FESH0550 Dia:25.0 mm Premium Shortpass Filter; Cut-Off Wavelength: 550nm

The FESH0550 is a high-quality shortpass filter, manufactured by Thorlabs, with a diameter of 25.0 mm and a thickness of 3.5 mm. This filter is designed to transmit light with wavelengths shorter than the specified cut-off wavelength of 550nm, while blocking or attenuating longer wavelengths.

The FESH0550 features a circular base shape and is made from UVFS material, identified as MAL-1965. The filter's coating, applied to both the front and back surfaces, is designated as 'tho fesh0550'. This coating enhances the filter's performance, ensuring precise wavelength selectivity and high transmission efficiency.

The physical dimensions of the FESH0550 are optimized for use in a variety of optical systems. Its thin lens shape allows for easy integration into existing setups. The filter's geometry, combined with its high-quality coating, makes it an ideal choice for applications requiring precise wavelength control and high-transmission performance.
