FESH0700 Dia:25.0 mm Premium Shortpass Filter; Cut-Off Wavelength: 700nm

The FESH0700 is a high-quality shortpass filter developed by Thorlabs, a leading vendor in the optical industry. This filter, with a catalog number FESH0700, is specifically designed for applications that require the removal of longer wavelengths while allowing shorter wavelengths to pass through.

The filter has a circular shape with a diameter of 25.0 mm and a thickness of 3.5 mm, making it compatible with a wide range of optical systems. It is made from UVFS MAL-1965, a material known for its excellent optical properties.

The FESH0700 has a cut-off wavelength of 700nm, meaning it blocks all wavelengths equal to or greater than this value while transmitting wavelengths below it. This characteristic is crucial in various applications, such as fluorescence microscopy, where it's essential to filter out specific wavelengths to enhance image quality.

The filter's coating is another notable feature. Both the front and back surfaces are coated with "tho fesh0700," a proprietary coating developed by Thorlabs to enhance the filter's performance and durability. The shape of the filter is thin lens, further enhancing its compatibility with various optical systems.
