| Custom High resoluiton printing on ceramic test&calibration target: For front light illumination, reflective illumination, natural illumination applications | |||
| Accuracy (um) | +/- 10um | Smallest line width/ Minimumfeature size (mm) | 0.3mm |
| Thickness of pattern coating (um) | 20um | Thickness (mm) | 1.0-2.0mm optional |
| Maximum dimension (mm) | 200 x200mm | Tolerance of outer dimension (mm) | +/-0.1 mm |
| Manfuacturing process | High resolution printing | 3rd party certification | On request |
| Coating of pattern | Matte and diffusive reflectance ink | Matte and diffusive reflectance surface of ceramic material | White or near white reflective material comprising of 96% compacted Alumina. Ceramics are commonly noted for their matte surface quality finish; therefore low reflectivity while retaining a white reflective surface as well as resistance to breakage |
| Disadvantage | If +/-1um accuracy is essential, high resolution printing is not an option | Advantage | ¡ñ If +/-10 accuracy is satisfying, high resolution printing is a compromise choice in accuracy and cost aspects ; ¡ñ Matte and diffuse reflectance surface, no glare with on or off front lighting |
| Chemically and dimensionally stable, and reasonably hard | |||
| If you don't have pattern design, Dot Vision engineer could help you design the pattern/drawing | |||
| Holes/ angles/ corners on the calibration target are on request |  | ||
| Irregular shapes are on request |  | ||
| Mechanical Protection/Mounting frame are on requrest |  | ||
| Properties of ceramic | |||
| Alumina content | 96% | Thermal Expansion Coeff (25 to 800 ¡æ) | 7.2X10-6 / ¡æ |
| Specific Gravity | ¡Ý 3.6 g/cm3 | Rockwell hardness | ¡Ý80 HRA |
| Warping degree | ¡Ü 2% | Surface roughness (um) | Ra= 0.2-0.7um |
Perpendicularity | 0.15mm MAX | Squareness | 0.15mm MAX |
| Bending Strength | > 350MPa | Dielectric constant | 9-10 MHz |
With guaranteed product quality, all calibration targets are tested using precision measurement instruments before packing and delivery to clients to ensure the accuracy.
