Page 4: Safety Requirements
1. Safety requirements • All safety instructions must be followed. • All rules and regulations concerning the safe operation of lasers must be known and applied while installing and operating motorised laser power attenuator. • Even when wearing safety glasses avoid eye contact with direct or scattered laser light while assembling, installing and operating the device. -
Page 5: Operation Principle
2.2. Features and advantages 2. Operation principle • Integrated controller LPA-A consists of zero-order half-waveplate and High contrast Brewster type thin film polariser. • Absolute position encoder - no homing required Zero-order half-waveplate rotates the polarisation. Brewster • High accuracy - ±0.005 deg type thin polariser passes P-polarised and reflects the S- (less than ±0.01% of laser power) polarised laser beam. -
