Greetings, from what I have read the purpose of a collimated lens is to organize light waves into a parallel fashion. Do these lenses also focus light waves into a finite point smaller than the lens itself given varying distances from the diode? If so I am curious to hear anyone's experience with this lens: aixiz.com StoreFront. From what I understand other sites such as this one: Laser Diode Mounting Kits, Heatsink and Collimating Lens Holder - Optima provide information regarding the focused beam size given a specific diode in test. Unfortunately there is a $100 min order and the lenses are designed for 780 nm wavelengths. I am looking for a high quality lens for use with a 1 watt 808 nm diode that can create a focused beam less than or equal to 100 microns (.1 mm). Sorry for all the text, I would be very appreciative of any guidance.
