Feature: 1. Widely Compatible Design: ?It can be installed on a variety of brand machines, such as ortur laser master 2 pro s2, laser master 2 S2, laser master 3. 2. 60W Effect Spot Compressed Laser: 24V LU2-10A with real 10W laser power. It has an ultra-thin square laser focus, and its cutting penetration and accuracy are twice of ordinary lasers. Even in the field of spot lasers, LU2-10A has finer engraving marks and stronger cutting and penetration capabilities. It can cut 20mm thick wood boards and engrave ceramics and acrylics, which is almost beyond the effect of 60W CO2 laser. 3. Fast Fixed-focus Design: Combines a fixed focus lens and a sliding design. You only need to slide the laser and tighten the screws to complete focusing. This makes the use of the laser very simple. Using it on different machines does not affect its sliding fixed focusing function. 4. Circle Eye-conservation Cover Design: The laser filter cover filters 98% of the ultraviolet light to the eyes. You and the people around you can watch laser engraving from all angles without wearing goggles. At the same time, it can prevent animals from catching the laser spot. 5. General 24V/PWM Modulation Board: It is the latest 24V/PWM modulation board, which can be adapted to common GRBL or CNC motherboards.
