589DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 589.6nm

The 589DIB12 is a circular Bandpass Filter with a diameter of 12.5 mm and a thickness of 6.1 mm, sourced from the reputable vendor Knight Optical. This filter is designed to transmit light within a specific range of wavelengths, making it an essential component in various optical applications.

The filter's primary function is centered around the wavelength of 589.6 nm, with a cut-on wavelength of 584.6 nm and a cut-off wavelength of 594.6 nm. This precise wavelength selection is facilitated by the front and back coatings, both bearing the designation KNI 589DIB. These coatings are specifically engineered to allow the transmission of light within the desired wavelength range while blocking out unwanted spectral components.

The filter's geometry is that of a Thin Lens, suggesting its potential use in focusing or collimating light beams. The material used in the fabrication of this filter is UVFS MAL-1965, a detail that may be crucial for users considering the filter's interaction with other optical elements in their systems.

The filter is currently in stock and available for immediate purchase through the vendor's website. For more information, users are encouraged to visit the provided weblink: https://www.knightoptical.com/stock/default/589nm-interference-bandpass-filter-12-5mmdiax10nmbw.html
