PRODUCT
Detail
A cube beamsplitter is an optical component. It is constructed by cementing two right-angle prisms together to create a cubic structure.One hypotenuse surface with partial reflection coating. Its core function is to split the incident light in a specific ratio (for example, a 50:50 cube-shaped beam splitter will transmit 50% of the incident light's energy and reflect 50% of it). It is widely used in fields such as optical interferometric measurement, laser processing and optical systems, spectral analysis and measurement.
