420FIB12 12.5 mm Dia. Standard Interference Bandpass Filter 420nm
The 420FIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to pass light in the 420nm range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is a Bandpass type, which means it allows light to pass through a specific range of wavelengths while blocking out other wavelengths. In this case, the 420FIB12 is designed to cut on at 415nm and cut off at 425nm, making it ideal for applications that require precise filtering in the blue spectrum.
The filter is made from UVFS Mal- 1965, a material known for its excellent optical properties. It has a circular base shape and a thickness of 6.1mm, making it suitable for a wide range of optical systems. The coating on both the front and back of the filter is KNI 420DIB, which contributes to its high performance.
The 420FIB12 is shaped as a Thin Lens, which means it can be used in optical systems where a lens-like element is required. This filter is currently in stock and available for immediate purchase through the vendor's website.
