790FIB25 25 mm Dia. Standard Interference Bandpass Filter 790nm

The 790FIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to operate at a central wavelength of 790nm. This filter is sourced from Knight Optical, a renowned 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 790FIB25 is cut on at 785nm and cut off at 795nm, providing a narrow bandwidth for optimal performance. The cut-on and cut-off wavelengths are critical specifications for bandpass filters, as they determine the range of wavelengths that the filter will allow to pass.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties. The filter has a thickness of 6.1mm, providing sufficient structural integrity for most applications. The geometry of the filter is circular, a common shape for optical components due to its ease of use in various applications.

The 790FIB25 features a KNI 790DIB coating on both the front and back surfaces. This coating is specifically designed to enhance the performance of the filter, providing improved transmission and blocking characteristics. The coating also provides protection for the filter surface, reducing the risk of damage during handling and use.

The filter is designed with a Thin Lens shape, which is often used in optical systems to minimize optical aberrations. This shape ensures that the filter can be easily integrated into various optical systems without compromising the overall performance of the system.

The 790FIB25 is currently in stock and available for purchase. More information about this filter, including pricing and delivery times, can be found on the Knight Optical website.
