84-691 12.5 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=1.5 mm 450nm

The 84-691 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This filter is specifically engineered to transmit light with wavelengths below 450nm, while effectively blocking light of longer wavelengths.

The filter boasts a circular shape with a diameter of 12.5mm, making it suitable for a wide range of optical applications. It has a thickness of 1.5mm, providing robustness and stability in its configuration. The filter is constructed from UVFS Mal-1965, a material known for its excellent optical properties.

The 84-691 filter features hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. This coating also helps to reduce surface reflections, improving the overall efficiency of the optical system.

The filter is designed in a Thin Lens shape, which is a type of optical component that focuses or disperses light waves. This shape allows the filter to be easily integrated into various optical systems, enhancing their performance and functionality.

The filter's catalog number is 84-691, and it is currently in stock. For more information, you can visit the following link: https://www.edmundoptics.com/p/450nm-125mm-diameter-od-4-shortpass-filter-2398d29d/27760/
