FAC collimated lens is an aspheric cylindrical lens designed for collimating the bar-type laser incident and to avoid light divergence. Because of the aspheric form of the lens, it offers a low spherical aberration.

◦Because of its short back focus feature, it can be used with the light emitting section attach to the lens to perform the best focusing effects.
◦Can also be used as a light capturing lens for line CCD sensor or as a laser line generator.
◦Both sides have AR coating which limits the lost in illumination and have high focusing efficiency.

▶The pricing varies depending on the quantity of the order, please contact our International Sales Division.
▶We accept low quantity order.

Attention

▶The perfect collimated light can be obtained only with the type of high power Laser Diode Array light (TEM).
▶The back-focus (bf) is extremely short, the CAN type LD or LD with cover glass may face bad focusing problem.
▶There is no focus effect on the long side of the lens; therefore, divergence problem may remain.
▶The imaging points of the emitted light from the cylindrical lens are different from the vertical and the horizontal side.
