Mitsubishi Electric to Launch High-Power 638-nm Red Laser Diode with Built-in Lens
2017/07/07

TOKYO, July 5, 2017 - Mitsubishi Electric Corporation (TOKYO: 6503) announced today a high-power 638 nanometer (nm) wavelength red laser diode (LD) offering an industry-leading 2.5W output under pulse operation with what is believed to be the industry’s first built-in meniscus lens, which will be launched on September 1. By eliminating the need for an external collimator lens, Mitsubishi Electric’s new red LD is expected to lead to simpler optical designs, reduced sizes and lower costs for projectors.

The light sources for projectors, conventionally mercury lamps, are being replaced with solid-state light sources that offer higher energy efficiency, a wider range of color expression and longer life. LDs deliver especially high output power, low power consumption due to efficient power-conversion, an unmatched color range due to narrow spectrum, and superior picture quality with high contrast ratio.
