380DIB50 50 mm Dia. Standard Interference Bandpass Filter 380nm

The 380DIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to pass waves within the 380nm wavelength range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical elements.

The filter is of the Bandpass type, which means it allows a specific range of wavelengths to pass through while blocking others. This is particularly useful in applications where a narrow range of wavelengths needs to be isolated or emphasized. The 380DIB50 is cut on at 375nm and cut off at 385nm, ensuring a tight bandpass around the central wavelength of 380nm.

The filter is made from UVFS MAL-1965, a material known for its excellent optical properties in the ultraviolet range. The filter has a thickness of 6.1mm, providing sufficient mechanical stability for most applications.

The front and back of the filter are coated with KNI 380DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing unwanted reflections and increasing transmission within the passband.

The filter is shaped as a Thin Lens, which can be beneficial in applications where the filter needs to focus or collimate light. The lens shape also minimizes optical aberrations, ensuring high-quality imaging or signal transmission.
