84-704 25 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 450nm

The 84-704 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This filter boasts a 25 mm diameter and a thickness of 3 mm, making it a versatile and robust option for various applications.

The filter is constructed with a base shape of a circle, ensuring uniform light transmission and minimal distortion. It is made from UVFS Mal-1965, a material known for its excellent optical properties and durability. The filter's shortpass characteristics are defined by its cut-on wavelength at 0 nm and a cut-off wavelength of 450 nm. This means it allows light of shorter wavelengths to pass through while blocking light of longer wavelengths, making it ideal for applications such as fluorescence microscopy, laser spectroscopy, and other scenarios where short wavelength light needs to be isolated.

The 84-704 filter features hard coating on both the front and back surfaces, enhancing its durability and resistance to scratches and other forms of damage. This coating also helps to reduce surface reflections, improving the filter's overall efficiency and performance. The filter's shape is classified as a thin lens, further contributing to its versatility and ease of integration into various optical systems.
