54-657 12.5 mm Dia. SCHOTT OG590 Red Longpass Color Glass Filter 590nm

The 54-657 12.5 mm Dia. SCHOTT OG590 Red Longpass Color Glass Filter is a specialized optical component designed for applications that require longpass filtering at a specific wavelength. This filter, sourced from Edmund Optics, is a circular element with a 12.5 mm diameter and a thickness of 3 mm, making it suitable for a wide range of optical systems.

The filter is made from SCHOTT optical glass, a high-quality material known for its excellent optical properties. The OG590 designation indicates that this filter has a cut-on wavelength of 590 nm, meaning it begins to transmit light at this wavelength and beyond. The cut-off wavelength is 0 nm, indicating that it blocks all wavelengths of light below 590 nm. This makes it ideal for applications where red light and longer wavelengths need to be isolated or emphasized.

The filter features a thin lens shape, which can be beneficial in certain optical configurations. It is coated on both the front and back surfaces with the EDM 54-657 coating, which likely enhances its performance in specific applications. However, the exact nature of this coating is not specified in the provided data.
