Spectroscopy: Spectroscopes are used in spectrometers to separate incident light into different wavelength ranges to facilitate accurate spectral analysis of samples.

This process, commonly referred to as thin-film deposition, can be achieved through several techniques including physical vapor deposition (PVD), chemical vapor deposition (CVD), or sputtering.

The Angle of Incidence (AOI) for dichroic mirrors is typically 45 degrees. Dichroic mirrors are categorized into short-pass, long-pass, and multi-band dichroic mirrors.

Dichroic mirrors, also known as dichroic filters, play a pivotal role in a wide range of optical applications due to their unique ability to selectively transmit and reflect different wavelengths of light—a fundamental dichroic mirror function.

Reflection wavelength range: This specification refers to the wavelength range of light reflected by a dichroic mirror or beam splitter. It represents the wavelength of light that a mirror or beam splitter effectively reflects rather than transmits.

This allows for the capture of detailed fluorescent images of specimens, enabling researchers to observe cellular structures, proteins, and other biological markers with high specificity and sensitivity.

Making a spectroscope requires highly specialized equipment and technology, and is usually completed by specialized optical manufacturers or research institutions.

Laser system: A beam splitter is an important component in a laser system that is used to combine or separate light beams of different wavelengths. They find applications in laser beam steering, fiber coupling, and wavelength multiplexing.

Optolong utilizes hard dielectric coating technology to enhance the durability of its dichroic mirrors. They employ advanced manufacturing techniques to produce high-quality dichroic mirrors customized for specific applications.

Transmission wavelength range: This specification indicates the wavelength range of light transmitted by a dichroic mirror or beam splitter. It specifies the wavelengths that a mirror or beam splitter allows light to pass through instead of reflecting.

A dichroic mirror, also known as a dual-band mirror, dual-wavelength mirror, or dichroic reflector, and sometimes referred to as a dichroic version of a cold mirror, is typically used behind a light source to reflect visible light while allowing invisible infrared light to pass through.

Optolong’s dichroic mirrors and beam splitters possess several key characteristics that make them suitable for various optical applications, their characteristics are as follows:

The Optolong website offers a variety of dichroic mirror and beam splitter options, whether you need beam splitting or wavelength separation, you can find a solution to suit your needs here, we are always committed to providing expertise to their customers and custom filters to advance the field of optics and contribute to the future of optics.

Beamsplitters are commonly used in various optical systems and instruments for tasks such as directing light along different paths, combining light from multiple sources, or separating light into different wavelengths.

It is important to note that the reflective and transmissive properties of dichroic mirrors depend to some extent on the angle of incidence (AOI) of light. Our dichroic mirrors typically have an AOI of 45 degrees, a design aimed at optimizing the optical performance of the mirrors.

LCD Projectors: In the world of digital imaging and presentation, dichroic mirrors find application in some LCD projectors.

Dichroic mirrors and beamsplitters are optical components with different specifications for specific applications. Their specifications typically include the following:

Selecting the appropriate beamsplitter depends on the specific requirements of the optical system and desired optical performance.

Beamsplitters are usually made of optical glass or similar transparent materials and coated with special optical coatings. These materials and coatings are carefully engineered to achieve the desired optical properties of a beamsplitter, such as splitting incident light into two or more beams, and typically have high transmittance and/or high reflectivity.

Following excitation, these mirrors are designed to pass the emission frequency, which is typically of a longer wavelength than the excitation light.

These filters are utilized to split the white light emitted from the lamp into its primary components—red, green, and blue—before it is passed through the individual LCD units.

These wavelengths may reduce reflectance or transmittance and may appear at the edges or boundaries of the device’s spectral response.

Dichroic filters/dichroic mirrors, excitation filters, and emission filters form the fluorescence filter set used in fluorescence microscopy.

In addition to optical coatings, the fabrication of spectroscopes also involves other process steps, such as substrate selection and preparation, optimization and testing of coatings, quality control, etc.

The design of the coating needs to consider the specific application of the spectroscope, such as wavelength range, optical absorbance, splitting ratio and other factors.

Long-pass Dichroic Mirrors: A long-pass mirror has high reflectance at short wavelengths and high transmittance at longer wavelengths.

To accommodate a broader range of application requirements, Optolong also offers customization services, allowing customers to select different mirror specifications and styles based on their project needs. Click here to contact us!

Each type serves distinct purposes and finds applications in various fields such as biomedical imaging, laser systems, and optical laboratories.

A beamsplitter is an optical device that splits an incident light beam into two or more beams by reflecting a portion of the light while transmitting the remaining portion.

Unlike traditional prism-based systems, dichroic filters offer a more efficient and precise method for color separation, contributing to the overall performance and compactness of the projector.

Dichroic mirrors and beam splitters are important optical components in the field of optics, but they have different uses and exhibit different optical properties.

Short-pass Dichroic Mirrors: A short-pass mirror has a high transmittance at short wavelengths and high reflectance at longer wavelengths.

Biomedical imaging: Spectroscopes are commonly used in fluorescence microscopy and other imaging techniques to separate excitation and emission wavelengths, allowing for selective illumination and accurate capture of fluorescence signals.

Below are detailed applications illustrating the versatility and importance of dichroic mirror function in various technologies:

The manufacturing of dichroic mirrors, a key expertise of dichroic glass manufacturers, primarily involves the deposition of multiple layers of dielectric materials on a transparent substrate, like glass.

Optical coatings are typically constructed from multiple layers of dielectric materials, with precise control of layer thickness and refractive index to achieve the desired optical properties.

Multi-band Dichroic Mirrors: Multi-band dichroic mirrors are a special type of optical component capable of simultaneously reflecting and transmitting light within different wavelength ranges.

In optical experiments and system design, the correct selection of dichroic mirrors or beam splitters is crucial to achieving optical functions.

Optical Coherence Tomography (OCT): OCT imaging systems use beam splitters to split light into a reference arm and a sample arm, enabling high-resolution imaging of biological tissues and materials.

By precisely controlling the thickness and material composition of each layer, a filter that works based on the interference effects of light waves is constructed, thereby enabling the selective reflection and transmission of specific wavelengths of light.

These dichroic mirrors not only boast high transmission efficiency and color fidelity but also demonstrate excellent environmental stability, meeting the needs of various application settings.

This separation process enhances the color purity and brightness of the projected image, leading to a more vivid and engaging viewing experience.

Fluorescence Microscopy: In the realm of scientific research, particularly in the field of biology and medicine, dichroic mirrors are integral components of fluorescence microscopes.

Optical coatings are a vital part of the production of beamsplitters, as they determine the optical properties of the beamsplitter. These coatings are typically applied to the substrate surface using techniques such as physical vapor deposition (PVD) or chemical vapor deposition (CVD).
