Description

Pack of 10 pcs 811nm 3W High-Power B-Mount Laser Diode
Description:
This is a pack of 10 pcs 811nm laser diode which can output 3W optical power from its 200μm aperture. Each diode was bonded on B-Mount, which was made in the USA. It came to us with a lot of other electronic/opto-electronic related surplus. We have more than 20 such lasers in stock. The lasers are brand new not used.

By Bidding, you must agree and accept:
·
You are over 18 years old and understand the dangers and risks of laser use, and will use this component responsibly.
·
You will use this component in a legal, safe manner to ensure audience and personnel safety.
·
You have a working knowledge of laser diodes. You understand ESD, and the static sensitivity of this component.
·
Laser beam is harmful for eyes during process. Please avoid any directly see on the aperture. Never shine laser beam on human or animals.
·
You accept these diodes as electronic components for integrating them into a system designed by yourself. You relieve the SELLER, and E-bay from any and all LIABILITY from damage or injury that may arise from use of this laser.
If you are not serious, please do not place a bid.
Return policy:
·
We will test the lasers before shipment; buyer should contact us as soon as he find it is defective;
·
Refund request should be made within 14 days buyer receives the product;
·
Replacement request should be made within 30 days buyer receives the product;
·
Since this is a Do-It-Yourself laser diode, we only refund if the product arrive to be defective; so please use it gently and properly when you assemble your device; you also need to send back in original shape to get refund/replacement; we won't refund or replace if the laser was damaged by buyers;
Some tips for operating laser diode:
·
Please use a power supply with stable output. Transient current spikes should be avoided.
·
Please always connect the pins correctly.
·
Heat sink with good thermal dissipation is required for holding the laser otherwise the laser will be burned.
·
Please use eye protection when you operate the laser.
·
It is better to wear an antistatic wrist band.
·
You should always start with current well below the diodes maximum (about 3.6 amps in this case).
