REFLEX: TECHNOLOGY TO MEET STYLE Introduction to 4 & 5 mm prisms 2001-01-0460

4 & 5mm reflex prisms are newborn options in automotive lighting design. They are very useful for new styling configurations, especially when mixed with optics.
But 4 & 5mm reflex patterns can create defaults directly linked to these prisms' size. These defaults can be sink marks or surface distortions. They affect the photometrical output and the overall aspect of molded lenses.
Thus the 4 & 5mm reflex prisms' use requires an increased precision regarding the effective optical angles in order to obtain a photometrical quality comparable to the one with conventional size of prisms (2.38mm).
