Description
The Non-Polarizing Plate Beamsplitters from Rocky Mountain Instrument Co. are expertly designed to divide an incident, monochromatic beam into both reflected and transmitted components, adhering to a specified intensity ratio. These beamsplitters are essential for applications where maintaining the polarization characteristics of the incident beam is crucial. This ensures that the integrity of the polarization is preserved, making them an ideal choice for precision optical systems.
Each plate is meticulously coated on one side with an all-dielectric, non-polarizing, partial reflection coating. This advanced coating technology is paired with a high-efficiency, narrowband anti-reflection coating on the reverse side. This dual-coating approach not only enhances the performance of the beamsplitters but also ensures minimal loss of light and superior clarity in optical applications.
At Rocky Mountain Instrument Co., we pride ourselves on a collaborative service philosophy, working closely with our clients to address even the most technically demanding requirements. By engaging with our customers during the early stages of development, we transition prototype concepts into efficient, manufacturable solutions. Our commitment to excellence and innovation is reflected in every product we offer, ensuring that our clients receive unparalleled quality and performance.
