FELH0950 Dia:25.0 mm Premium Longpass Filter; Cut-On Wavelength: 950nm

The FELH0950 is a high-quality longpass filter, manufactured by Thorlabs, a renowned vendor in the optical industry. This filter is designed with a circular shape, featuring a diameter of 25.0 mm and a thickness of 3.5 mm, making it compatible with a wide range of optical systems.

The filter's primary function is to allow the transmission of light with wavelengths greater than or equal to 950nm, while blocking light with shorter wavelengths. This is achieved through the application of a specialized coating, denoted as 'tho felh0950' on both the front and back surfaces. The 'tho felh0950' coating ensures a sharp cut-on at the specified wavelength, enhancing the filter's performance and reliability.

The FELH0950 is categorized as a premium filter, implying that it has been subjected to rigorous quality control measures and testing to ensure its optical performance and durability. The filter's geometry is designed in the shape of a thin lens, which not only contributes to its compactness but also minimizes optical aberrations, thereby improving the overall performance of the optical system in which it is integrated.

The filter's current status is 'in stock', as indicated by its weblink, which is valid and leads to the product's page on Thorlabs' official website. This information is particularly useful for users who are interested in immediate procurement of the item.
