FSR-OG570 25.4 mm Dia. Colored Glass Absorptive Longpass Filter 570nm

The FSR-OG570 is a Longpass Filter, specifically designed for use in optical systems that require a 570nm cut-on wavelength. This filter is sourced from the reputable vendor, MKS/Newport, and boasts a catalog number of FSR-OG570. Interested users can find more information and check its availability on the vendor's official website (https://www.newport.com/p/FSR-OG570).

This filter is made of high-quality glass, with a circular shape and a diameter of 25.4mm. It has a thickness of 3mm, providing excellent durability and stability in various optical applications. The filter's coating, both on the front and back, is 'new og570', which contributes to its longpass filtering capabilities.

The FSR-OG570 has a physical data specification of a 570nm cut-on wavelength and a 0nm cut-off wavelength. This means it starts absorbing wavelengths from 570nm and above, making it ideal for applications where such wavelength filtration is required.

The filter's geometry is shaped as a thin lens, which can be beneficial in certain optical system designs. It is important to note that the filter's material ID is UVFS MAL-1965, which might be a crucial factor in specific applications.
