FSR-RG780 25.4 mm Dia. Colored Glass Absorptive Longpass Filter 780nm

The FSR-RG780 is a longpass filter with a 25.4 mm diameter, designed for use in optical systems that require the removal or isolation of specific wavelengths. This filter, offered by MKS/Newport, has a catalog number of FSR-RG780 and is available for purchase online. The filter's current status indicates that it is in stock, ensuring quick delivery for your optical project needs.

The FSR-RG780 filter is made of colored glass, a material known for its excellent optical properties and durability. It is designed to absorb light at wavelengths shorter than 780nm, while allowing light at longer wavelengths to pass through. This makes it ideal for applications where infrared light needs to be isolated or blocked.

The filter has a circular shape, a standard in optical systems due to its symmetry and ease of alignment. It has a thickness of 3mm, providing sufficient structural integrity while minimizing the impact on the optical path.

The filter's coating is another crucial aspect of its design. Both the front and back surfaces are coated with a new RG780 coating, which enhances the filter's performance and longevity. This coating ensures optimal light transmission and absorption, contributing to the overall efficiency of your optical system.

The FSR-RG780 filter is designed in the shape of a thin lens, allowing it to be easily integrated into various optical systems. Its dimensions and shape make it a versatile component, suitable for a wide range of applications.
