Details:
1. To correct a laser beam. The axis of the laser beam been enlarged for achieve the required beam shape.
2. To reshape the laser beam from an oval to close a round.(The modify result also depends on the diode’s type)
3. This Prisms Pair especially suitable for high power laser diode. Such as 405nm/445nm/450nm/465nm/470nm high power output blue laser diodes. It can help those diode’s beam shape from a line to a near round dot in a short distance.
4. With the prisms the expansion ratio of 2:1 to 6:1 can be achieved by expanded one of the axis twice then the divergence will be halved. This will help you get more uniform length of the axis. The slow-expanding-axis remains unaffected status.
5. The prisms have anti-reflective coating.
6. With high quality optical materials, the laser power loss is in a very lower range.
