FELH0750 Dia:25.0 mm Premium Longpass Filter; Cut-On Wavelength: 750nm

The FELH0750 is a high-quality longpass filter, manufactured by Thorlabs, with a cut-on wavelength of 750nm. This filter is designed for use in a wide range of optical applications, thanks to its premium optical properties and robust construction.

The filter is circular in shape, with a diameter of 25.0 mm, making it suitable for use in various optical systems. It has a thickness of 3.5 mm, which contributes to its durability and stability. The FELH0750 features a thin lens shape, which is beneficial in applications where a flat filter surface is required.

The FELH0750 filter is made from UVFS material, specifically identified as 'mal- 1965'. This material is known for its excellent optical properties, including high transmittance and low absorption. The filter's coating is another notable feature. Both the front and back surfaces of the filter are coated with 'tho felh0750', which enhances its performance and durability.

The filter's physical data is also impressive. With a cut-on wavelength of 750nm, it effectively blocks wavelengths below this point while allowing those above to pass through. The cut-off wavelength is 0nm, indicating that it allows all wavelengths above 750nm to pass through.
