DTR-G-8 Broadband Glass Laser Collimation Lens - WHY COMPROMISE..HAVE IT ALL!!!

Description: FINALLY NO MORE COMPROMISING LARGE POWER LOSSES FOR A REDUCED SPOT SIZE OR EXCESSIVE STRAY LIGHT PROJECTING AROUND THE SPOT!!! DTR-G-8 Glass Collimation Lens.Broadband AR Coating 400nm-700nm It's being called the "miracle lens". This lens is a long focal length single element glass lens with a broadband AR coating. It has a 90% pas efficiency which is amazing for a longer focal length lens. It does an amazing job of cleaning up stray light around the projected spot with many common diodes caused by the small amounts of uncollmated light escaping the lasing cavity reflecting off things like the edge of the emitter, walls of the module or inner walls of the lens barrel. causes things like the ghost box image that is projected under the spot generated from the newer very high power diodes when using a short focal length single element lens like the DTR-G-2 or countless other similar lenses being sold as G-2's. It creates a greatly reduced spot size while maintaining a 90% pass efficiency compared to the 96% pass efficiency of a DTR-G-2.I will add more specs, testing data, comparisons with various common diode/lens combinations and pictures of spot with various diodes to come as soon as I get to them. In the mean time see the threads over on the forum linked above for lots of community testing, comparisons with other common lenses, other observations, questions and general discussion. Check out the this link to the original thread on over on LPF forum.New DTR-G-8 lens Specifications(PGM)Precision Glass Molding Glass Type: Single Element Aspheric (EFL：8mm) (NA：0.20) Housing：M9X0.5mm AR Coating：Broadband(400nm-700nm) Some examples of spot shape using a 1W 520nm Diode and several common lenses.
