390DIB50 50 mm Dia. Standard Interference Bandpass Filter 390nm

The 390DIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light at a central wavelength of 390nm 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 circular base shape, a standard geometry in optical applications due to its ease of use and integration. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing optical distortions.

The 390DIB50 features a cut-on wavelength of 385nm and a cut-off wavelength of 395nm, meaning it begins transmitting light at 385nm and stops transmitting at 395nm. The central wavelength of 390nm falls within this range, ensuring high transmission efficiency at this specific wavelength.

The filter's coating is a crucial aspect of its performance. Both the front and back surfaces are coated with KNI 390DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, ensuring high transmission at the desired wavelength and low transmission at others.

The filter's shape is described as a Thin Lens, indicating that it has been designed to focus or collimate light. This feature can be beneficial in various applications, such as laser systems or imaging devices.
