400DIB25 25 mm Dia. Standard Interference Bandpass Filter 400nm

The 400DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 400nm wavelength range. Sourced from Knight Optical, a reputable vendor in the optical industry, this filter is a crucial component for various optical systems.

The filter is made of UVFS MAL-1965 material, a unique substrate known for its excellent optical properties. It features a circular base shape, with a diameter of 25mm and a thickness of 6.1mm, making it compatible with a wide range of optical setups.

The 400DIB25 is a Bandpass Filter, meaning it allows light in a specific range of wavelengths to pass through while blocking out other wavelengths. In this case, it is cut on 395nm and cut off at 405nm, ensuring a tight 400nm center wavelength (CWL). This precise wavelength selection is crucial in many applications, such as fluorescence microscopy, spectroscopy, and laser systems.

The filter is coated with KNI 400DIB on both the front and back surfaces, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, providing improved transmission and blocking capabilities. The filter's shape is a Thin Lens, further expanding its potential applications.
