This laser diode emit high intensity visible light which can be hazardous to the human eye. Only for Professionals !

Known as "M-Type M140"

Manufacture: NICHIA Corporation Japan

Color output: Blue - 445nm

Continuous optical output power: 2W +/-0.15W

Operating current Typ.: 1.6A

Operating voltage Typ.: 4.6 - 4.8V

Efficiency min.: 1.2W/A

Beam Divergence θ II approx.: 15°

Beam Divergence θ⊥approx.: 40°

Small package TO-18: Ф5.6mm

Live Time aprox.: 20 000 h

Negative current transients greater than 25 µA or reverse voltages >4V, can destroy the LD.

This LD is needed very good cooling on in large current >1.4A.

Temperature on socket over 70 degree celsius is detrimental for the diode.

Without a cooling system: overheat and destroy to 3S after power on.

Rear side used for cooling, recommended 5mm thickness copper plate with triangle hole for pins.

This laser diode needs Driver - NOT included

For focusing requires 445nm three Layer coated glass focusing lens - NOT included

Test: Current = 1.8A -> Output power ~ 2.2W Efficiency ~26%

Attention: The following practices should be followed to minimize damage to static sensitive devices.
1. Discharge personal static before handling devices. Use grounding wrist strap.
2. After removed from anti static packing. Handle laser diode by the body.
3. Do not slide laser diode over any surface.
4. Only grounded tip soldering irons should be used.
5. Connect to ground Soldering Wire with Rosin Core.
6. Shorted both pins after finished.
7. Remove Short after connect to driver.
8. Use quality Constant Current Driver for this LD - accurate Current and Voltage.
9. Direct connect to Standard Power Supply will damage the LD.

Note:
If you do not follow these, this will damage the laser diode. For this reason Returns will not be accepted for this item.
