Optoelectronics Company reveals compact III-V laser diode modules
The miniature devices are composed of Oclaro's Opbext aluminium indium gallium phosphide (AlInGaP) and aluminium gallium arsenide (AlGaAs) laser diodes with externally adjustable optics. They also incorporate a Panasonic aspherical glass lens in a rugged modular anodised aluminium housing
The Optoelectronics Company, a manufacturer of innovative optoelectronic components and distributor of Oclaro (Opnext) laser diodes and Panasonic glass lenses, has launched another innovative and cost-effective range of laser diode modules.
The devices are optimised for compact integration into OEM applications where size is critical.
With a diameter of only 11 mm, the modules are ergonomically designed with a small form factor for integration into a wide range of applications. These include industrial and medical alignment, low level laser therapy, inspection and sensing where a tiny package is essential to fit into very compact spaces.
Tiny laser diode modules
This new range of laser diode modules combines a high performance Oclaro (Opnext) laser diode with externally adjustable optics, a Panasonic aspherical glass lens, sophisticated electronics and rugged modular anodised aluminium housing . It provides a reliable, energy-efficient and precise laser source for OEMs, end-users and systems integrators. A key feature is the brass lens holder which enables smoother, more accurate focussing by using a finer pitched thread.
“As applications get more sophisticated and devices get smaller, these laser modules are a perfect solution for OEMs to design in where space is at a premium”, comments Tony Pope, Managing Director, the Optoelectronics Company. “Combining high performance with energy efficiency, they require less power, generate less heat, have longer lifetimes and fit into smaller spaces than other laser sources” he adds.
The CW lasers produce a high-quality elliptical beam at 5 visible and infrared lasing wavelengths, (635 nm, 639 nm, 660 nm, 830 nm and 852 nm), and offer a combination of low noise and output stability with powers of up to 75 mW. For easy identification they can be supplied with coloured end caps or customer specified engraving on the rear sleeve. Mechanical dimensions are 11 mm diameter x 49 mm length.
The 635, 639 and 660 nm lasers are AlInGaP based while the 830 and 852 nm modules are based on AlGaAs.
With an operating voltage of 3 - 6V DC and a broad ambient temperature operating range from -10 degrees C to +500C, the modules are also static, surge and reverse-polarity protected and RoHS compliant. Electrical connections are made via 300 mm external flying leads.
Custom lasing wavelengths, from 405 nm to 852 nm, and power options are available on request. Both standard and custom configurations provide OEMs, end-users and systems integrators with complete cost-effective laser solutions.
The Optoelectronics Company, founded in 2009 by Tony Pope and Damon Cookman, is a manufacturer of high performance custom-designed and standard laser diode modules and also an authorised distributor of innovative optoelectronic components, including Oclaro (Opnext) Laser Diodes and Panasonic Lenses, to industrial, medical, telecommunications and defence markets in the UK, Europe and USA.
