86-652 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 400nm

The 86-652 is a Bandpass Filter, specifically designed for use in optical systems where precise wavelength selection is required. This filter, sourced from Edmund Optics, features a circular shape with a diameter of 25 mm and a thickness of 3.5 mm. The filter is made from UVFS Mal-1965 material, ensuring durability and reliability in a variety of applications.

The Bandpass Filter has a central wavelength (CWL) of 400nm, making it ideal for use in systems where blue light is the primary focus. The filter's cut-on wavelength is 387.5nm, and the cut-off wavelength is 412.5nm, providing a narrow bandwidth that helps to reduce unwanted noise and improve signal clarity.

The 86-652 is coated with EDM 86-640 on both the front and back surfaces, enhancing its performance and longevity. This hard coating provides excellent environmental stability and resistance to scratching and abrasion. The filter's thin lens shape further contributes to its versatility and ease of integration into various optical systems.
