89-674 25 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 1200nm
The 89-674 is a high-performance shortpass filter, designed and manufactured by Edmund Optics. This filter, with a 25 mm diameter and a thickness of 3 mm, is specifically engineered to transmit light with wavelengths shorter than 1200nm while blocking longer wavelengths.
The filter's construction is based on the UVFS MAL-1965 material, which is known for its robustness and reliability in optical applications. The shortpass functionality is achieved through a precise cut-off at 1200nm, ensuring the filter's effectiveness in various applications.
The 89-674 filter features hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also improves the filter's performance in high-intensity light environments, making it suitable for use in demanding optical systems.
The filter's shape is defined as a Thin Lens, which is a design that minimizes optical aberrations and distortions. This feature, combined with the filter's high-quality construction, ensures optimal performance and precision in its intended applications.
The 89-674 filter is currently in stock and available for purchase through the Edmund Optics website. For more information, please refer to the provided weblink.
