480DIB25 25 mm Dia. Standard Interference Bandpass Filter 480nm
The 480DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to center at a wavelength of 480nm. 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 475nm, and the cut-off wavelength is 485nm, making it highly effective in isolating the 480nm 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 filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing optical distortions.
The coating on both the front and back surfaces of the filter is KNI 480DIB. This coating is specifically designed to enhance the filter's performance, ensuring high transmission efficiency and excellent wavelength selectivity.
The filter's shape is described as a Thin Lens, indicating that it has been designed to minimize optical aberrations and ensure optimal performance in various optical systems. This filter is currently in stock and available for immediate purchase through the vendor's website.
