The Beam sampler DOEs are used to monitor high power lasers.
A Laser Beam Sampler allows the high power beam (zero order) to propagate undisturbed along the optical axis, but produces two side beams with low energy. These two sample beams are located to the left and right of the main beam (-1 and +1 orders), and are characterized by a given separation angle between them and by a sample power ratio. It is relatively easy to modify the sampling ratio upon a request of the customer.
FEATURES:
- Works with single or multi mode input beams
- High power threshold
- Exact copy of input beam shape
- Custom sampled ratio and separation angle
- Wavelengths from UV to IR
- Insensitive to X-Y-Z displacements and beam size
APPLICATIONS:
- Monitoring
- Inline beam profiler
