FGL515S 2 in x 2 in Square OG515 Colored Glass Filter; 515nm Longpass

The FGL515S is a 2 in x 2 in Square OG515 Colored Glass Filter, specifically designed for longpass applications with a cut-on wavelength of 515nm. This filter is sourced from the renowned optical component manufacturer, Thorlabs.

The filter is made of high-quality N-BK7 Schott glass, a material known for its excellent optical properties and durability. It features a rectangular base shape, with a width and height of 50.8mm each, and a thickness of 2mm, making it suitable for a wide range of optical systems.

The FGL515S filter boasts a unique coating on both the front and back surfaces, denoted as 'tho fgl515'. This coating is specifically designed to enhance the filter's performance in longpass applications, ensuring efficient transmission of wavelengths above 515nm and effective blocking of shorter wavelengths.

The physical data of the filter indicates a cut-on wavelength of 515nm, with no specified cut-off wavelength. This suggests that the filter is designed to pass wavelengths above 515nm, while blocking or attenuating wavelengths below this value.

In terms of availability, the FGL515S filter is currently in stock, according to the vendor's website link provided: https://www.thorlabs.com/thorproduct.cfm?partnumber=FGL515S. This ensures that users can promptly acquire this component for their optical systems.
