470DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 470nm

The 470DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to center at 470nm. 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 465nm, and the cut-off wavelength is 475nm, making it highly effective in isolating the 470nm light. The Central Wavelength (CWL) of the filter is also 470nm, ensuring optimal performance for its intended use.

The filter is made from UVFS Mal- 1965, a material known for its excellent optical properties. It features a Thin Lens shape, which is beneficial for applications that require minimal optical path deviation. The filter has a thickness of 6.1mm, providing sufficient structural integrity while maintaining minimal impact on the optical path.

The front and back surfaces of the filter are coated with KNI 470DIB, a coating specifically designed for this filter. This coating enhances the filter's performance and durability, ensuring reliable and consistent operation.

The filter is currently in stock and available for immediate purchase through the vendor's website. The provided weblink leads directly to the product page for convenient access.
