370FIB50 50 mm Dia. Standard Interference Bandpass Filter 370nm

The 370FIB50 is a 50 mm diameter Standard Interference Bandpass Filter, specifically designed to pass light in the 370nm 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 light to pass through a specific range of wavelengths while blocking out other wavelengths. This is achieved through the use of a thin-film coating on the filter's surface, which reflects or transmits light depending on its wavelength. In this case, the 370FIB50 has a Cut-On wavelength of 365nm and a Cut-Off wavelength of 375nm, making it ideal for applications that require narrow-band light in the ultraviolet spectrum.

The filter is made from UVFS MAL-1965, a material specifically designed for use in ultraviolet applications. It has a circular shape, with a diameter of 50mm and a thickness of 6.1mm, making it suitable for use in a variety of optical systems.

The 370FIB50 is coated on both the front and back surfaces with KNI 370DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, ensuring high transmission and low reflection in the desired wavelength range.

The filter is available in a Thin Lens shape, which is characterized by a flat front surface and a curved back surface. This shape is often used in optical systems where a flat input beam is required, such as in imaging systems or laser applications.

According to the vendor, the 370FIB50 is currently in stock and can be purchased directly from their website. The filter comes with a catalog number (370FIB50) for easy identification and ordering.
