Description
Non-Polarizing Plate Beamsplitters are a sophisticated optical component designed to divide an incident, monochromatic beam into its reflected and transmitted components according to a specified intensity ratio. These beamsplitters are crucial in applications where it is essential to maintain the polarization characteristics of the incident light. The design incorporates a plate with a dielectric, non-polarizing, partial reflection coating on one side and a high-efficiency, narrowband anti-reflection coating on the other. This meticulous engineering ensures minimal alteration to the polarization state of the light, making these beamsplitters ideal for precision optical applications.
The construction of these beamsplitters involves high-quality materials such as BK7, UVFS, and ZnSe, which are chosen for their superior optical properties. The angle of incidence is precisely set at 45º to optimize performance. Each surface is crafted to meet stringent surface figure specifications, ensuring exceptional optical clarity and minimal distortion. The careful selection of materials and coatings results in a component that delivers reliable performance across a range of optical wavelengths.
At Rocky Mountain Instrument Co., the production of Non-Polarizing Plate Beamsplitters is guided by a commitment to quality and precision. The surface quality is maintained to exacting standards, with specific tolerances for diameter, thickness, and wedge angles. This attention to detail ensures that each beamsplitter meets the rigorous demands of advanced optical systems. The collaborative approach of RMI allows for the seamless transition from prototype to production, addressing even the most technically challenging requirements with innovative solutions.
