89-680 50 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 1300nm

The 89-680 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global provider of optical components. This filter boasts a 50 mm diameter and a thickness of 3 mm, making it a robust and reliable choice for various applications.

The filter is specifically designed for shortpass applications, with a cut-on wavelength of 0 nm and a cut-off wavelength of 1300 nm. This means it allows light with wavelengths shorter than 1300 nm to pass through while blocking light with longer wavelengths. This feature makes it particularly useful in applications such as fluorescence microscopy, where it can help to eliminate unwanted long-wavelength light.

The 89-680 filter is made from UVFS Mal-1965, a high-quality optical material known for its excellent transmission properties and durability. The filter is coated on both sides with EDM 89-672, a hard coating that enhances its resistance to wear and tear, ensuring a long service life.

The filter's thin lens shape allows for easy integration into optical systems, while its circular design provides versatility in terms of mounting and alignment. The filter is currently in stock and available for immediate purchase through the Edmund Optics website.
