Visible / RGB Collimated Laser Head
LZRGB-450-Collimated
450 nm blue, CW 5 - 5.5 W per emitter
450 nm blue collimated laser head for projection, display, industrial lighting and signalling. Blue is the colour that sets white balance in an RGB engine and the one that carries most of the optical power, which is why the sources here are rated at five watts and above, an order of magnitude above the red and green parts.
Estimated range
Range estimates apply to pulsed transmitter parts. This device is specified by its own parameters above.

| Operating mode | CW |
| Package | TO9 / LD bank (8 x LD + collimation) |
| Beam | Collimated; square or line spot after shaping |
| Operating case temperature | 0 to +70 |
| Qualified sources | 4 - Sharp, HiLaser, ams-OSRAM, Nichia |
| Spread across sources | Peak wavelength 430 - 463 nm across sources; threshold 0.24 - 0.37 A; operating current 2.9 - 3.3 A at the rated output. |
| Lifetime | MTTF > 2000 h at Tc = 50 °C and Iop = 2.3 A (GH04C05Y9G); 10000 h typical, 20000 h reference, at 50 % (HiLaserBTV100A). The ams-OSRAM and Nichia sheets in this summary carry no lifetime figure. |
Key features
- CW 5 W to 5.5 W per emitter at 450 nm; the Nichia part is rated per LD inside an 8-emitter bank
- Slope efficiency 1.45 - 2.0 W/A, the highest of the three colours, so a 3 A driver is enough for 5 W of light
- Threshold current 0.24 - 0.37 A; operating voltage 3.5 - 5.3 V
- Fast axis 35 - 57° before shaping - the widest of the three colours - narrowing to 0.65 - 1.05° when the bank is collimated
- Operating case temperature 0 to +70 °C, and storage to +85 °C
- The only one of the three colours the source sheets name for industrial lighting and signalling
