62-634 12.5 x 12.5 mm Dielectric Cold Mirror; 45 deg AOI 425-1200nm

The 62-634 is a high-quality cold mirror filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for use in optical systems that require the separation of visible and infrared light. The cold mirror has a dielectric coating, which is highly reflective for infrared light and transmissive for visible light, making it ideal for applications such as thermal imaging, spectroscopy, and beam combining.

The filter has a base shape of 12.5 x 12.5 mm, making it suitable for use in compact optical systems. It is made from borofloat33, a type of borosilicate glass known for its excellent optical properties and durability. The filter has a thickness of 1.1 mm, which contributes to its robustness and stability in optical systems.

The 62-634 filter features a 45-degree angle of incidence (AOI), which is designed to maximize its performance in optical systems where light enters the filter at a 45-degree angle. The filter's coating, both on the front and back surfaces, is a proprietary dielectric coating, designated as 'edm 62-634'. This coating provides high reflectivity for infrared light and high transmissivity for visible light, ensuring optimal performance in its intended applications.

The filter is currently in stock and available for immediate purchase from the Edmund Optics website. It is categorized as a Hot/Cold Mirror under the Filter type, and it has a wavelength of 588 nm. The filter's geometry, including its width, height, and thickness, is precisely controlled during manufacturing to ensure consistent performance and compatibility with other optical components.
