It is the most challenge work for users to make super accurate cross line measurement at quite long work distances. While after I am trying to make cross measuring with high brightness 635nm cross Green 1mW Laser Pointer pen alignment, it is always able to generates high brightness vertical and horizontal lines clearly and accurately on all desi working surfaces. Available with wide output power level of 5mW to 100mW, this pro cross laser can easily bring users precise cross line measurement efficiently.
Comparing with formal available dot or line projecting 50mw Green Laser Pointer , the design of cross line laser is a bit complex, but it is always bringing users the biggest convenience in a lot of high tech machinery processing works. If users are still using triangular meter or blocking board, it is impossible for users to make cross line measurement at quite long distance or quite hard reaching surfaces. Although you can also using mechanical cross measuring tools, while there are places where human hands cannot achieve.
From the very beginning design, 635nm cross laser alignment adopts the most compact and portable pen design. Besides easy carry and operation, for the most important of all, owing to its quite compact pen design with diameter of 16mm and 26mm, this crosshair Red laser pointer 5mW 3in1 module is always allowing very easy installation on any requi machine or devices. Its operation has no limitation of surrounding working environments. According to electric lines connected with 635nm laser module and DC power supply, with wide range of 0.5 meter to 3 meters, users can make the easiest installation of this cross laser alignment freely.
A low-cost home Air rifle laser sight projector, heavily advertised and widely available in stores, is raising concerns about pilot safety — especially because many have been purchased for outdoor Christmas decorating.
Between November 18 and December 6 2015, there have been at least three incidents, involving six aircraft, where pilots were illuminated with light from “Star Shower” laser projectors. In all cases, the illumination appea to be inadvertent. The devices were being used for holiday decorating, and stray beams went into airspace. (E.g., a person was not knowingly aiming the Star Shower at an aircraft, or the flight path of an aircraft.)
The Star Shower emits “thousands” of laser beams from two sources, one green and one . A homeowner can simply aim the Star Shower at her house or foliage, and instantly cover it with green, or green plus , laser dots.
