FGL665 Dia:25 mm RG665 Colored Glass Filter; 665nm Longpass

The FGL665 Dia:25 mm RG665 Colored Glass Filter is a high-quality optical component manufactured by Thorlabs. This filter is designed with a longpass wavelength of 665nm, making it ideal for applications that require the transmission of infrared light while blocking shorter wavelengths.

The filter is circular in shape with a diameter of 25mm and a thickness of 2mm, providing a compact and robust design suitable for various optical systems. It is made from n-bk7 Schott, a widely used optical glass known for its excellent optical properties and durability.

The FGL665 filter features a thin lens shape, which is designed to minimize optical aberrations and ensure high-quality image transmission. The filter's coating, denoted as 'tho fgl665' on both the front and back surfaces, enhances its performance by reducing reflection and increasing transmission efficiency.
