The FGL715 Thorlabs 25 RG715 Glass Filter is a high-quality optical component designed for longpass filtering applications. This filter has a central wavelength of 715 nm, making it ideal for blocking light with wavelengths shorter than 715 nm while allowing light with longer wavelengths to pass through.
The filter is made of RG715 glass, a type of glass that is specifically engineered for use in the near-infrared region of the spectrum. This material provides excellent transmission properties and a flat spectral response, ensuring consistent performance over a wide range of wavelengths.
The FGL715 filter has a thickness of 2.5 mm and a diameter of 25.4 mm, making it a versatile size that can be easily integrated into a variety of optical systems. Its square edge makes it easy to align and mount, while its durable construction ensures that it can withstand the rigors of use in a laboratory or other high-stress environment.
The filter is coated with a high-reflection anti-reflection coating on both sides, which helps to minimize reflection and maximize transmission. This coating also helps to protect the filter from damage and contamination, ensuring that it maintains its performance over time.
In summary, the FGL715 Thorlabs 25 RG715 Glass Filter is a high-quality longpass filter that is ideal for use in applications that require blocking light with wavelengths shorter than 715 nm. Its RG715 glass material provides excellent transmission properties, while its square edge and durable construction make it easy to use and integrate into a variety of optical systems. With its high-reflection anti-reflection coating, this filter ensures consistent performance and long-term durability.
