760FIB25 25 mm Dia. Standard Interference Bandpass Filter 760nm

The 760FIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 760nm wavelength range while blocking unwanted light from adjacent wavelengths. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties in the 760nm range. It features a circular base shape, with a thickness of 6.1mm, providing durability and stability in various optical systems.

The 760FIB25 has a cut-on wavelength of 755nm and a cut-off wavelength of 765nm, ensuring a tight bandpass around the desired 760nm wavelength. The central wavelength (CWL) is also 760nm, indicating the peak transmission wavelength.

Both the front and back surfaces of the filter are coated with KNI 760DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, providing a high transmission rate and excellent blocking capabilities.

The filter's shape is described as a Thin Lens, suggesting 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 provided weblink.
