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
