value of laser at the time of adjustment after the latest all-initialization, 25mA in this example.The last two numbers ("30" in
"2530") shows the present current value of laser, 30mA in this example.The first two numbers ("25" in "2530") usually shows
current value of laser at the time of shipment, so you can see how the product has been deteriorated by comparing the first two
numbers ("25" in "2530") and the last two numbers ("30" in "2530").
