790DIB25 25 mm Dia. Standard Interference Bandpass Filter 790nm
The 790DIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 790nm wavelength range while blocking light at other 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. It has a base shape of a circle, a common choice for its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unwanted optical effects.
The 790DIB25 has a cut-on wavelength of 785nm and a cut-off wavelength of 795nm, meaning it begins transmitting light at 785nm and stops transmitting at 795nm. The central wavelength (CWL) of this filter is 790nm, the point of maximum transmission. This makes it ideal for applications that require narrowband filtering around this wavelength.
Both the front and back surfaces of the filter are coated with KNI 790DIB, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance, ensuring high transmission and blocking efficiency. The filter's shape is a thin lens, further optimizing its optical properties for use in various applications.
The 790DIB25 is currently in stock and available for immediate purchase. For more information, including pricing and technical specifications, please refer to the provided weblink.
