700FCQ5000 50 mm Dia. Cold Mirror 800-1200nm

The 700FCQ5000 is a high-quality cold mirror filter, sourced from the renowned optical component vendor, Knight Optical. This filter, with a diameter of 50 mm, is designed to reflect infrared radiation while transmitting visible light, making it ideal for applications where heat management is crucial.

The filter is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and durability. It has a thickness of 3.3 mm, providing robustness and stability. The filter's geometry, including its diameter and thickness, is designed to ensure optimal performance in its specific application.

The 700FCQ5000 features a coating on both the front and back surfaces, specifically the KNI CRV1-1 coating. This coating enhances the filter's performance by ensuring efficient reflection of infrared radiation and transmission of visible light. The coating also provides protection to the filter's surface, enhancing its longevity and reliability.

The filter is classified as a hot/cold mirror, a type of optical filter that separates thermal radiation from visible light. It is designed to operate at a central wavelength of 588 nm, making it suitable for a wide range of applications.

In terms of shape, the filter is designed as a thin lens, which is often used in optical systems to reduce weight and thickness while maintaining optical performance. This design makes the filter easy to integrate into various optical systems.

The 700FCQ5000 is currently in stock and available for immediate purchase from Knight Optical's website. With its high-quality materials, advanced coating, and precise geometry, this filter is an excellent choice for any application that requires effective heat management and efficient light transmission.
