The TPJ high-precision polarizing beam splitter prism is a further improvement and optimization of the process based on the high-power polarizing beam splitter prism produced by our company. The optimized projection depolarization ratio can reach higher values such as 1000, 2000, 3000, 5000, while meeting the reflection depolarization requirements of higher values such as 200, 500, 1000, 2000. The deflection of the projected and reflected light rays is better than 5 seconds or more, and the projected wavefront is also better than 1/10 or more of the incident wavefront. The dimensional tolerance can reach ± 0.01mm, and it can also withstand extremely high laser damage thresholds, making it the preferred choice for high-end customized customer groups.
