What is a Metrologic Neon Laser?

Question

And what kind of value does it have?

Answer 1

First off, it is a helium-neon laser, not a neon laser.  There are lots of old Metrologic He-Ne laser models, googling:

"metrologic he-ne laser"

turns up a lot of information.  If you enter the model number you will find lots of details for your laser.
