Description
Plate Beamsplitters by Rocky Mountain Instrument Co. are expertly engineered to divide an incident, monochromatic beam into reflected and transmitted components with a precise intensity ratio. These optical components are essential in various high-precision applications where the control of light is paramount. The beamsplitters feature a specialized coating on one side that is sensitive to polarization, allowing for partial reflection, while the reverse side is treated with a high-efficiency, narrowband anti-reflection coating. This dual-coating approach ensures optimal performance and efficiency in light management.
Crafted from a range of materials including BK7, UVFS, FS, ZnSe, Ge, and Chalcogenide glass, these beamsplitters are designed to meet rigorous industry standards. The meticulous attention to detail in the manufacturing process guarantees exceptional surface quality and precision. The plate beamsplitters are capable of handling a variety of wavelengths with outstanding surface figures and quality, ensuring minimal light distortion and maximum clarity.
RMI's commitment to excellence is reflected in the precise specifications of their plate beamsplitters. With a diameter tolerance of +0.000", –0.010" and thickness tolerance of ±0.010", these components offer consistent performance that meets the demands of the most challenging optical systems. The wedge angle is maintained at ≤ 3 arc minutes, and the bevels are crafted to 0.010" - 0.030" at a 45° angle, ensuring seamless integration into any optical setup. The clear aperture, which constitutes the central 85% of the diameter, provides ample space for light passage, while the anti-reflection coating ensures that reflectance is kept to a minimum.
Rocky Mountain Instrument Co. prides itself on its collaborative approach, working closely with customers to transform prototype concepts into manufacturable solutions. This dedication to customer satisfaction and technical excellence makes RMI a trusted partner in the field of optics.
