Product Case Studies

Dichroic filter

• Dual wavelength selectivity: A dichroic filter selectively transmits light of two different wavelength ranges, enabling optical separation of multiple wavelengths.
• High transmittance: For selectively transmitted light in two wavelength ranges, dichroic filters typically have high transmittance, ensuring the brightness and clarity of the optical system.
• Wavelength Separation: A dichroic filter can effectively separate two different wavelength ranges of light for optical spectroscopy and imaging.
• Reflection and blocking: For light in other wavelength ranges, dichroic filters can reflect or block, achieving the suppression of stray light in optical systems.

describe

A dichroic filter is an optical component that selectively transmits light of two different wavelength ranges while reflecting or blocking light of other wavelength ranges. A dichroic filter is usually composed of multiple layers of optical films, which use the principles of interference and reflection to achieve selective transmission and reflection of light within a specific wavelength range.

application area

• Fluorescence microscope: In a multi-channel fluorescence microscope system, a dichroic filter can be used to separate fluorescence signals of different wavelengths emitted by different fluorescent dyes.
• Imaging system: In multispectral imaging systems, dichroic filters can be used to separate light of different wavelength ranges, achieving multispectral imaging.
• Optical sensor: In optical sensor systems, dichroic filters can be used to selectively transmit light within a specific wavelength range, achieving accurate optical measurements.
• Laser: In a laser system, a dichroic filter can be used to selectively pass through two different wavelength ranges of laser light emitted by the laser.

Manufacturing and Design

The manufacturing of dichroic filters requires precise optical film deposition techniques and complex thin film design to achieve selective transmission and reflection of light in two different wavelength ranges. When designing, two wavelength ranges, transmittance, wavelength resolution, and other parameters need to be considered to meet the optical requirements of specific applications. High precision thin film deposition equipment and high-quality optical materials are required during the manufacturing process to ensure stable and reliable performance of the filter.

Overall, dichroic filters, as an optical component with dual wavelength selectivity, play an important role in applications that require multi wavelength optical separation and imaging. Its dual wavelength selectivity and high transmittance make it an indispensable component in optical system design.
