## Overview

The VLM-520-27 LPA Green Line Laser Module is a high-precision industrial laser tool featuring a direct green diode laser at 520nm wavelength. It delivers an ultra-thin 3.5mm line at 10 meters with ±1mm accuracy at 5 meters, housed in a durable solid brass body for shock resistance and heat management. Designed for demanding environments, it operates across a wide temperature range and offers over 10,000 hours of reliable continuous use, making it ideal for professional applications in metal, wood, textile, automotive, and medical industries.

## Description

APPLICATIONS: Straight Green Line from Direct Green Laser Diode.  Wood processing.  Metal processing.  Stone processing.  Textile industry.  Food industry.  Automotive industry.  Medical science.   Why choose direct green laser module?  Direct Green Lasers are direct-diode semiconductor lasers. The stability of the laser output is greatly improved.  Most green laser modules on the market are DPSS (diode pumped solid state) laser modules. DPSS (Diode-Pumped Solid State) is a conventional laser module that emits an infrared laser diode with a wavelength of 808nm and turns it into green by the crystal. This is actually a very inefficient way of producing a laser beam as there is significant power loss.  For Direct Green Laser Module, the semiconductor laser itself emits directly. The stability of the laser output is greatly improved since there is no additional crystal. Thanks to their good efficiency, the temperature increase of the lasers during operation is minimized. A long lifetime and high reliability at continuous operation is guaranteed.Mean time to failure (MTTF) 77°F: 10,000 hours. Integrated industrial use direct green laser diode has 10,000 hours average working life.

## Features

- Designed and manufactured in Taiwan, ensuring high quality and long-lasting performance. Industrial-use Line Laser. Direct Green Laser Diode for large temperature operation range. Line-width at the distance of 10 meters(32.81ft.) is less than 3.5mm(0.1378 in.). Laser line accuracy: 40" (+/- 1mm @5m). Operating Voltage: 7~10 VDC. Dimensions: D0.492 x 1.181 inches (D12.5 x 30 mm).
- Wave length: 520nm. Laser power output: Class I. (Update 02/26/2024 - The laser output (the brightness) is exactly the same as before. The reason why the Laser Class is changed because according to the latest IEC 60825-1 regulations. Therefore, you see that its Class is changed from "Class II" to "Class I" now, even though the brightness is exactly the same as before.)
- The best line-accuracy and the widest emitting angle line laser module for use with high-precision devices. Laser beam is focused at 32.81 ft.(10 meters) to generate best thin laser line from 16.41 ft.(5 meters) to 65.61 ft.(20 meters).
- This module has integrated quartz cylindrical lens, collimating lens, laser diode, and APC driver circuit. APC driver circuit enables constant Laser power output. Please notice- laser modules are not supposed to be sold with any power source, power supply, or wiring terminals. Because modules are simply components, and it means that you have to wire it to your own power source by yourself.
- Includes patented solid brass structure for the best shock resistance and better heat transfer consideration. Aspherical Plastic Lens and Quartz Cylindrical Lens provides tight Line Laser. Emitting angle: >90°. Please notice that it is a laser module, and there is no power supply with it. Notice: Laser modules are NOT laser pens. Laser modules are NOT supposed to be used for commercial use like normal laser pointers.
