1140DIB25 25 mm Dia. Standard Interference Bandpass Filter 1140nm
The 1140DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 1140nm. 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. This particular model has a cut-on wavelength of 1131.25nm and a cut-off wavelength of 1148.75nm, ensuring a narrow and precise bandwidth for your optical system.
The 1140DIB25 is made from UVFS Mal-1965, a material known for its optical properties and durability. It features a Thin Lens shape, which is beneficial for applications where space is a constraint. The filter has a thickness of 6.1mm, providing sufficient structural integrity while minimizing optical distortions.
The front and back surfaces of the filter are coated with KNI 1140DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency.
The filter is currently in stock and available for immediate purchase through the vendor's website. A direct link to the product page is provided for your convenience.
