the geometry needs changing, the design is revised before volume.
Supply And Repeat Orders
Once the model is fixed, repeat orders reference the same model number and the same imaging result.
Delivery Capability
What We Commit To
- More than 20 experienced customized design engineers for lighting and optics design.
- Most customised products provided within two weeks.
- Urgent customised demand shortened to around five days.
- Customised lighting samples normally provided within 10 working days.
- Most focal lenses shipped within three days.
- Lending samples for test available on the telecentric line scan lens range.
