32-754 25.4 mm Dia. SCHOTT OG550 Orange Longpass Color Glass Filter 550nm

The 32-754 25.4 mm Dia. SCHOTT OG550 Orange Longpass Color Glass Filter is a specialized optical component designed for applications that require longpass filtering at a specific wavelength. This filter, sourced from the renowned optical vendor Edmund Optics, is a circular element with a diameter of 25.4 mm and a thickness of 3 mm, making it suitable for a wide range of optical systems.

The filter is made from SCHOTT OG550, a high-quality optical glass known for its excellent transmission properties in the orange spectrum. The filter's primary function is to pass light with wavelengths above 550 nm while blocking or attenuating light with shorter wavelengths. This makes it ideal for applications such as fluorescence microscopy, where it can be used to isolate the emission spectrum of a fluorophore from excitation light.

The filter's coating, EDM 54-655, is applied to both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission in the passband. The coating also provides a measure of environmental protection, helping to prevent damage from dust, moisture, and other contaminants.

The 32-754 filter is shaped as a thin lens, which can be beneficial in certain optical configurations. This shape, combined with the filter's high-quality construction and reliable performance, makes it a valuable addition to any optical system that requires longpass filtering at the 550 nm wavelength.
