Economical Green Line Laser Module 520 nm, Class 1, 7~10 VDC, >60° Fan Angle, 0.3~1.8m Working Distance, VLM-520-28 LPT - Industrial Alignment Laser for Automation & Machine Vision

The item arrived in time but it's completely damaged.

装置への材料供給の際の位置決めラインとして使用しましたが、明るくて見やすいです。

This thing is tiny. I’m talking smol compared to other lasers I’ve purchased. Bought this specifically for the higher voltage range forgetting that my power supply changed to 5.5vdc. Still works but seems to pick up full brightness at about 6.5v right under its rated 7v minimum and stays consistent to the top end of voltage range. Idk what you would use this for but seems like better quality than most so far. I’m just going to mount it to the hood of my RC car so I can make trajectory adjustments better doing speed runs at night lol. Plenty bright for my needs. Haven’t tested in daylight yet but green usually picks up better and this wasn’t sold as a daytime laser.

ラインレーザーで、動作電圧が7~10v DC APC 内臓で単3乾電池、直列6個で使用可能。電源配線がリード線(赤+ 黒－)だけなので、部品として組み込みが簡単。就寝前に頻繁に片手指で主電源SW 操作の他に、レーザー射出黄SW (押し下げ時のみON、中央OFF ,上げON固定) のON- OFF するので、コンパクトにする必要があり、サイズでも部品選定しました。実際は暗い部屋で、対象物の見える化確認に使用します。照射範囲が60°外れるとライン品質はドット状になる。暗いところでは、コリメーターレンズの性能品質が分かり易い。 ※ LED×２ 1KΩ抵抗×２ 使用。 電圧降下での電池新品時の動作電圧範囲を確保と電圧モニター。 ※添付写真は電圧DC9V時

There’s not a whole lot to say other than it works as described in the description and specifications. My application doesn’t require visibility in full sunlight but it’s nice and bright indoors and a huge step up from a red laser of comparable power. I took a chance on this because it had a 3.2 rating when I purchased it. From my experience, it should be at least a 4.5. I’m ordering another and will change my rating/review if needed.

We were working on a fun project- building a "laser swamp" (look it up on youtube!) The full kits are sold for the tune of $400 a piece, so this laser is a great money-saver! (I highly recommend to purchase laser brackets for them as well, it will make leveling A LOT easier!) All lasers worked, but there was a visible brightness variance from unit to unit. It would also be a lot better if the spread angle were 90°, not 60°. Anyhow, they worked well in the project, the swamp was amazing!
