400FS70-50 50mm Dia. 400nm Bandpass Filter, HBW 70nm

The 400FS70-50 is a Bandpass Filter with a diameter of 50mm, designed for use in the 400nm wavelength range, featuring a high bandwidth of 70nm. This filter is sourced from Andover Corporation, a leading vendor in the optical industry, and is available for purchase through their official website.

The filter is made from UVFS MAL-1965 material, a high-quality, durable substance known for its excellent optical properties. It is designed in a circular shape, with a thickness of 5.9mm, making it suitable for a wide range of optical applications.

The 400FS70-50 filter has a cut-on wavelength of 365nm and a cut-off wavelength of 435nm, with a central wavelength of 400nm. This specific design allows it to transmit light within the specified wavelength range while blocking unwanted light outside this range, enhancing the overall performance of the optical system.

The filter features the same coating on both the front and back, specifically the AND 400FS70 coating. This coating is designed to enhance the filter's performance and durability, ensuring reliable operation and longevity.

The filter is designed in a thin lens shape, which not only reduces its weight but also minimizes optical aberrations, contributing to improved image quality and system performance.
