89-678 50 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 1200nm

The 89-678 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 1200 nm. This means it allows light with wavelengths shorter than 1200 nm to pass through while blocking light with longer wavelengths. This feature makes it particularly useful in applications where the detection of short wavelengths is crucial.

The 89-678 filter is coated with EDM 89-670 on both the front and back surfaces. This hard coating enhances the filter's durability and resistance to wear and tear, ensuring long-lasting performance. The filter's thin lens shape further contributes to its versatility and ease of integration into various optical systems.
