Acrylic Lens
Acrylic Lens
A cheap lens made of transparent, high efficiency plastic (acrylic). The threads are also made of plastic, making this lens rather fragile.
Simply thread the new lens on being careful not to cross-thread the delicate plastic threads.
Replace lens quickly and do not keep laser diode exposed, as any internal dust may damage laser diode components.
Compatible only with lasers of <2W of optical power.
Includes the lens and its M9x0.5 threaded case as shown in the picture.
Will melt if front of pointer is held directly up to any surface.
Will melt if not cleaned regularly.
~80% efficient at collimating 450nm laser diode light.
Has minor light leaking (minor optical artifacts).
