FES0700 Dia:1 in Shortpass Filter; Cut-Off Wavelength: 700nm

The FES0700 Dia:1 is a Shortpass Filter, part of the extensive catalog of optical elements offered by Thorlabs. This filter, designed for use in a variety of optical applications, features a circular shape and a diameter of 25.4mm, ensuring compatibility with a wide range of systems.

The filter is made from soda lime ru clear, a material known for its optical clarity and durability. It has a thickness of 3.5mm, providing robustness and stability in operation. The filter's coating, applied to both the front and back surfaces, is a crucial component of its design. The front coating, tho fes0700, is specifically designed to enhance the filter's performance in its intended application.

The FES0700 Dia:1 has a cut-off wavelength of 700nm, meaning it allows light of shorter wavelengths to pass through while blocking or attenuating longer wavelengths. This characteristic makes it suitable for applications where the removal of specific wavelengths is required.

The filter's physical data further highlights its capabilities. With a cut-on of 0, it begins to transmit light immediately, providing a broad range of usable wavelengths. The filter's geometry, including its diameter and thickness, has been optimized for use in a variety of optical systems.
