2. SainSmart FL55 Laser Module 455nm Blue-Violet Light Fixed Focus Laser Module Kit for Genmitsu CNC Machine 3018-MX3/3018-PROVer
Feature
Application: The laser module is ideal for engraving, cutting, scribing, and drilling. Desired patterns can be made easily on the wood or plastic by this unit. This module is only compatible with 3018-MX3/3018-PROVer, but not compatible with 1810-PRO/3018/3018-PRO.Fixed Focus: The fixed focus distance is 20mm. Compared with the adjustable focus laser module, the light spot of the fixed focus laser module is smaller. At the same power, the fixed focus laser module can cut 3mm linden wood in one pass, not possible with current adjustable laser modules.
Longer Service Life: The fixed focus laser module can work at full power for 8 hours without any light decay. The service life can be up to 10,000 hours.
Excellent Heat Dissipation: Equipped with a large aluminum heatsink and cooling fan, this can help the heat dissipate fast and ensure the laser module works continuously.
Industrial Grade Design: It is designed for industrial laser engraving machines, it adopts an intelligent feedback control circuit, external ACC constant current driving Mode. Featuring reliability, high stability, high efficiency, low noise, and excellent laser beam quality.
