FGL715S 2 in x 2 in Square RG715 Colored Glass Filter; 715nm Longpass

The FGL715S is a 2 in x 2 in Square RG715 Colored Glass Filter, specifically designed for longpass applications at 715nm. This filter is sourced from the renowned optical component manufacturer, Thorlabs.

The filter is made of n-bk7 Schott, a high-quality borosilicate glass known for its excellent optical properties. It features a rectangular base shape, with a width and height of 50.8mm each, and a thickness of 2mm, making it suitable for various optical systems.

The FGL715S boasts a cut-on wavelength of 715nm, meaning it starts transmitting light at this wavelength, while blocking or attenuating wavelengths below this point. The cut-off wavelength is 0nm, indicating that it allows all wavelengths above 715nm to pass through.

The filter's coating is another notable feature. Both the front and back surfaces are coated with tho fgl715, a proprietary coating developed by Thorlabs to enhance the filter's performance and durability. The coating ensures high transmission and low reflection, making the filter an ideal choice for applications requiring efficient light transmission.

The FGL715S is available in a thin lens shape, which is beneficial for applications where space is a constraint. According to Thorlabs' website, the filter is currently in stock, ensuring quick delivery for your optical system needs.
