The new Laserline OTX optics are designed for industrial heat treatment and for use in combination with Laserline’s diode lasers. The optics with a large homogenized spot enable the processing of large areas. Beam widths of over 1.5 meters can be realized. The ultra-wide beam technology is being used successfully in the electrode drying of lithium-ion batteries in a roll-to-roll process for example. OTX is the newest member of the established OTS optic series and enables WPE of 52% combined in Laserline drying systems.
