    Unusual beam pattern

    I’m pretty new to lasers and was trying to find out if this is normal. I have a sanwu guardian 50mw 495nm and I know the dot is never really a perfect circle or anything but is it normal to have this giant square off to the side?

    Hello from MO

    Newcomer from STL here. I always thought lasers were a pretty cool hobby and last month I won a 50mw 495nm laser from sanwu lasers. Just came in today, just waiting for the batteries to charge. Anybody else have a laser like this? Nice to meet everyone!
