470DIB25 25 mm Dia. Standard Interference Bandpass Filter 470nm
The 470DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 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 light outside this range. The 470DIB25 is cut on at 465nm and cut off at 475nm, ensuring a narrow and precise bandwidth for your optical system. The central wavelength (CWL) of this filter is 470nm, providing a peak transmission within the specified range.
The filter is made of UVFS MAL-1965 material, a durable and reliable option for optical applications. It features a Thin Lens shape, which is beneficial for applications where space is a constraint. The filter has a thickness of 6.1mm, providing sufficient structural integrity while minimizing unnecessary bulk.
The front and back of the filter are coated with KNI 470DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance and durability, ensuring optimal transmission and blocking properties over time.
The 470DIB25 is currently in stock and available for purchase on Knight Optical's website. For more information, please refer to the provided weblink.
