86-659 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 750nm

The 86-659 is a Bandpass Filter, specifically designed for applications requiring precise wavelength selection. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 25 mm and a thickness of 3.5 mm, making it suitable for various optical systems.

This filter is made from UVFS Mal-1965 material, a common choice for its excellent optical properties. The filter's primary function is to allow light within a specific wavelength range to pass through while blocking other wavelengths. The 86-659 is designed to pass light at a central wavelength (CWL) of 750 nm, with a cut-on wavelength of 737.5 nm and a cut-off wavelength of 762.5 nm. This means it will pass wavelengths between these two points, making it ideal for applications that require narrow-band light.

The 86-659 is hard coated on both the front and back, enhancing its durability and resistance to wear and tear. The coating material used is EDM 86-647, which is known for its high-quality performance and reliability. The filter's shape is that of a thin lens, further expanding its potential applications.

The filter's availability and in-stock status make it a reliable choice for immediate use in various projects. For more information, users can refer to the provided weblink, which leads to the product's page on the Edmund Optics website.
