320FCS2500 25 mm Dia. Colour Glass Bandpass Filter 320nm
The 320FCS2500 is a 25 mm diameter Color Glass Bandpass Filter, specifically designed to pass light in the 320nm wavelength range while blocking 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 shape for filters due to its ease of use and versatility. The filter's geometry includes a diameter of 25mm and a thickness of 3mm, providing a sturdy yet compact design.
The 320FCS2500 features physical data that defines its cut-on wavelength at 245nm and its cut-off wavelength at 390nm. This means that it begins to transmit light at 245nm and stops transmitting at 390nm, effectively filtering out unwanted wavelengths.
The filter is coated with KNI 320FCS on both the front and back surfaces, a coating that enhances its performance in the specified wavelength range. The filter's shape is thin lens, a design that minimizes optical aberrations and ensures optimal light transmission.
