440DIB25 25 mm Dia. Standard Interference Bandpass Filter 440nm

The 440DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 440nm range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.

The filter is of the Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. In this case, the cut-on wavelength is 435nm, and the cut-off wavelength is 445nm, making it ideal for applications that require narrow-band light in the 440nm range.

The 440DIB25 is made from UVFS MAL-1965, a material known for its excellent optical properties. It has a circular base shape and a thickness of 6.1mm, making it suitable for a wide range of optical systems.

The filter's coating is KNI 440DIB on both the front and back surfaces, which enhances its performance and durability. The shape of the filter is thin lens, which is beneficial for applications that require minimal added thickness.

This filter is currently in stock and available for purchase on Knight Optical's website. For more information, you can visit the following link: https://www.knightoptical.com/stock/default/440nm-interference-bandpass-filter-25mmdiax10nmbw.html
