GLOSSARY OF TERMS

Batch Blocking: Method of entering jobs. For example, with a stack of ten or more trays, you can enter or scan all jobs in succession and then start to process them either by first in/ first out or last in/ first out.

Blocking Chamber: Where the lens is placed for analysis and blocking. Four grippers will center and hold the lens in place until the blocking is complete.

Coordinate Origin: Position 0,0 for X and Y; it is the starting point for the placement of the finished block on the lens.

Edge Detection Threshold: Refers to the sensitivity of the camera image to detect the edge of a lens for diameter measurement. This is found on the Technician screen and is generally numbered between 15 and 20.

Grippers: Four paddles that clamp and center the lens in the blocking chamber once Start is selected.

Gain: Intensity of the brightness of the camera.

Glass Plate: Found in the accessory kit during shipping; it covers the opening in the blocking chamber.

LCD: Stands for Liquid Crystal Display. It is found under the glass plate in the blocking chamber.

Measured: On the Analysis screen (on the right side of the screen), the measured results of the lens being analyzed and compared to the Tolerances screen for accuracy (generally ANSI).

Oval Calibration Template: This is a pattern attached to a Vario block found in the accessory kit. It is used to calibrate the block position and axis of the chuck.

Power Checks: The number of times the camera will take a shot and be analyzed.

Power Offset: In the Calibration screen; used if a consistent power error occurs. For example, all minus lenses are coming out .25 diopters weak so you would put a +.25 adjustment in this field.

Power Targets: The number of different sized targets that will be used in the analysis.

Prescribed: The prescription as written by the optician – sent from the retail location to the lab.

Red Circle Superimposed on the Lens on the Analysis Screen: This is the position of the block on the lens and is the geometric center of the frame shape.
