Ushio adding 400mW 404nm laser to violet range
In December, Ushio Inc of Tokyo, Japan will further expand its violet light product portfolio by starting production of a new 404nm laser diode.
Offering 400mW of continuous wave (CW) output power (with an absolute maximum rated output of 500mW) within Ushio’s standard MG (TO-56) 5.6mm-diameter CAN package and operating at temperatures of 0-30°C, the HL40093MG aims to meet demand for a violet laser diode (with emission wavelengths of 398-410nm) suitable for industrial applications and beyond.
Ushio says that its 404nm laser diode products are often used as light sources in direct imaging lithography systems, for exposing the high-definition circuit patterns on boards. Recently, demand for 404nm laser diodes from other non-industrial applications, such as evolving smartphones and high-definition 3D printers, has increased, notes the firm. This has driven it to launch a cost-effective laser diode to meet greater demand from both existing and emerging markets.
With beam divergence of 13° horizontal and 45° vertical, the HL40093MG shares optical and electrical characteristics, as well as pin layout, with the HL40053MG laser diode, providing another affordable option for existing HL40053MG users, as well as newcomers to 404nm lasers.
