DIY Laser Pointer Safety Test [Safety]

Whether you’re a typical presentation giver or you only wish to pop balloons and start fires, laser pointers are getting way more common, albeit unsafe, household objects. Here’s tips on how to build a small rig to discover your laser pointer’s safety.

A recent study by the National Institute of Standards and Technology found that some cheap laser pointers are especially notorious for emitting too much infrared light, meaning they’re rather more prone to cause vision problems in the event you aren’t extra careful. Luckily, when you’ve got a digicam, a webcam, a CD, and some paper cups, you might test to work out if yours is without doubt one of the worse offenders.

Apart from being an excellent safety test, it’s actually a fab little project-since webcams often are frequently more sensitive to infrared light, you may compare a right away photo of the laser beam from a webcam and an identical picture from an ordinary camera to look in the event that your laser pointer has a stronger infrared output than it will.
