785FIJ25 25 mm Dia. Standard Interference Bandpass Filter 785nm

The 785FIJ25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 785nm. 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 out unwanted light from other spectral regions. The cut-on wavelength is 780nm, and the cut-off wavelength is 790nm, providing a narrow bandwidth that aids in the reduction of unwanted light and increases signal-to-noise ratio.

The filter is made from UVFS Mal-1965, a material known for its excellent optical properties. It features a circular base shape and a thickness of 6.1mm, making it suitable for a wide range of optical applications. The coating on both the front and back surfaces is KNI 785DIJ, which enhances the filter's performance and durability.

The 785FIJ25 is designed in a Thin Lens shape, allowing it to be easily integrated into various optical systems. According to the vendor, this item is currently in stock and the associated web link provided is valid.
