FGL610 Dia:25 mm RG610 Colored Glass Filter; 610nm Longpass

The FGL610 Dia:25 mm RG610 Colored Glass Filter is a high-quality optical component designed for longpass applications, sourced from the renowned vendor Thorlabs. This filter is specifically designed to transmit light with wavelengths above 610 nm while blocking shorter wavelengths.

The filter boasts a circular shape with a diameter of 25 mm and a thickness of 2 mm, making it compatible with a wide range of optical systems. It is crafted from n-bk7 Schott, a high-grade optical glass known for its excellent transmittance and durability.

The FGL610 features a sophisticated coating on both the front and back surfaces, denoted as 'tho fgl610'. This coating enhances the filter's performance by ensuring a sharp cut-on wavelength of 610 nm, with no cut-off wavelength specified, indicating a high transmission efficiency in the specified wavelength range.

The filter's physical data further highlights its capabilities. With a cut-on wavelength of 610 nm, it effectively blocks unwanted shorter wavelengths, allowing only the desired longer wavelengths to pass through.

The FGL610's shape is classified as a Thin Lens, suggesting its potential use in lens systems. This versatile filter is currently in stock and available for immediate use, as indicated by its weblink status.
