FEL0900 Dia:1 in Longpass Filter; Cut-On Wavelength: 900nm

The FEL0900 Dia:1 is a Longpass Filter manufactured by Thorlabs, a leading vendor in the optical industry. This filter is designed with a circular base shape and a diameter of 25.4 millimeters, making it compatible with a wide range of optical systems. The filter has a thickness of 3.5 millimeters, providing sufficient structural integrity while maintaining minimal optical impact.

The FEL0900 Dia:1 filter is made of soda lime ru clear material, ensuring high optical quality and durability. It is specifically designed for use with a cut-on wavelength of 900 nanometers, allowing it to effectively filter out unwanted wavelengths below this point. The cut-off wavelength is 0 nanometers, indicating that it does not filter out wavelengths above the cut-on point.

The filter features a Thin Lens shape, which is designed to minimize optical aberrations and distortions. The front and back of the filter are coated with tho fel0900, a specialized coating that enhances the filter's performance and longevity.
