Material

At a minimum, a table

exists for each material set to account zero (0). These tables

get used in conjunction with the Material Configuration tables. Any specific accounts that need unique configuration

can have their account number and material-specific tables.

Low Minus Cntr

Enter default low minus power center thickness in mm

The thickness for minus powered lenses up to Low Minus Lmt. The thickness remains constant until power exceeds the limit. Progressive and Executive lenses include the ADD POWER when determining the value of thickness.

Low Minus Lmt

Enter default low minus power limit (for low minus center thickness)

Upper power range (most minus) that is controlled by the Low Minus Cntr value. The High Minus Cntr and High Minus Lmt controls

to manage the powers exceeding this range limit.

High Minus Cntr

Enter default high minus power center thickness in mm

Minimum thickness to allow for minus powers. Once a lens exceeds the Low Minus Lmt, the thickness

gets gradually reduced to this thickness by the time the power reaches the High Minus Lmt value.

High Minus Lmt

Enter default high minus power limit (for high minus center thickness)

Minus power at which the High Minus Cntr is reached.

Plano Edge Thk

Enter default edge thickness for

standard edged

Plano power lenses

The thickness for the edge of a PLANO power lens. In Progressive or Executive styles, the ADD POWER

gets taken into consideration for thickness control.

Hi Plus Limit

Enter default high plus power limit (for high plus edge thickness)

The plus power at which the High Minus Cntr is reached.

Hi + Edge Thk

Enter edge thickness for

standard SF edged Hi Plus Limit power lenses

Minimum plus power thickness. Thickness

gets gradually reduced from the value set for Plano Edge Thk to this thickness.

Fct&Str Edge

Enter edge thickness for facet and string (comb.) plus/minus power lenses

Minimum edge thickness for a GROOVE frame type with a FACET applied. Thickness overrides default edge controls.

Drill Point Min

Enter drill point minimum thickness

+5.00 Facet Edge

Enter edge thickness for facet lenses at +5.00 or stronger

Minimum edge thickness for a plus powered lens when a FACET is applied, and the power exceeds +5.00 diopters.

Plano Facet Edge

Enter edge thickness for facet lenses at

Plano or minus power

Minimum edge thickness for a PLANO powered, FACET applied

edge type.

+ String Edge

Enter edge thickness for plus power string lenses

Minimum edge thickness for a plus powered GROOVE frame

type. This setting overrides the thickness controls set above.

- String Edge

Enter edge thickness for minus power string lenses

Minimum edge thickness for a minus powered GROOVE frame

type. This setting overrides the thickness controls for minus powers.

Note: Will increase the center thickness of weak powered (minus) lenses

if the default setting would make the edge too thin.

Indust. Thick

Enter default minus and

Plano lens thickness for industrial (safety) lenses

Minimum thickness for SAFETY work. This thickness

gets used

until the power exceeds Ind + Thin Pwr, at which time it switches over to the thickness under Ind + 1.00 Thk.

Ind + Thin Pwr

Enter default starting plus lens thinning

power for

industrial (safety) lenses

Minimum Power to switch over to Ind +1.00 Thk thickness control.

Ind +10.0 Thk

Enter default thickness for industrial (safety) lenses at +10.00 power

The minimum thickness used when power exceeds the diopter value specified under Ind + Thin Pwr.

Stock Thck Tol

Enter the stock

Blank Selection thickness tolerance amount.

Deviation allowed for the selection of a stock (pre-ground) lens during

Blank Selection. The value entered here

allows a lens that is too

thin, or lens too thick, by this amount. In the case

of a groove or drill rimless frame type, the tolerance is only positive – it allows a lens that is too thick only.

You are setting up Stock thickness tolerance limits. This setting is usually the same as our stock removal, but you can edit this value to force Optifacts to pull a 1.5mm thick stock lens where you normally would only grind to a 1.8 mm center. Example: If your system will normally only grind to a 1.8 mm center thickness, but you would like the system to be able to pull a 1.5mm finished lens, if available, set

your stock thickness tolerance to at least 0.3 mm. (1.8 - 1.5 = 0.3). In this example, any finished stock lenses that have a thickness of less than 1.5mm would not

get selected automatically. You can still force a thickness in the lens blank window of the layout module to pull lenses of lesser thicknesses.
