420ALP 12.7 mm Dia. Protected Coating; Longpass Filter Protected Coating

The 420ALP is a Longpass Filter, a type of optical filter that passes longer wavelengths of light and blocks shorter wavelengths, from the extensive catalog of Omega Optical. This particular model has a diameter of 12.7 mm and a thickness of 1.5 mm, making it suitable for a wide range of optical applications.

The filter is designed with a cut on wavelength of 420 nm, meaning it starts to transmit light at this wavelength. Notably, it does not have a specified cut off wavelength, indicating that it continues to transmit longer wavelengths without a defined cut off point. This characteristic makes it ideal for applications where the detection of longer wavelengths is crucial.

The 420ALP filter features a protected coating on both the front and back surfaces. This coating enhances the durability and longevity of the filter, providing an extra layer of protection against environmental factors and potential damage during handling or use. The coating also helps to reduce surface reflections, improving the overall efficiency and performance of the filter.
