330DIB25 25 mm Dia. Standard Interference Bandpass Filter 330nm

The 330DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to pass light in the 330nm wavelength range while blocking light at other wavelengths. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is made from UVFS MAL-1965, a material specifically chosen for its optical properties in the ultraviolet spectrum. It has a base shape of a circle, a common choice for its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unwanted optical effects.

The 330DIB25 features a cut-on wavelength of 325nm and a cut-off wavelength of 335nm, meaning it begins to pass light at 325nm and stops passing light at 335nm. The central wavelength (CWL) of this filter is 330nm, indicating the wavelength at which the filter has its maximum transmittance.

Both the front and back surfaces of the filter are coated with KNI 330DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance and durability, ensuring reliable operation in various environments.

The filter's shape is described as a Thin Lens, suggesting it may have lens-like properties, such as focusing or collimating light. However, this should be confirmed with the vendor or in the filter's technical specifications.
