FAQ: “A D25LT customer recently chose a A02-1002-965 Light Trap with their order. For what reason or applications should one choose this part?”
The D25LT typically comes standard with a D02-1013-408 Black Glass (100 mm x 100 mm; 4 in x 4 in) affixed to a metal backing plate, to set bottom-of-scale during the standardization protocol.However, in some factories, particularly food plants, there is a customer concern about possible glass breakage even with the metal backing.
For customer situations where black glass cannot be used, HunterLab offers the A02-1002-965 Light Trap as equivalent in performance to the black glass for standardizing the instrument to 0% reflectance.
FAQ: “Why not just have the Light Trap as the only bottom-of-scale standard instead of both of them?”
The black glass is the traditional bottom-of-scale instrument standard for directional geometry instruments such as the D25LT. It is also less expensive to manufacture than the light trap. HunterLab offers this light trap to address a specific customer concern with the D25LT Port Up sensor and have done so with previous sensors such as the D25L and Vista 45/0 LAV.
