Description
Non-Polarizing Plate Beamsplitters from Rocky Mountain Instrument Co. are expertly crafted to divide an incident, monochromatic beam into reflected and transmitted components with a specific intensity ratio. These beamsplitters are essential for applications requiring the preservation of the polarization characteristics of the incident beam. The design features a plate that is meticulously coated on one side with an all-dielectric, non-polarizing, partial reflection coating. On the reverse side, a high-efficiency, narrowband, anti-reflection coating is applied to enhance performance.
These beamsplitters are constructed using high-quality materials such as BK7, UVFS, and ZnSe, ensuring superior optical performance and durability. They are engineered to operate at an angle of incidence of 45º, which is optimal for many optical systems. The surface quality is maintained to the highest standards, with specifications such as λ/20 at 632 nm for BK7 and UVFS, and λ/40 at 10.6 µm for ZnSe, ensuring minimal wavefront distortion.
Rocky Mountain Instrument Co. prides itself on a collaborative approach with customers, addressing even the most technically challenging requirements. By engaging with clients early in the development process, RMI transitions prototype concepts into efficient, manufacturable solutions. This commitment to excellence and innovation makes RMI a trusted partner in the field of optics.
