35-122 12.5 x 12.5 mm Ultra-Thin Longpass Filter OD 2.0 450nm

The 35-122 is a high-quality Longpass Filter, measuring 12.5 x 12.5 mm, sourced from the renowned optical vendor, Edmund Optics. This filter is designed for use in applications where precise wavelength control is required, particularly those involving longpass filtering.

The filter boasts a cut-on wavelength of 450nm, indicating that it begins to transmit wavelengths of 450nm and longer, while blocking shorter wavelengths. The cut-off wavelength is 0nm, meaning it allows all wavelengths longer than the cut-on to pass through. This makes it ideal for applications where the detection of longer wavelengths is crucial.

The filter is made from UVFS Mal-1965, a material specifically chosen for its optical properties, and has a thickness of 0.35mm, making it ultra-thin and suitable for use in compact optical systems. The front and back of the filter are coated with EDM 35-122, a coating that enhances its performance and durability.

The filter's geometry is rectangular, with a width and height of 12.5mm each, providing a large surface area for light to pass through. The shape of the filter is thin lens, indicating that it can also serve as a lens in certain applications.

The filter is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink. With its superior optical performance, robust construction, and versatile design, the 35-122 is an excellent choice for a wide range of optical applications.
