89-677 50 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 1150nm

The 89-677 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This filter boasts a 50 mm diameter and a thickness of 3 mm, making it suitable for a wide range of applications.

The filter is specifically designed to pass wavelengths of 1150nm and below, while effectively blocking wavelengths above this cutoff. This feature makes it an ideal choice for applications that require the removal of unwanted longer wavelengths, such as infrared rejection in imaging systems.

The 89-677 filter is coated with EDM 89-669 on both the front and back surfaces, enhancing its durability and performance. This hard coating provides excellent resistance to environmental factors, ensuring the filter maintains its optical properties over time.

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