FGL550 Dia:25 mm OG550 Colored Glass Filter; 550nm Longpass

The FGL550 Dia:25 mm OG550 Colored Glass Filter is a high-quality optical component designed for use in a wide range of applications. Manufactured by Thorlabs, a leading vendor in the field of optical components, this filter is a 25mm diameter, 2mm thick circular filter made of n-bk7 Schott material.

The FGL550 filter is a longpass filter, specifically designed to cut on at 550nm and cut off at 0nm. This means it allows all wavelengths of light above 550nm to pass through while blocking all wavelengths below this point. This makes it an ideal choice for applications where specific wavelengths need to be isolated or blocked.

The filter features a Thin Lens shape and is coated with Thorlabs' proprietary Tho FGL550 coating on both the front and back surfaces. This coating enhances the filter's performance and durability, ensuring it maintains its specified characteristics even under demanding conditions.

According to Thorlabs' website, the FGL550 filter is currently in stock, making it readily available for immediate use. Further information about this product, including detailed specifications and purchasing options, can be found on Thorlabs' official website using the provided catalog number.
