FGL665M Dia. 25 mm SM1-Mounted Colored Glass Filter; 665nm Longpass

The FGL665M is a color glass filter developed by Thorlabs, featuring a 25 mm diameter and a 2 mm thickness. This filter is designed for use in SM1-mounted systems, providing a convenient and secure method for incorporating it into optical setups. The FGL665M is a longpass filter, with a cut-on wavelength of 665 nm, making it ideal for applications that require the blocking of shorter wavelengths while transmitting longer ones.

The filter's material is n-bk7 Schott, a borosilicate glass known for its excellent optical properties and durability. This material ensures high transmission and low absorption across the visible spectrum, making the FGL665M a reliable choice for various optical applications. The filter's coating, identified as 'tho fgl665' on both the front and back surfaces, further enhances its performance by providing additional protection against environmental factors and ensuring consistent optical properties over time.

The FGL665M's thin lens shape allows for easy integration into optical systems, while its 25 mm diameter provides a generous aperture for efficient light transmission. The filter's geometry, combined with its high-quality materials and coatings, make it a versatile and robust component for a wide range of optical applications.

According to the vendor's information, the FGL665M is currently in stock, ensuring quick and reliable delivery for those interested in incorporating this filter into their optical systems.
