Laser

Dark matter is thought to outnumber regular matter by a factor of five to one – so why can’t we find the stuff? A new study proposes looking for it from space, using a satellite containing a levitating piece of graphite and a laser.

Claiming the title of the world's number one 4K UHD and DLP brand, Optoma has introduced a capable new laser projector. The UHZ68LV puts out 5,000 lumens for daytime viewing, and has a maximum thrown image size of 300 inches.

There are wireless computer mice, touchpads, TV remotes, and laser pointers … and then there's the Xring D13. It combines all of those tools in one wireless device, which could be yours for US$109.

After raising more than $10 million in crowdfunded cash last year, Valerion has announced the official consumer launch of its VisionMaster Pro 2 triple-laser long-throw smart projector – with Google TV loaded in for streaming entertainment.

A frothy breakthrough at Lawrence Livermore National Laboratory (LLNL), using lasers with a silver metal foam that's as light as air, has created the brightest yet X-ray source ever, twice as brilliant as that of anything previous.

Valerion launched a bunch of 4K projectors on Kickstarter last November, and went on to raise more than $10 million. Now the startup has officially released its VisionMaster Max at CES 2025, while also debuting its new interchangeable lens.

It can be hard, keeping a spray paint can at that Goldilocks not-too-close/not-too-far distance from the surface being painted. The Laser Focus Sprayer is made to take the guesswork out of doing so, by putting a dual-laser sighting system on any can.

Panasonic has bumped up the brightness for a new series of short-throw projectors. Billed as the company's most powerful fixed, short-throw LCD laser projectors to date, one model puts out 7,000 lumens and the other manages 6,200 lumens.

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. If you manipulate a laser just right, then hit it side-on with another light source, it’s possible to create this bizarre optical effect.

University of Mississippi researchers have devised a faster method for detecting landmines – millions of which pose a lethal threat to people in war-ravaged countries. This breakthrough could help save thousands of lives a year.

Sharp Imaging has added a new family member to its pro-level X Series projectors. The dual-laser XP-X171Q should provide, ahem, sharp 4K visuals even in brightly lit rooms.

Following a number of industry partnerships, Leica announced its own smart projector in 2022. Now that UST Laser TV is joined by a compact audiovisual treat designed for "maximum flexibility and cinema feeling in Leica premium image quality."
