The LBTEK 45° beam splitter compensator is an optical window used to compensate for phase differences between beams. It is often paired with beam splitters made of the same substrate material and thickness, ensuring that all beams pass through substrates of identical thickness. This minimizes phase discrepancies between split beams, thereby yielding superior experimental results. Depending on the wavelength range, the substrate materials of these compensators typically feature low refractive index, high uniformity, and low thermal expansion coefficients. Currently, LBTEK offers 45° beam splitter compensators with UV-grade fused silica substrates suitable for the 250 nm–450 nm wavelength range. These are available in two size options: circular (1-inch diameter) and rectangular (25 mm × 36 mm). LBTEK's 45° beam splitter compensators deliver excellent performance, efficiently eliminating phase differences between beams. Additionally, LBTEK provides various customization services, including tailored materials, wavelength compatibility, and dimensions/thickness specifications. For specific customization requirements, please contact LBTEK Technical Support.
