Keyence Corp. of America: Laser marking
Keyence’s MD-V9900 series YVO4 laser marker provides 3-axis motion for a wide variety of marking.
The 3- axis motion of the MD-V can mark on deformed or curved surfaces, inclines, cylinders or circular cones at speeds up to 12,000mm/s without compromising character clarity. With the MD-V’s variable focal length, maximum spot position can be set at any focal length within a 42mm range. This range of focal length significantly reduces installation time and cost by eliminating the need for a mechanical stage that adjusts during product changeovers, or when it is necessary to mark products of varying heights. The 300 x 300-mm wide marking area of the MD-V is largest in its class. The MD-V series utilizes a special lens system along with its unique 3-axis control to create this highly accurate 300 x 300-mm wide marking area, eliminating the need for mechanical adjustment while maintaining character integrity. The series comes equipped with the newly developed Dual End Pumping Cavity (DEPC). This new technology improves the optical exchange efficiency to double that of conventional markers. The higher efficiency means that the diode has to use less current to generate equivalent power, thus reducing energy consumption while increasing the diode’s life.
