Notification:
1. The Semiconductor Optoelectronic products are particulary sensitive of ESD (electro-static discharge), it's recommended to 
    use grounded anti-static wrist straps and grounded anti-static mats before handling the products. 
2. Never plug or unplug the products under a living circuit, setting the current supply to zero before switching on or switching 
    off the laser diode.
3. Always take anti-static measures to storage the products when not in use.
