550DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 550nm

The 550DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light at a central wavelength of 550nm. Sourced from Knight Optical, a reputable vendor in the optical industry, this filter is a part of their extensive catalog, and it is currently in stock.

This filter is of the Bandpass type, which means it allows a specific range of wavelengths to pass through while blocking others. The 550DIB12 is cut on at 545nm and cut off at 555nm, ensuring a tight transmission window around the central wavelength. The Cut-On Wavelength (CWL) is also 550nm, indicating the wavelength at which the filter starts to transmit light.

The 550DIB12 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, making it suitable for various optical applications. The coating on both the front and back surfaces is KNI 550DIB, which contributes to the filter's performance.

The filter's shape is that of a Thin Lens, suggesting that it may have focusing or collimating properties. However, this depends on the specific application and the other optical elements it is used with.
