FR-OG550 12.7 mm Dia. Colored Glass Absorptive Longpass Filter 550nm

The FR-OG550 is a Longpass Filter, specifically designed for use in optical systems that require the removal or reduction of specific wavelengths of light. This filter, sourced from MKS/Newport, has a catalog number of FR-OG550 and is available for purchase directly from their website. The filter's current status is "Valid - in stock", indicating it is readily available for immediate use.

The filter is circular in shape, with a diameter of 12.7 mm and a thickness of 3 mm, making it suitable for a wide range of optical applications. The base shape of the filter is a Thin Lens, which is designed to minimize optical aberrations and distortions.

The FR-OG550 filter features a coating on both the front and back surfaces. This coating, identified as "new og550", is specifically designed to absorb light at wavelengths shorter than 550 nm, while allowing light at longer wavelengths to pass through. This makes it ideal for use in applications where the removal of shorter wavelengths is necessary.

The filter's physical data includes a cut-on wavelength of 550 nm and a cut-off wavelength of 0 nm. This means that the filter begins to absorb light at 550 nm and continues to absorb all shorter wavelengths. The cut-off wavelength of 0 nm indicates that the filter will continue to absorb all wavelengths of light, making it a highly effective longpass filter.
