5.6mm Laser Diode Module w/ 12mm IDG2 lens for 405-450nm wavelengths, will work for other wavelength as well.This lens is a high output lens, and with all multimode diodes it will have a shadow around the dot. This is normal output from these lens, so do not worry if you have it. This lens is best choice for close range cutting with lasers. Brass holder, brass module.
Wavelengths we have tested these with:405nm445nm450nm465nm473nm520nm^ All had about the same result, more output power; with much higher divergence. They cannot be beat for up-close burning or engraving; but for long-distance beam viewing these are not the perfect lens. Visit my store to buy a 3-Element lens for this purpose.
405-G-2 405nm/450nm/462nm/515nm/520nm lens
The transparence ratio of the normal collimation lens of the market is around 70-80% due to the long focus distance.The original laser diode\'s light is difused a long focus lens will bring more power lost.The normal collimation lens\'s focus is 7-8mm but this lens\' focus is around 2.357mm.So,the power lost will be the lessand the beam effect is the best!
