589DIB25 25 mm Dia. Standard Interference Bandpass Filter 589.6nm

The 589DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 589.6nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.

The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking out light from other wavelengths. This particular filter is cut on at 584.6nm and cut off at 594.6nm, ensuring a narrow band of light centered at 589.6nm can pass through.

The filter is made from UVFS MAL-1965, a material known for its optical properties. It has a circular base shape and a thickness of 6.1mm, which is typical for this type of filter. The coating on both the front and back surfaces of the filter is KNI 589DIB, which is specifically designed for this filter's unique properties.

The geometry of the filter includes a diameter of 25mm, making it suitable for a wide range of optical applications. The physical data of the filter includes a central wavelength (CWL) of 589.6nm, which is the wavelength at which the filter is designed to transmit light most efficiently.

The filter is shaped as a Thin Lens, which is a type of lens with a short focal length compared to its diameter. This shape is often used in optical systems where a wide field of view and low distortion are required.
