66-108 50 mm Dia. SCHOTT RG1000 Black Longpass Color Glass Filter 1000nm

The 66-108 is a 50 mm diameter circular filter from the reputable vendor, Edmund Optics. This filter is specifically designed for longpass applications, with a cut-on wavelength of 1000nm. The RG1000 designation signifies its ability to transmit wavelengths of 1000nm and above, making it ideal for applications that require the blocking of shorter wavelengths.

The filter is made from Schott glass, a high-quality optical glass known for its excellent transmittance, homogeneity, and durability. The glass is cut to a thickness of 3mm, providing a good balance between mechanical strength and optical performance.

The filter features a thin lens shape, which helps to minimize optical aberrations and distortions. This is particularly beneficial in imaging applications where high resolution and accuracy are required.

The front and back surfaces of the filter are coated with EDM 54-665, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance by reducing surface reflections and improving transmission efficiency. It also provides protection against environmental factors such as dust, moisture, and scratches, ensuring the longevity and reliability of the filter.

In terms of dimensions, the filter has a diameter of 50mm, making it suitable for use with a wide range of optical systems. The filter is currently in stock and available for immediate dispatch, as indicated by its valid weblink status.
