A brighter, greener, more affordable laser light source

Light in the green spectrum appears brighter and is perceived more easily by the human eye than red light of the same optical output power and laser safety class. Consequently, distance meters, rangefinders and levellers; as used by builders, surveyors and other outdoor workers, can be used with more safety over greater distances with a green laser diode rather than a red. Other applications which benefit from higher visibility include military alignment and targeting, medical and industrial alignment and industrial instrumentation.

The new range of collimated laser diodes consists of an Osram 520nm direct green laser diode, a laser diode holder, a collimating lens holder and an aspherical collimating lens. The aspheric design of the lens enables a single lens to replace complex, multiple component optical systems and provide a high quality collimated beam. By adjusting the distance between the laser diode and the collimating lens, the factory-fixed beam can be set for a collimated or focused output to meet customer-specific requirements.

The Optoelectronics Company's collimated 520nm green laser diodes provide brightness, standard 30mW optical output power and an elliptical output beam with a collimated beam diameter of only 3.5x1mm. The collimators measure only 8mm in diameter and 9.6mm in length.

These 520nm laser diode collimators offer the simplest, easiest and most economical way to deliver the brightest laser light for a variety of OEM applications, particularly outdoor, daylight applications. Customised versions can be manufactured to order.
