Product Description

The dichroic longpass filter is an optical filter that reflects specific wavelengths of light while allowing longer wavelengths of light to pass through. It is made of multiple layers of dielectric and metallic materials that selectively reflect and transmit light. In a dichroic longpass filter, shorter wavelength light is reflected from the filter surface while longer wavelength light passes through. This is achieved by using a dichroic coating, which is deposited on a substrate such as glass or quartz. The coating is designed so that at a specific wavelength (the cutoff wavelength), the filter reflects 50% of the light and transmits the other 50%. Beyond this wavelength, the filter increasingly transmits more light while reflecting less. Dichroic longpass filters are commonly used in scientific and industrial applications where separation and control of different wavelength regions of light is important. For example, they can be used in fluorescence microscopy to separate excitation wavelengths from emission wavelengths. They are also used in lighting and projection systems to control color temperature and brightness. Dichroic longpass filters can be designed with different cut-off wavelengths according to specific application requirements. They can also be integrated with other optical components to form more complex optical systems, such as multi-spectral imaging systems.
