Sanwa Laser Power Meters
There are two types of laser power meter offered by Sanwa-one is the analog type while the other one is the digital. Laser power meters are measuring instruments that let a laser beam emitted from a laser light source enter the sensor light receiver and indicate the value by converting light energy into electrical signals. The laser power meter is used for testing the light power and maintaining laser operating equipment. I personally don’t own these meters because my daily job is not dealing with any optical/laser equipment. However if you are in the line of repairing equipment that uses the silicon photodiode or anything that deals with laser, i guess you should get one of these Sanwa laser power metes.
