I got asked a series of questions by reader “me_wwwing” after the article Laser with LCOS is Focus Free — Yes Really! that I am answering in this post because I thought they would be of general interest. I did have…

In my last post on Direct Green Lasers (DGL) I wrote about electrical power to lumens conversion. In this post, I am going to talk about the color range/space and how it is affected by the green wavelength used. …
In my last blog I wrote about the power measurements on the ShowWX and a number of people asking “where did the all the ShowWX’s power go?” Microvision wants you to think that they just point the lasers directly at…
