i-Line Glass

Product Information

i-Line glass - for applications requiring high uv-transmittance

i-Line glasses are optical glass types named after the i-wavelength, which offer both high UV-transmittance at 365 nm and high refractive index homogeneity. These glass types, such as N-BK7HTi, FK5HTi, LF5HTi and LLF1HTi are available in customized shapes and as a final component.

Advantages

  • High refractive index homogeneity (PV < 0.5 ppm at 200 mm diameter)
  • Excellent internal quality
  • Negligible stress birefringence due to a well-defined annealing process
  • Variation of absolute refractive index values per lot of less than 5 x 10-5
  • Availability of a wide range of high transmission glass types ensures high flexibility in optical designs
