FGL630 Dia:25 mm RG630 Colored Glass Filter; 630nm Longpass
The FGL630 Dia:25 mm RG630 Colored Glass Filter is a high-quality optical component designed for longpass filtering at 630nm. This filter is sourced from Thorlabs, a renowned vendor in the optical industry, and is available for purchase through their official website.
The filter is a circular piece of n-bk7 Schott glass, a material known for its excellent optical properties. It has a diameter of 25mm and a thickness of 2mm, making it suitable for a wide range of optical applications. The FGL630 features a thin lens shape, which is beneficial for maintaining the integrity of the optical path.
The FGL630's primary function is to cut on at 630nm and cut off at 0nm. This means it allows light with wavelengths greater than or equal to 630nm to pass through while blocking light with wavelengths less than 630nm. This makes it an ideal choice for applications that require the selective filtering of specific wavelengths.
The filter's coating is another notable feature. Both the front and back surfaces of the filter are coated with the THo FGL630 coating, which enhances its performance and durability. This coating helps to ensure that the filter maintains its specified optical properties over time, even with regular use.
