458DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 457.9nm
The 458DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 457.9nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
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 452.9nm, and the cut-off wavelength is 462.9nm. This precise wavelength selection is crucial in various applications where controlling the spectral content of light is essential.
The 458DIB12 is made from UVFS Mal- 1965, a material known for its optical properties. The filter has a Thin Lens shape, which is often preferred in optical systems due to its minimal thickness and weight. The geometry of the filter includes a diameter of 12.5mm and a thickness of 6.1mm, making it suitable for use in compact optical systems.
The filter's front and back surfaces are coated with KNI 458DIB, a coating that enhances its performance in specific wavelength ranges. This coating is applied during the manufacturing process, ensuring the filter's durability and longevity.
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 easy access and ordering.
