Product and Technology Ushio to release new 400mW (CW) 404nm laser diode in December
2020.11.10
Beginning in December, Ushio, Inc. will further expand its violet product portfolio with the manufacture of a new 404nm laser diode (LD). Offering 400mW (max. rated 500mW) of CW output power within a Φ5.6mm CAN package, HL40093MG will meet the demand for a violet wavelength LD suitable for use in industrial applications and beyond.
Ushio’s violet LD products have often been used as light sources within direct imaging lithography systems, with the purpose of exposing the high-definition circuit patterns on boards. Recently, demand for violet LDs from other non-industrial applications (such as evolving smartphones and high-definition 3D printers) has increased, which has driven Ushio to release a cost-effective LD that will meet increased demand from both existing and emerging markets.
HL40093MG shares optical and electrical characteristics, as well as PIN layout, with current Ushio product HL40053MG, making it an affordable option for current HL40053MG users and others.
