FGL530 Dia:25 mm OG530 Colored Glass Filter; 530nm Longpass

The FGL530 Dia:25 mm OG530 Colored Glass Filter is a specialized optical component designed for use in systems that require longpass filtering at 530nm. This filter, manufactured by Thorlabs, is a circular shape with a diameter of 25mm and a thickness of 2mm, making it suitable for a wide range of applications.

The filter is made from n-bk7 Schott, a high-quality optical glass known for its excellent transmittance and durability. The filter's primary function is to allow light with wavelengths longer than 530nm to pass through while blocking shorter wavelengths. This is achieved through the application of a specialized coating, denoted as 'tho fgl530' on both the front and back surfaces of the filter.

The FGL530 has a cut-on wavelength of 530nm, meaning it begins to transmit light at this point in the spectrum. However, it does not have a defined cut-off wavelength, as it continues to transmit light at all longer wavelengths. This makes it ideal for applications where longpass filtering is required, such as in fluorescence microscopy or other spectroscopic techniques.

The filter is available for purchase directly from Thorlabs, and as of the time of data collection, it is listed as 'in stock', indicating immediate availability.
