Material

At minimum a table will exist for each material set to account zero (0). These tables are used in conjunction with the Material Configuration tables. Any specific accounts that need unique configuration will have their account number and material specific tables.

Low Minus Cntr

Enter default low minus power center thickness in mm

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 handle 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 is 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 common edged plano power lenses

Thickness for edge of a PLANO power lens. In Progressive or Executive styles, the ADD POWER is taken into consideration for thickness control.

Hi Plus Limit

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

Plus power at which the High Minus Cntr is reached.

Hi + Edge Thk

Enter edge thickness for common SF edged Hi Plus Limit power lenses

Minimum plus power thickness. Thickness is 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 plus powered GROOVE frame types. This setting overrides the thickness controls set above.

- String Edge

Enter edge thickness for minus power string lenses

Minimum edge thickness for minus powered GROOVE frame types. 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 is used unitl 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 pwr for indust. (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

Minimum thickness used when power exceeds diopter value specified under Ind + Thin Pwr.

Stock Thck Tol

Enter stock blank selection thickness tolerance

Deviation allowed for selection of a stock (pre-ground) lens during blank selection. The value entered here will allow a lens too think, or lens too thick, by this amount. In the case, of a groove or drill rimless frame type, the tolerance is only positive – allows a lens that is too thick only.

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 you 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 less than 1.5mm would not be selected automatically. You can still force a thickness in the lens blank window of the layout module to pull lenses of lesser thicknesses.

Edg SV Psm Rd

Enter Y to default edged SV lenses doing prism reduction

If the entry is (Y) the system will grind the minimum amount of oprism for cut out on EDGED work only. Blank size selection is not altered.
