HERTFORDSHIRE, UK, May 9, 2006 -- Photonic Products, a manufacturer of electro-optical subassemblies and optoelectronic components and a high-performance industrial laser diode distributor, announced the launch of a new high-visibility, short wavelength laser diode from Sanyo, rated to 50 °C, which offers a very high optical output power of 40 mW continuous wave with a low threshold current of 60 mA in a 9 mm package.

The improved beam circularity results in greater efficiency and consequently significant cost savings for OEMs and, combined with the high optical output power and high visibility, makes it an ideal laser diode for use as a light source in laser displays, laser levellers and line-markers, bar-code scanners, machine vision and medical and dental imaging applications, Photonics Products said.

Supplied in a 9 mm package, the Sanyo DL-LS1158 laser diode has a high output power of 40 mW continuous wave at a visible wavelength of 638 nm, a low threshold current of 60 mA, low operating voltage of 2.4 V, typical operating current of 100 mA, a differential efficiency of 1.0 mW/mA, monitoring output current of 0.4 mA and an operating temperature range of -10 to +50 °C. It requires a negative (N type) power supply system.

The Sanyo DL-LS1158 laser diode is PB-free in compliance with the RoHS Directive (restrictions on the use of certain hazardous substances in electrical and electronic equipment). For more information, visit:; e-mail:
