About the 4 W Mini RGB Laser Module with 7.5 V PSU
This is a professional 4 W full RGB laser module. It is built using brand new laser diodes and high-performance optics.
Laser diodes used in this module:
- 1 W 520 nm Nichia laser diode
- 1.6 W 450 nm Osram laser diode
- 2 x 700 mW 638 nm Ushio laser diode
The dimensions of the module are 110 x 75 x 45 mm. It is possible to mount the module on the base plate using four M4 screws. Due to the housing module is protected against dust which is the main problem inside laser projectors. Also, BK7 window with high transmission anti-reflective coating is used at the output of the module. Total optical power is up to 4000 mW and not less than 3400 mW. Optical beam correction system helped to achieve 1.8 mRad beam at a full angle with minimum power loss.
Using 1 W 520 nm Nichia laser diode instead of 532 nm DPSS assures a long lifetime of the module and better power stability.
The module is controlled by a professional three-channel driver. Each channel is independently controlled by the analog input of (0 - 5 V). Analog input allows for the modulation of the current flowing through the laser diode up to 100 kHz.
The module is powered with Mean Well, 5.4 A, 7.5 V, 40.5 W, the power supply which is included with the module.
Recommendations and requirements
Modulation inputs can be used as TTL inputs with its logic levels of 0 V and 5 V or as an analog input. Analog modulation means that by using 2.5 V on ANG input you get 50% output power, analogically by using 4 V you get 80% output power, etc.
The analog input is protected by a 5V1 Zener diode on occasion there appears the voltage higher than 5 V. Despite everything, this input should not be used with higher voltages.
The output of the driver is protected by Schottky diode which doesn't allow the reverse voltage to appear.
