405DIB12 12.5 mm Dia. Standard Interference Bandpass Filter 405nm
The 405DIB12 is a 12.5 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 405nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The 405DIB12 is cut on at 400nm and cut off at 410nm, making it ideal for applications that require narrow-band light transmission around the 405nm wavelength.
The filter is made from UVFS Mal- 1965, a material specifically chosen for its optical properties in the ultraviolet spectrum. It has a thickness of 6.1mm, which contributes to its durability and overall performance.
The coating on both the front and back surfaces of the filter is KNI 405DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by ensuring high transmission within the passband and low transmission outside it.
The 405DIB12 is shaped as a Thin Lens, which means it can be used in optical systems where a lens-like element is required. This versatile filter is currently in stock and can be purchased directly from Knight Optical's website.
