488DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 488nm

The 488DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed for a central wavelength of 488nm. 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 other wavelengths. In this case, the cut-on wavelength is 483nm, and the cut-off wavelength is 493nm, making it ideal for applications that require narrow-band light in the 488nm range.

The 488DIB12 filter is made from UVFS Mal- 1965, a material known for its optical properties in the ultraviolet, visible, and shortwave infrared regions. The filter has a thickness of 6.1mm, and its shape is that of a Thin Lens, which is often used in optical systems to reduce spherical aberration.

The front and back of the filter are coated with KNI 488DIB, a coating that enhances the filter's performance and durability. The filter's physical data, including its catalog number, weblinks, and weblink status, are all provided, ensuring users have access to all the information they need to make an informed decision.
