Osram PL TB450 high power laser diode

The high power laser diode PL TB450 is mounted in a compact TO-56 package and features an optical power of 1.4 W, making it suitable for high quality, professional projectors, such as those used in offices, conference rooms and home cinemas.

The latest in the company’s portfolio of lasers on indium-gallium-nitride substrates, the diode also has a range of other applications from laser systems for stage and decoration illumination to medical applications.

Professional projectors with a luminous flux of more than 1000 lm are the main area of application. With a wavelength of 450 nm, it produces the exact blue laser light desired and, with 1.4 W (at room temperature and a current of 1.2 A), the high optical power required.

Efficiency of 27% (the ratio of light produced to electric power consumed) and the temperature of the laser will rise only slightly when in use, giving it a service life of up to 10,000 h at 40°C in continuous operation.
