656FIB25 25 mm Dia. Standard Interference Bandpass Filter 656.3nm

The 656FIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to isolate the 656.3nm wavelength. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. In this case, the cut-on wavelength is 651.3nm, and the cut-off wavelength is 661.3nm, making it highly effective in isolating the 656.3nm wavelength.

The 656FIB25 is made from UVFS MAL-1965, a material known for its optical properties and durability. The filter has a thickness of 6.1mm, providing sufficient structural integrity for most applications.

The coating on both the front and back of the filter is KNI 656DIB, which is specifically designed to enhance the filter's performance and durability. The filter's shape is that of a Thin Lens, which is often preferred for its minimal impact on the optical path.

According to the vendor's information, this item is currently in stock and available for immediate purchase. The filter's webpage can be accessed via the following link: https://www.knightoptical.com/stock/default/656nm-interference-bandpass-filter-25mmdiax10nmbw.html
