Benefits
LITHOTEC® i-line glass is offered with the following outstanding properties:
- High refractive index homogeneity values (<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 FK5HT to F14 HT ensures high flexibility in optical designs
