320FIB25 25 mm Dia. Interference Bandpass Filter 214-320nm

The 320FIB25 is a 25 mm diameter Interference Bandpass Filter, specifically designed to transmit light in the 214-320nm wavelength range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.

The filter is made of UVFS Mal-1965, a material specifically chosen for its optical properties in the ultraviolet spectrum. It has a base shape of a circle, ensuring uniform transmission across the entire surface. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unwanted optical effects.

The 320FIB25 features a thin lens shape, optimized for use in optical systems where minimal thickness is required. The cut-on wavelength is 315nm, and the cut-off wavelength is 325nm, ensuring a tight bandpass in the desired region. The center wavelength (CWL) is 320nm, the precise point of maximum transmission.

The filter's front and back surfaces are coated with KNI 320fib, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, providing improved transmission and durability.

The 320FIB25 is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.knightoptical.com/stock/default/320nm-interference-bandpass-filter-25mmdiax10nmbw.html.
