Optolong's dichroic mirrors are suitable for the following wavelength ranges: 405nm, 460nm, 500nm, 505nm, 562nm, 565nm, 575nm, 585nm, 605nm and 662nm.

Extreme care should be taken when cleaning dichroic mirrors. Here are detailed instructions on how to clean and maintain a dichroic mirror:

Gentle Cleaning: Use a soft, lint-free cloth and a mild cleaning solution designed for optical surfaces, making sure not to use harsh chemicals or materials that could scratch the mirror.

Avoid harsh chemicals: Make sure not to use abrasive cleaners or other materials that could cause damage to the mirror coating.

Light Touch: Apply minimal pressure when cleaning to avoid damaging the coating. Gentle wiping reduces the risk of scratches and damage.

Dust regularly: Use a soft cloth to dust regularly to prevent dust, debris or dirt from accumulating on the mirror surface and maintain a clean state.

Avoid moisture: Make sure to keep your mirror dry, as too much moisture can damage the coating. Avoid exposing mirrors to high humidity.

Storage: Store the mirror in a clean, dry place to protect it from damage by environmental factors such as dust, moisture, etc.

Yes, our dichroic mirrors feature an anti-scratch coating for enhanced durability and scratch resistance.

Yes, Optolong's dichroic mirrors support customization. You only need to contact Optolong to ask if they can customize a dichroic mirror that meets your needs. They will consider your customized needs and provide corresponding quotes and services.

Optolong's standard fluorescence filters and astronomy filters can be shipped the same day upon receipt of payment.

Other stock filters in different sizes (such as custom mirror filters) can be shipped within 15 days after payment confirmation.

Dichroic mirrors and beamsplitters are similar in that they both control light, but their functions are different:

Dichroic Mirrors: These mirrors are designed to selectively pass certain wavelengths of light while reflecting other wavelengths. They are often used in applications where specific wavelengths need to be separated or filtered.

Beam Splitter: A beam splitter is an optical device that splits a beam of light into two or more separate beams. They typically split light based on intensity rather than wavelength and are used in a variety of optical systems to split light paths.

In summary, while both dichroic mirrors and Dichroic Beam Splitter manage light, dichroic mirrors focus on wavelength selection, while beam splitters focus on splitting light into separate beams.

No, Optolong's dichroic mirrors will have different prices according to different specifications.
