| Production Process |
Photosensitive Ink Developed on 6061 aluminum substrate 
|
| Geometry |
| Length / Width (mm) | from 15x15mm to 2500 x 1580mm | Thickness (mm) | 1.5-10mm optional; If dimension<= 300x300mm, thickness 3mm is recommended; If dimension >300x300m, thickness 4 mm is preferred; If dimension >500x500mm, thickness >=5mm is recommended |
| Dimension Tolerance (mm) | ±0.1mm | Thickness Tolerance (mm) | ±0.1mm |
| Edges | Sharp | Angle of the edges
| ±1° |
| Coating Description |
| Coating Type | Matte-finish&diffusive reflectance photosnesitive ink | Thickness of Coating Layer (um) | <=10um |
| Coating Surface | Matte and diffusive surface quality finish; therefore low reflectivity and no glare with on or off front lighting

Surface Flatness (um)
| overall size <=200mm | within 0.5mm |
| overall size 200-500mm | within 2mm |
| overall size 500-1000mm | within 3mm |
| overall size > 1000mm | >3mm |
| Prons and Cons |
| Disadvantage | If 1um feature position accuracy of the calbiration board/target is essential (System accuracy<=10um), photosensitive ink pattern developed on carbon fiber target is not an option; |
| Advantage | ● High Resolution | 

|
● Diffusive Reflectance & Matte-Finish Surface, no glare with front lighting on, no glare for outdoor applications as well;
|  |
| ● High Contrast Performance |


|
| ● Big Dimension Up To 2500x1580mm, suitable option to consider when you need a stable and rigid target for big FOV |  |
