458DIB25 25 mm Dia. Standard Interference Bandpass Filter 457.9nm

The 458DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light 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 of the Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out light from other regions of the spectrum. This is particularly useful in applications where a narrow range of wavelengths needs to be isolated or emphasized.

The 458DIB25 is made from UVFS Mal-1965, a material specifically chosen for its optical properties. It has a base shape of a Circle, making it suitable for a wide range of applications where a circular filter is required.

The filter's physical data includes a cut-on wavelength of 452.9nm and a cut-off wavelength of 462.9nm. This means that it begins to transmit light at 452.9nm and stops transmitting at 462.9nm. The central wavelength of 457.9nm falls within this range, right at the center of the transmission window.

The coating on both the front and back of the filter is KNI 458DIB. This coating is designed to enhance the filter's performance and durability. The filter has a thickness of 6.1mm, providing sufficient structural integrity for most applications.

The 458DIB25 is available in a Thin Lens shape, which is beneficial in applications where a thin, lightweight filter is required. This filter is currently in stock and can be purchased directly from Knight Optical via the provided weblink.
