HL40173MG, HL40175MG laser diodes offer increased voltage protection for biomedical, measurement, and 3D printing applications
Ushio has launched two new 405 nm, 600 mW (CW) laser diodes, HL40173MG and HL40175MG, with a lifetime* approximately twice that of conventional products.
Light source demand for mask-less (direct imaging) exposure systems, which expose high-definition circuit patterns on substrates, has grown significantly alongside consumer demand for smaller and higher performance smartphones.
There is also increasing demand for laser diodes in the 405 nm band, which are commonly used as light sources in biomedical, measurement, and 3D printing applications, which require further improvements in reliability and longer service life.
405 nm laser diode compatibility preserved while Zener diode adds improved versatility
In order to meet these market needs, Ushio has released HL40173MG and HL40175MG. The newly released 405 nm laser diodes maintain pin layout compatibility with the conventional products (HL40113MG and HL40115MG) while achieving approximately twice the lifetime of the conventional products.
In addition, HL40173MG and HL40175MG both feature a Zener diode as a safeguard against electrostatic discharge (ESD). The inclusion of the Zener means the 600 mW laser diodes gain a built-in resistance to ESD, over-voltage, and reverse voltage, thereby making the products easier for customers to handle.
Due to the marked improvements over previously released 405 nm, 600 mW laser diodes, Ushio actively encourages current 405 nm laser clients to consider switching to the HL40173MG and HL40175MG.
