Dichroic Filter from Z-Optics is a precision optical component designed to selectively transmit and reflect specific wavelengths of light, enhancing color separation and spectral control in various high-performance optical systems. These filters operate using thin-film interference technology and are typically set at a 45° angle of incidence, reflecting undesired wavelengths while transmitting the targeted light spectrum with high efficiency and durability.

Our dichroic filters are manufactured with high-quality UV-grade fused silica substrates, offering excellent resistance to abrasion and temperature variations. The hard dielectric coatings applied using ion beam sputtering (IBS) technology ensure long life without color degradation. The standard size is 25.2 mm by 35.6 mm by 1 mm with custom dimensions available upon request.

Key features include a sharp transition edge between reflection and transmission bands, a high laser damage threshold, and excellent spectral stability, making them ideal for demanding optical applications.

Applications of Z-Optics Dichroic Filters:

  • LCD Projection Systems: Efficiently separate RGB light components for accurate color rendering.
  • Fluorescence Microscopy: Selectively transmit excitation or emission wavelengths for enhanced imaging contrast.
  • Laser Harmonic Separation: Isolate specific laser wavelengths for precision optical experiments or manufacturing.
  • Multispectral Imaging: Enable high-fidelity wavelength filtering for remote sensing and scientific instrumentation.
  • UV Water Purification Monitoring: Control UV and visible light separation for sensor accuracy.
  • Color Separation in Lighting Fixtures: Improve color quality and energy efficiency in architectural and stage lighting.
  • Optical Instruments: Used in beam splitters and mirrors for aerospace, medical devices, and spectroscopy.
