There is a choice of different optical elements, to meet the systems requirement on point. Three different Powell-Lenses are available, producing a a straight line with homogenous intensity. This enables many different applications with the same laser type. The ELP lens offers an extended depth of focus where the height of objects vary a lot. The standard Powell lens SLP is suitable for most applications. For very fine lines, the FLP lens offers the highest accuracy to the cost of focus depth.
