Dichroic Filter
In the two-way mirror or filter, a optic coating with different refractive rates is created on the glass base. The interface between layers with different refractive rates produces a phase reflection, thereby selectively enhancing some wavelength light and disrupting other wavelengths. These layers are often added by vacuum deposition. By controlling the number of thicknesses and layers, frequency bands can adjust the width of filters and make them wide or narrow as required. Because the desired wavelength is reflected rather than absorbed, the two-way filters do not absorb this unwanted energy in the operation, and therefore do not become more moderately radiant than the traditional filter (in an attempt to absorb all the energy in the band). Similar two-way lenses are now used in cases where white light is deliberately divided into different colour bands (e.g. in colour video projectors or colour television cameras).

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
