488DIB25 25 mm Dia. Standard Interference Bandpass Filter 488nm

The 488DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 488nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.

The filter is a 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 483nm, and the cut-off wavelength is 493nm, making it highly effective in isolating the 488nm wavelength.

The filter is made from UVFS Mal- 1965, a material known for its optical properties and durability. It has a circular base shape, a common design for filters due to its ease of integration into various optical systems.

The physical data of the filter includes a center wavelength (CWL) of 488nm, which is the wavelength at which the filter has its maximum transmission. The filter's geometry includes a diameter of 25mm and a thickness of 6.1mm, providing a robust and stable platform for optical applications.

The coating on both the front and back surfaces of the filter is KNI 488DIB. This coating is designed to enhance the filter's performance and durability, ensuring reliable operation in various environments.

The filter's shape is Thin Lens, which suggests it may have some light focusing properties. However, this should be confirmed with the vendor or through further technical specifications.

The filter is currently in stock and available for purchase through the vendor's website, as indicated by the 'Valid - in stock' status in the item data.
