  • N-BK7 Windows and H-K9L Windows

    Made from BK7 material, which has transparent range from 330-2100nm. The refractive index is 1.5168 at 587.6nm. The BK7 window has good performance over visible and near IR spectrum for most application.

  • High Precision Achromatic Waveplate

    Achromatic Waveplate Achromatic Waveplates(Retarders), AWP is composed of one piece of Crystal Quartz and one piece of Magnesium Fluoride, MgF2.

  • IR Windows Barium Fluoride BaF2 Window

    Barium fluoride (BaF2) shows good optical transmission over UV-IR windows in 0.15μm~12.5μm.

  • IR Windows Magnesium Fluoride MgF2 Windows

    MgF2 windows are used in the UV, visible and IR ranges, with approximately 94% transmission from 200 - 1000 nm, and approximately 95% transmission from 1-6µm

  • IR Windows Calcium fluoride CaF2 Windows

    CaF2 has transparent range from 170-7800nm. The refractive index is 1.399 at 5000nm. 1. Low absorption coefficient 2. High damage threshold, 3. Low Dispersion (with an Abbe Number of 95) 4. Low fluorescence 5. Excellent water, chemical, and heat resistance
