Photonic Products are pleased to offer lead-free laser diodes, rated to 50°C, offering very high output powers of 40 mW absolute maximum (DL-LS1148) or 25 mW absolute maximum (DL-LS1164), in a tiny 5.6 mm package. These very high output powers were previously available only in a 9mm package laser diode.

The Sanyo DL-LS1148 and DL-LS1164 638nm laser diodes are part of a range of laser diodes developed by Sanyo with a new diode type structure which results in a beam circularity ratio of 2:1, compared to the previous beam circularity ratio of 4:1.

The smallness of these laser diodes combined with their improved beam circularity results makes them ideal for products such as laser levellers and line-markers, bar-code scanners, machine vision and alignment and medical and dental imaging applications.

Supplied in a 5.6 mm package, the Sanyo DL-LS1148 and DL-LS1164 laser diodes have a low threshold current of 65mA, low operating voltage of 2.4 V, differential efficiency of 0.95mW/mA and an operating temperature range of –10°C to +5°C.

The Sanyo DL-LS1148 has a high output power of 40 mW CW at a visible wavelength of 638 nm, typical operating current of 110 mA, monitor output current of 0.6mA and requires a negative (N type) power supply system.

The Sanyo DL-LS1164 has a high output power of 25mW CW at a visible wavelength of 638 nm, typical operating current of 80 mA, monitor output current of 0.3mA and requires a negative (N type) power supply system.

These Sanyo laser diodes are now lead-free in compliance with the RoHS Directive.
