Default Help repairing 200mw 405nm bobslaser pen

I bought this used bobs laser 200mw 405nm pen here. it was broken when i purchased it. I have tested this module with my multimeter and the button is working and im getting power to diode everything checks out. Think i need new 405nm diode. what new diode can i fit in here? Anybody tinker with a bob laser pen before??... can i just slap any PHR in here and call it a day or something bigger??

Diode is getting power but not emitting anything? not even a dim light?

Yep. i thought it should at least give off a glow too. but nothing. i tried powering the diode directly to verify no light.

Also.... Can this lens be taken off the module without damage? i think i might see thread?? i need another needle nose to try and loosen
