89-672 12.5 mm Dia. Hard Coated High Performance OD 4.0 Shortpass Filter; t=3 mm 1300nm

The 89-672 is a high-performance shortpass filter, designed and manufactured by Edmund Optics, a leading global provider of optical components. This filter boasts a 12.5 mm diameter and a thickness of 3 mm, making it a versatile choice for various applications.

The filter is specifically designed for use in the 1300nm wavelength range, with a cut-on wavelength of 0nm and a cut-off wavelength of 1300nm. This makes it ideal for applications that require the blocking of longer wavelengths while allowing shorter wavelengths to pass through.

The 89-672 features a 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 and performance of the filter.

The filter's geometry is defined by its circular shape and thin lens design, which contributes to its compact size and light weight. This makes it a convenient choice for applications where space and weight are at a premium.

The filter is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. This ensures that users can quickly and easily acquire this high-quality optical component for their specific needs.
