900DIB25 25 mm Dia. Standard Interference Bandpass Filter 900nm

The 900DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 900nm. 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 light outside this range. The 900DIB25 is cut on at 895nm and cut off at 905nm, ensuring a tight bandpass performance around the central wavelength. The Cut-On Wavelength (CWL) is also 900nm, indicating the wavelength at which the filter starts to transmit light.

The filter is made of UVFS Mal-1965, a material known for its optical properties. It has a circular base shape, a common form factor for optical components due to its ease of integration into various 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 900DIB. This coating is specifically designed to enhance the filter's performance, ensuring optimal transmission within the passband and high attenuation outside it.

The filter's shape is described as a Thin Lens, indicating its potential use in focusing or collimating light beams. This feature adds versatility to the filter, making it suitable for a wide range of applications.
