To be launched in September, the device (part number ML562H84) eliminates the need for an external collimator lens and simplifies optical designs, reducing the size and BOM of projectors. The original built-in meniscus lens collimates the laser beam and reduces spread to about 1/700th, it collimates 98 percent or more of the laser beam to enable 2.5W output under pulse operation. Thanks to a large 9.0-mm-diameter transistor-outline can (TO-CAN) package with excellent heat dissipation, the laser operates in the temperature range of 0 to 45ºC at 2.5W pulse operation.
