Integrated, dual-wavelength red and infrared laser diodes for scanning & counting
Distributor RS Components has a pair of new single-chip dual-wavelength red/infrared laser diodes that offer high output characteristics in a compact size. Manufactured by Panasonic, these devices are suited for use in barcode readers and a multitude of sensing-based applications such as laser distance sensors for industrial use, or flow cytometers in biomedical applications.
The single-chip solution eliminates the need for multiple components, with both red and infrared lasers on board a small flat three-pin package. Offering stable power output even under high temperatures, these new dual wavelength laser diodes are roughly 20 to 30% more efficient than conventional laser diodes. They also exhibit exceptional accuracy in laser beam spacing, leading to greater design-in flexibility.
The LNCT22PK01WW and LNCT28PF01WW are MOCVD (Metal-Organic Chemical Vapour Deposition) fabricated 660 nm and 780 nm band dual-wavelength devices that feature a multi-quantum-well structure that has been adapted to fit an open frame type package to reduce size and weight.
Key specifications are: dual wavelengths of 661/661 nm (typical) and 785/783 nm (typical); output power of 280/300 mW (pulse) for red and 380/380 mW (pulse) for infrared; and an operating temperature range of –10 to +85°C for both devices.
