Re: First build; PHR-803T Laser
The lens has two notches on the top of it. Theyre the two small straight indents directly across from each other on the black part of the lens.
Well Blu-rays need the lens close to them the focus to infinity. Which is why pressing the diode in the module past being just "flush" is necessary when using an acrylic lens. Glass lenses get closer to the diode and give you a wider range of focus.
So either disassemble the module and press the diode in further, or invest in a glass lens. Or you could flip the acrylic lens upside down, but iirc, that causes the dot to have a weird pattern around it
