FSR-RG610 25.4 mm Dia. Colored Glass Absorptive Longpass Filter 610nm

The FSR-RG610 is a Longpass Filter, specifically designed for use in optical systems that require a sharp cut-off at a particular wavelength. This filter, sourced from the reputable vendor MKS/Newport, is characterized by its circular shape with a diameter of 25.4 mm and a thickness of 3 mm, making it suitable for a wide range of applications.

The filter's primary function is to allow the transmission of light at wavelengths above 610 nm, while effectively blocking light at wavelengths below this point. This is achieved through the use of a specialized coating, denoted as 'new rg610' on both the front and back surfaces. The cut-on wavelength is 588 nm, further emphasizing the filter's ability to block unwanted shorter wavelengths.

The FSR-RG610 is categorized under the Material ID UVFS MAL-1965, indicating its specific composition and properties. It features a 'Thin Lens' shape, which can be beneficial in certain optical configurations. The filter's physical data, including its cut-on and cut-off wavelengths, are provided to ensure users have a comprehensive understanding of its capabilities.

According to the vendor's website, the FSR-RG610 is currently in stock, making it readily available for immediate use. The catalog number for this item is FSR-RG610, and users can find more information, including pricing and availability, on the Newport website.
