Non-Polarizing Beamsplitter Plate
Non-polarizing beamsplitter plates are designed to split incident light into multiple beam paths while maintaining the original polarization state of the input source. Operating across a broad spectral range from the ultraviolet (UV) to the infrared (IR) (250-2600 nm), these plates utilize an anti-reflective (AR) coating on the back surface to minimize secondary ghost reflections to less than 0.25%.
Applications:
- Laser interferometry and optical coherence tomography (OCT) for splitting beam paths without inducing polarization-dependent phase shifts
- Microscopy and fluorescence imaging for directing specific light ratios to multiple detectors or eyepieces
- Optical beam routing and diagnostic systems where maintaining the input polarization state is required
Specifications & Options:
- Spectral range from 250nm to 2600nm (UV to IR bands)
- Polarization dependence of <10% (typically <5%)
- Surface quality of <10-5 scratch-dig and flatness of <λ/10 at 633nm to limit wavefront distortion
- AR coating on the back face reducing secondary reflections to <0.25%
