A QVS video system calibration may include:
- Parfocalization for auto focus
- Parcentricity of zoom lens
- FOV edge detection accuracy
- X/Y axis squareness of stage travel
- X/Y axis linear or nonlinear grid (up to 25 intersections)
- Z axis squareness to X/Y travel
- Z axis linear calibration
A QVS optical comparator calibration may include:
- Table squareness to optical axis
- Focus squareness to optical axis
- Micrometer accuracy, if equipped
- Perpendicularity of X to Y axis
- Edge detection accuracy to centerline (OGP machines)
- Magnification and distortion accuracy for all lenses equipped with machine
- Chart angular rotation in 90° increments
- Chart centerline in 180° increments
- X and Y axis lead accuracy – every inch for the length of travel
