New Lead-Free 658nm Wavelength Laser Diodes from Photonic Products

Ideal for applications such as low level laser therapy, medical imaging, industrial alignment, laser levelling and barcode scanning, Sanyo’s new lead-free laser diodes, DL-6147-240 & DL-6147-040, produce 40mW CW output power at 658nm, which is 10mW more output power than the DL-5147-042 series laser diodes which they replaced in compliance with the RoHS Directive.

Supplied in a 5.6mm package, the Sanyo DL-6147-240 & DL-6147-040 laser diodes have a low threshold current of 30mA, typical operating current of 65mA, operating voltage of 2.4V, monitor output current of 0.35mA and differential efficiency of 1.1mW/mA. They have an operating temperature range of –10°C to +60°C.

The DL-6147-040 requires a negative (N type) power supply system, while the DL-6147-240 require a positive (P type) power supply system.

Virtually all Sanyo laser diodes are now lead-free.

Photonic Products, established in 1995, is both a manufacturer of innovative optoelectronic components based on semiconductor laser diode technology and also a specialist distributor of high performance industrial laser diodes, LEDs and high performance optical lenses.
