FGL515 Dia:25 mm OG515 Colored Glass Filter; 515nm Longpass

The FGL515 Dia:25 mm OG515 Colored Glass Filter is a specialized optical component designed for longpass wavelength applications. Sourced from the renowned vendor Thorlabs, this filter is a part of their extensive catalog, boasting a catalog number FGL515.

This filter is a Color Glass type, characterized by its base shape of a circle and a diameter of 25 mm. It is crafted from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties. The filter's geometry includes a thickness of 2 mm, providing robustness and stability.

The FGL515 filter is designed for 515 nm longpass applications, with a physical data cut-on wavelength of 515 nm. The cut-off wavelength is 0 nm, indicating that it allows all wavelengths shorter than the cut-on to pass through. This makes it ideal for applications where longer wavelengths need to be blocked or filtered out.

The filter's coating is a crucial aspect of its functionality. Both the front and back surfaces are coated with the THo FGL515 coating, enhancing its performance and durability. The filter's shape is that of a Thin Lens, further expanding its potential applications in optical systems.

According to the vendor's information, the FGL515 filter is currently in stock and its weblink is valid. This ensures that users can promptly acquire this component for their optical systems.
