FSR-RG695 25.4 mm Dia. Colored Glass Absorptive Longpass Filter 695nm

The FSR-RG695 is a longpass filter with a 25.4 mm diameter, designed for use in optical systems that require the removal or reduction of specific wavelengths of light. This filter, offered by MKS/Newport, is made of colored glass and features an absorptive coating, which effectively blocks light below 695nm while allowing light at and above this wavelength to pass through.

The filter has a thickness of 3mm, providing durability and stability in its placement within an optical system. Its thin lens shape allows for easy integration into various setups. The front and back surfaces of the filter are coated with the same New RG695 coating, ensuring consistent performance and protection for the filter material.

The FSR-RG695 is part of the UVFS Mal-1965 material family, which is known for its high-quality optical properties. The cut-on wavelength for this filter is 695nm, meaning it begins to transmit light at this point in the spectrum. The cut-off wavelength is 0nm, indicating that it blocks all wavelengths below its specified cut-on point.

This filter is currently in stock and available for purchase through the Newport website. Its catalog number, FSR-RG695, can be used for easy reference and identification. With its robust design, specific wavelength blocking capabilities, and high-quality construction, the FSR-RG695 is an excellent choice for a variety of optical applications.
