Check the listing for details. 808nm 3W High Power B-Mount Laser Diode. Condition: New. Listed at 70.00 USD. Normal 0 false false false EN-US ZH-CN X-NONE 808nm 3W High-Power B-Mount Laser Diode Description: This is an 808nm laser diode, which can output 3W optical power from its 200μm aperture. It 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 5 such lasers in stock. The lasers are brand new not used. Specifications: Characteristics Specification 808nm 3W B-Mount Laser Diode CW output power (W) 3.0 Peak wavelength (nm) 808±3 Spectral width (nm) ≤4 Threshold current (A) ≤0.9 Operating current (A) ≤3.4 Slope efficiency (W/A) ≥1.1 Beam divergence θ∥×θ⊥ (deg.) 8/30 Wavelength temperature coefficient (nm/℃) 0.3 Emitting area (μm) 200×1 Lifetime(hour) >10,000 Package B-Mount Data Sheet Available for each diode 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 3.4 amps in this case).
