Dichroic Mirrors

Name: Dichroic Mirrors
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

Dichroic mirrors are composed of optical mirrors and thin-film dielectric coatings, which can split light of a certain wavelength into two parts, one part passes through, and the other part is reflected or absorbed. Filters that allow longer wavelengths of light to pass are called long-pass filters, and filters that allow shorter wavelengths of light to pass are called short-pass filters. The processing technology of Tianyanggu dichroic mirrors is mature and it is easy to achieve high-precision dimensions. The precision of prisms with a size of less than 3 inches can be controlled within 3 seconds. The dichroic mirror is milled, finely ground, ground, polished, and coated to achieve high-precision mirror flatness and optical properties.

Applications of Dichroic Mirrors in Imaging Systems

Dichroic mirrors play a crucial role in modern imaging systems by enabling the precise separation and manipulation of different wavelengths of light. These dichroic mirrors are essential in fluorescence microscopy, where they selectively reflect excitation light while transmitting emitted fluorescence, thereby enhancing image clarity and contrast. In multi-spectral imaging systems, dichroic mirrors facilitate the simultaneous capture of images at different wavelengths, allowing for detailed analysis of complex samples. Additionally, they are used in optical coherence tomography (OCT) to separate reference and sample beams, improving the resolution and depth of imaging. The high efficiency and wavelength specificity of dichroic mirrors make them indispensable in applications ranging from medical diagnostics to advanced scientific research, where accurate and high-quality imaging is paramount.
